New Deadly Mystery Virus. New Pandemic?

If you'll recall, I reported on mass animal deaths back on April 12, 2013 (REFER TO POST HERE).  One of the mass animal deaths listed was located in China, where there were bloated pigs floating in some waterways and the deaths were only explained as "respiratory failure due to inhaling toxic gas" (REFER TO CHINA NEWS POST HERE).  Well, it turns out that the numbers of dead pigs were much higher than I first posted and there were dead dogs as well.  Additionally, the local authorities could not determine for certain that the animals actually died because of inhalation of toxic gas and now there is more proof that they may have been sick with the newest mystery virus called H7N9.

The World Health Organization does not have a handle on this illness, except to say that it is not SARS, but is symptomatically similar to SARS and that it can be transmitted person-to-person.  So far, this illness has spread in clusters in many countries.  

Also, the WHO says that they (and we) are not ready for a mass flu outbreak.  They said that one day and then the next said that they have the outbreak under control.  Have you seen Survivors?  This is so similar to that case scenario that it is somewhat nerve-racking.  Do we trust that they have it under control, or do we trust that they have our panic under control?  

Here is more information and commentary regarding this illness (H7N9).   The information is suspect because it is not consistent, which makes the remarks that the World Health Organization said even harder to believe.  As far as I am concerned, there is no panic.  However, I don't trust that this new strain is under control.  

Is this the next pandemic? Tale of mystery virus unfolds like a movie plot (Commentary)

By LAURIE GARRETT

WASHINGTON — Here’s how it would happen. Children playing along an urban river bank would spot hundreds of grotesque, bloated pig carcasses bobbing downstream. Hundreds of miles away, angry citizens would protest the rising stench from piles of dead ducks and swans, their rotting bodies collecting by the thousands along river banks. And three unrelated individuals would stagger into three different hospitals, gasping for air. Two would quickly die of severe pneumonia and the third would lay in critical condition in an intensive care unit for many days. Government officials would announce that a previously unknown virus had sickened three people, at least, and killed two of them. And while the world was left to wonder how the pigs, ducks, swans, and people might be connected, the World Health Organization would release deliberately terse statements, offering little insight.

It reads like a movie plot — I should know, as I was a consultant for Steven Soderbergh’s “Contagion.” But the facts delineated are all true, and have transpired over the last six weeks in China.

The events could, indeed, be unrelated, and the new virus, a form of influenza denoted as H7N9, may have already run its course, infecting just three people and killing two.

Or this could be how pandemics begin.

On March 10, residents of China’s powerhouse metropolis, Shanghai, noticed some dead pigs floating among garbage flotsam in the city’s Huangpu River.

The vile carcasses appeared in Shanghai’s most important tributary of the mighty Yangtze, a 71-mile river that is edged by the Bund, the city’s main tourist area, and serves as the primary source of drinking water and ferry travel for the 23 million residents of the metropolis and its millions of visitors.

The vision of a few dead pigs on the surface of the Huangpu was every bit as jarring for local Chinese as porcine carcasses would be for French strolling the Seine, Londoners along the Thames, or New Yorkers looking from the Brooklyn Bridge down on the East River.

And the nightmarish sight soon worsened, with more than 900 animal bodies found by sunset on that Sunday evening.

The first few pig carcass numbers soon swelled into the thousands, turning Shanghai spring into a horror show that by March 20 would total more than 15,000 dead animals.

The river zigzags its way from Zhejiang province, just to the south of Shanghai, a farming region inhabited by some 54 million people, and a major pork-raising district of China. Due to scandals over recent years in the pork industry, including substitution of rendered pig intestines for a toxic chemical, sold as heparin blood thinner that proved lethal to American cardiac patients, Chinese authorities had put identity tags on pigs’ ears.

The pig carcasses were swiftly traced back to key farms in Zhejiang, and terrified farmers admitted that they had dumped the dead animals into the Huangpu.

Few Chinese asked, “What killed the pigs?,” because river pollution is so heinous across China that today people simply assume manufacturing chemicals or pesticides fill the nation’s waterways, and are responsible for all such mysterious animals demises.

The Yangtze, which feeds Shanghai’s Huangpu, has copper pollution levels that are 100 times higher than U.S. safety standards, and leather tanning facilities along the river have notoriously been responsible for toxic waste, including chromium.

And across China — especially in Beijing — air pollution was so bad in January and February that pollution particulate levels routinely peaked at higher than 10 times the U.S. safety standards set by the Environmental Protection Agency.

When I was in Beijing in late January, the air pollution was so thick that it visually looked like fog, obscuring all sunlight and even skyscrapers located less than three city blocks away.

So, hideous as the pig carcasses might be, Shanghai residents tended to shrug them off as yet another example of the trade-offs China is making, pitting prosperity against pollution.

Mystery Coronavirus Renamed Middle East Respiratory Syndrome Coronavirus As Two Saudi Healthcare Workers Fall Ill

As the new coronavirus spreads and infects more people, especially those who have traveled to Saudi Arabia, a formal name is finally given to the faceless killer.

The WHO's assistant director general for health security and the environment, Keiji Fukuda, told a Riyadh news conference on Sunday the new virus posed an "important and major challenge" for countries affected and the world generally.

He said experts were still grappling to understand all aspects of the virus and how humans become infected, stressing, however, that "this new virus is not the SARS virus."

"This is a new infection and there are also many gaps in our knowledge that will inevitably take time to fill in," a WHO statement cited Mr Fukuda as saying.

"Of most concern, however, is the fact that the different clusters seen in multiple countries increasingly support the hypothesis that when there is close contact this novel coronavirus can transmit from person-to-person," he said.

"This pattern of person-to-person transmission has remained limited to some small clusters, and so far, there is no evidence that this virus has the capacity to sustain generalised transmission in communities."

World not ready for mass flu outbreak, says WHO

The world is unprepared for a massive virus outbreak, the deputy chief of the World Health Organisation warned on Tuesday, amid fears that H7N9 bird flu striking China could morph into a form that spreads easily among people.
Keiji Fukuda told delegates at a WHO meeting that despite efforts since an outbreak of another form of avian influenza, H1N1, in 2009-10, far more contingency planning was essential.
Rapid-reaction systems were crucial, given that health authorities’ efforts are already hampered by lack of knowledge about such diseases, he insisted.“Even though work has been done since that time, the world is not ready for a large, severe outbreak,” Fukuda said.
“When people get hit with an emerging disease, you can’t just go to a book and know what to do,” he said.
According to the latest official data, H7N9 avian influenza has infected 130 people in China, and killed 35, since it was found in humans for the first time in March.
It is one of a vast array of flu viruses carried by birds, the overwhelming majority of which pose little or no risk to humans.
Experts are struggling to understand how it spread to people, amid fears that it could adapt into a form that can be transmitted easily from human to human.

H7N9 bird flu appears contained, UN health experts say

International experts praise China's efforts, but note outbreak has cost economy US$6.5b
The H7N9 virus appears to have been brought under control in China largely due to restrictions at bird markets, but caused some US$6.5 billion in losses to the economy, UN experts said.
Health authorities worldwide must be on the lookout to detect the virus, which could still develop the ability to spread easily among humans and cause a deadly influenza pandemic, the experts said.
The new bird flu virus is known to have infected 130 people in mainland China since emerging in March, including 36 who died, but no cases have been detected since early May, Health Minister Li Bin told the World Health Organisation.
One case was found in Taiwan in April, making a total of 131.
"The immediate outbreak has been controlled, but it is also unlikely that virus has simply disappeared. We believe we need go another autumn/winter/spring season to know," said Dr Keiji Fukuda, WHO assistant director general for health security.
"We also have high concern over the potential, I stress the potential, to gain the ability to sustain transmissibility."
There was no evidence of sustained spread among people and "most cases probably resulted from infected poultry or perhaps contamination related to live poultry markets", Fukuda said.

Drug-resistant cases of a deadly new strain of bird flu have been identified.
In a study published in The Lancet on May 28, researchers detailed three patients with the new avian flu strain that's hit China, known as H7N9, whose sickness could not be treated by Tamiflu (oseltamivir) and similar drugs.
"The apparent ease with which antiviral resistance emerges in A/H7N9 viruses is concerning; it needs to be closely monitored and considered in future pandemic response plans," the authors wrote.

Two new viruses threaten global outbreaks

H7N9 is the name for a subtype of influenza viruses that is often found in birds, according to the Centers for Disease Control and Prevention. However, a new H7N9 strain discovered in China looks different from previous strains. Prior to this China strain, H7N9 had never been detected in humans. TheWorld Health Organization said 131 people have been infected with the new bird flu as of May 24, including 36 deaths.
There is no solid evidence yet of human-to-human transmission, though there is concern the virus can mutate to a strain spread more easily among people.

Fungal Meningitis Outbreak. 7 Dead. 64 Sick.

Rare Fungal Meningitis Outbreak Rises; 7 Dead, 64 Sick

A rare fungal meningitis that has been linked to spinal steroid injections has killed seven people and sickened 64 across nine states, health officials said today.
The latest cases were confirmed in Minnesota and Ohio, according to figures posted on the Centers for Disease Control and Prevention's website.
The other states with reported cases are Tennessee, Florida, North Carolina, Indiana, Michigan, Virginia and Maryland.
The outbreak of aspergillus meningitis has been linked to spinal steroid injections, a common treatment for back pain. A sealed vial of the steroid, called methylprednisolone acetate, was found to contain fungus, according to the U.S. Food and Drug Administration.
"FDA is in the process of further identifying the fungal contaminate," said Dr. Ilisa Bernstein, acting director of the FDA's Center for Drug Evaluation and Research Office of Compliance. "Our investigation into the source of this outbreak is still ongoing."
The steroid came from the New England Compounding Center in Framingham, Mass., a specialty pharmacy that has recalled three lots of the drug and shut down operations. Calls to the pharmacy were not immediately returned and their website is down.
Roughly 75 clinics in 23 states that received the recalled lots have been instructed to notify all affected patients.
"If patients are concerned, they should contact their physician to find out if they received a medicine from one of these lots," said Dr. Benjamin Park of the U.S. Centers for Disease Control and Prevention, adding that most of the cases occurred in older adults who were healthy aside from back pain.
Meningitis affects the membranous lining of the brain and spinal cord. Early symptoms of fungal meningitis, such as headache, fever, dizziness, nausea and slurred speech, are subtler than those of bacterial meningitis and can take nearly a month to appear. Left untreated, the inflammatory disease can cause permanent neurological damage and death.
"Fungal meningitis in general is rare. But aspergillus meningitis -- the kind we're talking about here -- is super rare and very serious," said Dr. William Schaffner, president of the National Foundation for Infectious Diseases and chairman of preventive medicine at Vanderbilt University Medical Center in Nashville, Tenn. "There's no such thing as mild aspergillus meningitis."
The disease is diagnosed with a lumbar puncture, which draws cerebrospinal fluid from the spine that can be inspected for signs of the disease. Once detected, it can be treated with high doses of intravenous antifungal medications.
"Treatment could be prolonged, possibly on the order of months," said Park, adding that the IV treatment would require a hospital stay.
Unlike bacterial and viral meningitis, fungal meningitis is not transmitted from person to person and only people who received the steroid injections are thought to be at risk.
The FDA has, however, advised health providers to stop using any product made by the New England Compounding Center during the investigation.

CDC: Death toll in rare fungal meningitis outbreak linked to steroid injections rises to 7

ATLANTA — Health officials say the death toll in a rare fungal meningitis outbreak across several states has risen to seven.
In updated figures posted to its website Saturday, the Centers for Disease Control and Prevention says the outbreak has spread to more than 60 people across nine states.
Minnesota and Ohio are the two latest states to report confirmed cases linked to a steroid produced by a specialty pharmacy in Massachusetts. The steroid has been recalled, and health officials have been scrambling to notify anyone who may have been injected with it.
The New England Compounding Center has said it is cooperating with health investigators to determine the source of the infections.

    Super Bug Outbreak Alert! 8-19-2011

    Scientists Search for Kryptonite to Defeat Drug-Resistant Super Bugs

    Many Believe that a Supervirus will be the Doom of Mankind

    This theory has been gaining more popularity lately, as many new drug-resistant superbugs have been not only been killing people, but birds, fish and even pigs across the globe.


    With birds falling from the sky while people are dying in modern hospitals from mysterious staff infections, its no wonder that people's imaginations are running amok. While religious doomsday sayers preach about biblical plagues many heathen conspiracy theorists believe the diseases were manufactured in government labs to implement some sort of population reduction.

    Meanwhile, public health officials are worried about the rising number of new drug resistant superbugs, as well as of the overuse of antibiotics, hand sanitizers and home disinfectants. The overuse of atibiotic drugs and cleaners could make these bacteria resistant to them, so that they would no longer work for even curing minor viral infections, including flu, coughs, colds and sore throats.  

    Fortunately, a team of Canadian scientists discovered that specific mixtures of antimicrobial agents presented in lipid (fatty) mixtures can significantly boost the effectiveness of those agents to kill the resistant bacteria.

    Thank God these "Super bugs," which can cause wide-spread disease and may be resistant to most, if not all, conventional antibiotics, still have their weaknesses.

    According to Richard Epand, Ph.D. from the Department of Biochemistry and Biomedical Science at McMaster University in Hamilton, Ontario, Canada, a researcher involved in the study, "This study may contribute to overcoming the lethal effects of drug resistant bacteria that is becoming an increasing clinical problem, particularly in hospitals."

    Their discovery came when Epand and colleagues conducted experiments using groups of mice infected with lethal doses of multidrug-resistant Escherichia coli (E. coli). The rresearchers then treated the mice with conventional drug combinations or drug combinations encapsulated in lipid mixtures. They found that certain lipid mixtures caused the drugs to act together in a synergistic manner. In this mano, the drugs were far more effective in increasing the survival rate of the lab rats, as they overcame the cellular mechanisms used by these bacteria to defeat therapeutic agents.

    This study also demonstrated a new use of the premier family of antimicrobial agents called oligo-acyl-lysyls, which have the potential to be combined with other drugs to yield a platform for other specific applications.

    Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal said, "as we've seen in the recent E. coli outbreak in Germany, bacteria can mutate to become super bugs that resist antibiotics. Thanks to this new, lipid-based antibiotic therapy, multidrug-resistant bacteria may begin to look more like Jimmy Olsen and a lot less like Superman."...

    What do you think? Do you think science will outsmart bacteria and viruses? Do you believe we will someday conquer disease? Maybe enable people to live longer? Please leave your comment bellow!

    Superbug frightening for frail patients in Los Angeles, Utah and beyond

    Published: Monday, March 28, 2011 12:25 p.m. MDT
     
    A "superbug" that outsmarts multiple types of antibiotics in the medical arsenal has infected more than 350 patients in Los Angeles-area facilities. And that has health officials nationwide worried. A study of the issue by the LA. County Department of Public Health will be presented in Dallas next week at the annual meeting of the Society for Healthcare Epidemiology of America.
    ABC News reported this weekend that carbapenem-resistant Klebsiella pneumoniae, or CRKP, had been seen hundreds of times there between June and December of 2010. Most of the patients were elderly. The report quoted study author Dr. Dawn Terashita, medical epidemiologist, as saying most of the patients were elderly, they were often on ventilators and they are apt to have been staying at a facility for a long time.
    The Centers for Disease Control and Prevention began tracking CRKP across the country in 2009. Officials there say it is harder to treat than MRSA, methicillin-resistant Staphylococcus aureus. It has also been confirmed in most of the states, including Utah, according to a map made by the CDC.

    The CDC describes Klebsiella as a type of gram-negative bacteria that normally is found living harmlessly in human intestines. It can cause a variety of infections, most of them associated with healthcare settings, including pneumonia, bloodstream infections, wound or surgery-site infections and meningitis. That's determined by how it enters a patient, so infection gained through respiration becomes pneumonia, while that in a wound becomes a bloodstream infection, for example.

    So-called "superbugs" occur when bacteria mutate to the point that antibiotics previously effective against them no longer are. "Superbug" and "multiresistant" are sometimes used interchangeably.

    The ABC report emphasizes that healthy people are not endangered by the bacteria, but said it can be lethal to those who are ill or frail....

    Superbug outbreak declared at Kingston hospital

    Aug 17, 2011 – 9:01 AM ET
    KINGSTON, Ont. — An Ontario hospital has declared a facility-wide outbreak of the drug-resistant superbug C. difficile, after 12 new cases were reported in the last 30 days.

    The Kingston General Hospital said in a statement that staff are working to contain the outbreak and stop further spread of the hospital-acquired infection.

    The hospital is urging people not to come to the hospital if they are feeling unwell, and advising visitors to be diligent in washing their hands to prevent spreading the disease.

    C. difficile spreads through contact with fecal matter and is especially difficult for the elderly and those with existing health conditions to handle. Symptoms include diarrhea, loss of appetite, nausea and abdominal pain.

    Ontario has struggled to contain the superbug, which is responsible for at least 24 deaths since May.

    Hospitals in the Niagara area, Guelph and Orangeville have all grappled with outbreaks.

    Superbug alert after hospital patient dies

    Mary Ann Benitez
    Wednesday, August 17, 2011



    Infection control measures were rushed in at a ward in Caritas Medical Centre after an elderly man with a hospital-acquired superbug infection died. 
    Two other patients were found to be carriers of the superbug and were in fair condition in isolation last night.

    The Kowloon hospital said a 74-year-old man with pneumonia and acute renal failure was admitted to a 50-bed medical ward at the hospital in Sham Shui Po on July 29.

    The patient was put on a catheter, but there was no information on other treatment he received.

    He was confirmed to be suffering from Vancomycin-resistant enterococci (VRE) urinary tract infection on Sunday.

    He died of renal failure yesterday morning.

    The case is being investigated by the Hospital Authority and the Centre for Health Protection.

    The hospital is testing patients who stayed in the same ward with the man over the same period and have found two male patients aged 74 and 76 to be VRE carriers after rectal swabs.

    Both men were earlier admitted to hospital for pneumonia.

    "This is contact precaution," a hospital spokeswoman said. "They have no infection signs, just carriers."
    Both patients are being monitored and are in fair condition in isolation.

    The hospital has stepped up handwashing and alerted staff to keep to a high standard of disease control and ensure proper use of antibiotics, including Vancomycin, and management of VRE carriers.

    Tests are pending on other patients who may have been infected, the spokeswoman said, adding that no members of hospital staff are being tested for the superbug infection.

    A specialist in infectious diseases, Lo Wing-lok, said he is not surprised with the cluster of superbug infections.
    This is because Caritas serves "a very aged area and there are so many elderly patients who are chronically ill and staying in hospital for a long time."

    VRE is an opportunistic bacteria found in the intestines which usually preys on the elderly and patients with low levels of immunity.

    Lo said a urinary catheter usually serves as "a highway for the bacteria to move from the bowels to the urinary tract."

    Elderly men "have big prostate glands and do not pass water as well as young people" so are prone to urinary tract infection when they use catheters for too long.

    "I understand how such outbreaks can happen where elderly patients are being admitted and stay for a long time, where it is usually crowded and staff are stretched to the limit. We can only blame the system," he said.

    New superbug is on the rise in our hospitals

    WORRY: More patients hit by CRE


    By Clodagh Sheehy
    Thursday August 18 2011

    Four new cases of a hospital superbug, which can cause dangerous infections in vulnerable patients, have been detected here in the past month.

    The bug, which is resistant to some antibiotics, can hit the kidneys, wounds and blood of patients.

    The Health Protection Surveillance Centre (HPSC) is to review all critical care units to assess the prevalence of the infection.

    The bug CRE (Carbapenem Resistant Enterobacteriaceae) lives in the bowel and five cases were detected in Irish hospitals earlier this year.

    The independent European journal Eurosurveillance has now confirmed that "as of July 20, 2011 an additional four cases" of the superbug had been found.

    The nine cases are the first reported cases of this strain of CRE in Ireland and the HPSC has described the outbreak as "dramatically changing the epidemiology of CRE in Ireland".

    CRE cases have been notifiable in Ireland since March but to date there has been no national compulsory screening programme.

    Five cases were detected between March and Junein patients who had all undergone complex stomach surgery.

    COMPLICATIONS
    One patient later died from "complications of a gastro- intestinal haemorrhage not related to infection".

    The four new cases were found in St Vincent's hospital in Dublin and the Mid Western Regional hospital in Limerick, St John's Hospital, Ennis General Hospital and Nenagh General Hospital.

    None of the patients had been treated at a healthcare facility outside the country in the previous 12 months and so had not picked up the bug abroad.

    The superbug was first found in Turkey three years ago and since then outbreaks have been reported in France, Germany and the UK, Argentina, Lebanon, Israel Morocco and Tunisia.

    The HPSC has announced plans for a new study to detect how common the bug is in hospital intensive care units in this country.

    Understanding Swine Flu

    Understanding Swine Flu Outbreak: Questions and Answers

    By John Lauerman

    April 27 (Bloomberg) -- Swine flu, a virus that normally infects pigs, has been detected in people in Mexico, the U.S., New Zealand, Canada, and the U.K. Health officials around the world are checking to see whether infections have occurred in their countries, and readying measures to prevent its spread.

    Here are answers to some frequently asked questions about swine flu. The information is drawn from the data released by the World Health Organization in Geneva and the U.S. Centers for Disease Control and Prevention in Atlanta.

    Q: What is swine flu? A: Influenza is a virus that infects people, birds, pigs and other animals such as ferrets. Swine flu, or swine influenza, is a form of the virus that normally infects pigs. There are many forms of flu, and the different varieties have the ability to exchange genes with one another. The form of flu that originated in Mexico is a genetic mixture of viruses that have been seen in pigs, birds and people. It’s being called a swine flu because the overall structure of the virus is of the type that affects pigs, said Keiji Fukuda, a WHO official.

    Q: How do people catch swine flu? A: Studies are still ongoing on how this particular swine flu is transmitted. Flu is generally transmitted through the respiratory tract. Droplets of infected body fluids can carry flu when people cough or sneeze. Studies indicate that masks called N95 respirators that, when properly used, filter germs from the breath and hamper the spread of flu. Neither contact with pigs nor eating pork has been linked to the spread of the flu, Fukuda said today. Still, health researchers are working to establish that the virus is spreading from person-to-person.

    Q: What are the symptoms of swine flu? A: About one to four days usually elapse between the time a person is infected and the onset of symptoms. Influenza normally causes symptoms such as coughing, sneezing, headaches and body aches, fever, chills, and sometimes vomiting and diarrhea. Swine flu causes the same symptoms, and may be difficult to distinguish from other strains of flu and respiratory illnesses. Severe cases of flu that lead to death are normally seen in very young and very old people whose immune systems are too weak to fight off the virus. Adults with severe illness may also have difficulty breathing, dizziness, confusion, or severe vomiting and diarrhea.

    Q: How can I tell if my child is sick? A: Children who are breathing abnormally fast or slowly may have respiratory illness. Bluish skin indicates a need for quick attention. Children who are abnormally sluggish and sleepy, irritable, or have fever or rash may also need attention.

    Q: Have there been outbreaks of swine flu before? A: Yes. Health officials said in 1976 that an outbreak of swine flu in people might lead to a pandemic. Widespread vaccination was carried out in the U.S. before experts determined that the virus was not dangerous enough to cause a pandemic. Swine flu occasionally infects people in the U.S. without causing large outbreaks. From 2005 through January 2009, there were 12 reported swine flu cases in the U.S. None of them caused deaths.

    Q: Why are health officials concerned about the outbreak of swine flu? A: When flu viruses mix their genes with one another, they can take on new forms. New flu viruses are harder for the immune system to defend against. With little or no opposition from the immune system, they can grow quickly and invade many tissues and organs. They may also set off a harmful immune overreaction in the body, called a “cytokine storm,” that may be lethal in itself. The swine flu virus from Mexico may have the ability to spread quickly and kill people, possibly causing a worldwide pandemic, according to the World Health Organization. Researchers are conducting studies right now to determine how easily the virus spreads in people and how dangerous it is.

    Q: What’s a flu pandemic? A: Flu pandemics occur when new influenza viruses emerge that spread quickly and few people have immunity to them. While influenza viruses were only discovered about a century ago, researchers believe flu pandemics hit about twice or three times each century. Some pandemics are relatively mild, killing just a few million people globally. The most severe flu pandemic on record was the 1918 Spanish Flu, and researchers estimate it killed about 50 million people around the world.

    Q: Are there any similarities between the swine flu and earlier pandemic viruses? A: Flu viruses are classified by two proteins on their surface, called H for hemagglutinin and N for neuraminidase. Both the swine flu found in Mexico and the 1918 Spanish Flu viruses are of the H1N1 subtype. Both viruses appear to have originated in animals; researchers believe the Spanish flu spread to people from birds. The two viruses are not identical, and there are still many genetic differences between them that researchers are studying.

    Q: Do all H1N1 viruses cause pandemics? A: Not all H1N1 viruses cause pandemics. H1N1 descendants of the Spanish Flu virus continue to circulate in people and sometimes cause outbreaks of seasonal flu.

    Q: Is there a vaccine against the swine flu from Mexico? A: Flu vaccines generally contain a dead or weakened form of a circulating virus. The vaccine prepares the body’s immune system to fend off a true infection. For the vaccine to work, it must match the circulating, “wild-type” virus relatively closely. There is no vaccine currently that exactly matches the swine flu. However, if the virus is sufficiently similar to circulating forms of H1N1 flu that are included in current vaccines, they may offer some limited protection from swine flu. While U.S. health officials are investigating this, the possibilities for this protection are poor, they said yesterday on a telephone call.

    In addition, millions of people in the U.S. were vaccinated against swine flu in 1976. While that was not the same strain of flu as the one from Mexico, people who got the 1976 vaccine may get some limited protection from the currently circulating virus. Health officials may do some research on this issue as well.

    Vaccine makers have contacted the World Health Organization about obtaining samples of the virus needed to make a vaccine. Making flu vaccine can take three to six months, depending on the type of manufacturing used.

    Q: Are there drugs that treat swine flu? A: Roche Holding AG’s Tamiflu and GlaxoSmithKline Plc’s Relenza both have activity against swine flu. The U.S. has released its stockpile of Tamiflu to treat people with swine flu. Flu viruses sometimes develop resistance to antiviral drugs. The human form of H1N1 that’s currently circulating is resistant to Roche’s Tamiflu (not Relenza). If the two viruses were to exchange genes, the swine flu might become resistant, too.

    Q: How else can I protect myself from swine flu? A: Personal hygiene measures, such as avoiding people who are coughing or sneezing and frequent hand-washing, may prevent flu infection. Those who aren’t health professionals should avoid contact with sick people, or those who are coughing or sneezing. People who get sick with flu symptoms should stay home. Studies have suggested that closing schools, theaters, and canceling gatherings in the early stages of a pandemic can limit its spread. Such measures would likely take place if health officials determine that the virus is spreading quickly enough and is deadly enough to cause a pandemic.

    Swine Flu - Utah Public Health Officials Order Supplies From Strategic National Stockpile

    While no cases of swine influenza (H1N1) have been documented in Utah, public health officials are taking a proactive approach in order to be prepared for a possible outbreak. As of this afternoon, the US Centers for Disease Control and Prevention (CDC) is reporting 20 cases of swine flu in five states - California, Texas, Ohio, Kansas and New York. In addition, CDC along with the World Health Organization is assisting the Mexican government in tracking an outbreak caused by the same swine influenza virus.

    Earlier today, the United States Department of Health and Human Services declared a Public Health Emergency as a consequence of the outbreak. The declaration will assist public health officials in responding to the outbreak.

    As a precaution, the UDOH has initiated the process of ordering 25 percent of the state's pro-rated share of anti-viral medications and other supplies from the Strategic National Stockpile. State and local health officials are coordinating their response with Gov. Jon Huntsman, the Utah Department of Public Safety, as well as other federal government partners.

    "Even though we don't have any cases in Utah, this is still a situation where we need to be on high alert, but not to panic," said Utah Department of Health Executive Director Dr. David Sundwall. "The UDOH has increased its disease surveillance efforts and asks that all physicians be on the lookout for patients who may be exhibiting flu-like symptoms and report them to public health officials."

    Symptoms may include fever, body aches, runny nose, sore throat or cough; some patients may also have nausea, vomiting or diarrhea. The UDOH recommends people who have flu symptoms remain home and limit contact with others unless the severity of illness requires medical care. Physicians who see these patients should collect specimens, such as a nasal swab, and submit them for testing at the Utah Public Health Laboratory.

    It's also important for individuals to realize the swine flu virus is not transmitted by food and that you cannot get swine flu from eating pork products.

    "We recognize that it is difficult to foresee the extent to which Swine Influenza A will affect our local communities," said Lloyd Berentzen, Health Officer for the Bear River Health Department and President of the Utah Local Health Officers Association. "Because of this uncertainty it is important that we ramp up our awareness and preparedness practices. We will do all we can to protect our communities and empower individuals to know what they can do."

    Public health officials also stressed the importance of the public's cooperation and participation in preventing an outbreak and offered the following tips:
    As is the case with any respiratory illness, people who are sick should stay home from work or school to avoid spreading their infection,

    Avoid close contact with people who are coughing or ill,

    Cover your cough with your shirt sleeve,

    If you are sick, avoid touching your eyes, nose and mouth if possible,

    Everyone should wash their hands frequently.
