HHS Declares Public Health Emergency for Swine Flu

The Department of Health and Human Services today issued a nationwide public health emergency declaration in response to recent human infections with a newly discovered swine influenza A (swine flu) virus.

The formal declaration of a Public Health Emergency (PHE) is a tool that facilitates HHS’ preparation and mobilization for disasters and emergencies. For example, PHEs were recently declared for flooding in North Dakota, the Inauguration, and several 2008 hurricanes.

Today’s declaration, made under section 319 of the Public Health Service Act, will help HHS prepare for prevention and mitigation activities by enabling Food and Drug Administration (FDA) emergency use authorizations of drugs, devices, or medical tests under certain circumstances.

Specifically, today’s PHE will enable the FDA to review and issue emergency use authorizations (EUAs) for the use of certain laboratory tests to help detect the newly discovered strain of influenza and for the emergency use of certain antivirals.

“HHS is taking these steps today to be proactive in responding to this new influenza virus by offering national tools in support of community-led preparedness and response efforts,” Acting HHS Secretary Charles Johnson said. “The declaration allows us the flexibility, while we learn more about the virus and its impact in the United States, to take additional steps to fully mobilize our prevention, treatment and mitigation capabilities should those actions become necessary.”

In addition to the declaration, HHS leaders are working together across operating divisions to coordinate response to the swine flu outbreak. For example, the FDA, the National Institutes of Health, and the Centers for Disease Control and Prevention are working together to develop a vaccine precursor that could be used to develop a vaccine for this swine flu virus.

To date, there have been 20 confirmed cases of swine Influenza A (swH1N1) in California, Texas, Kansas, New York, and Ohio. No deaths in the U.S. have been reported due to the illness. Additional cases of the virus have been confirmed in Mexico and Canada.

Swine flu is a respiratory disease of pigs caused by type A influenza that regularly causes outbreaks of influenza among pigs. Swine flu viruses do not normally infect humans; however, human infections with swine flu do occur, and cases of human-to-human spread of swine flu viruses have been documented.

The public health emergency declaration is available at www.hhs.gov/secretary/phe_swh1n1.html. For information on swine flu, visit www.cdc.gov/swineflu.

Overview

In response to the exponential increase in international travel and trade, and emergence and reemergence of international disease threats and other health risks, 194 countries across the globe have agreed to implement the International Health Regulations (2005) (IHR). This binding instrument of international law entered into force on 15 June 2007.

The stated purpose and scope of the IHR are "to prevent, protect against, control and provide a public health response to the international spread of disease in ways that are commensurate with and restricted to public health risks, and which avoid unnecessary interference with international traffic and trade." Because the IHR are not limited to specific diseases, but are applicable to health risks, irrespective of their origin or source, they will follow the evolution of diseases and the factors affecting their emergence and transmission. The IHR also require States to strengthen core surveillance and response capacities at the primary, intermediate and national level, as well as at designated international ports, airports and ground crossings. They further introduce a series of health documents, including ship sanitation certificates and an international certificate of vaccination or prophylaxis for travelers.

Finally, this second edition includes a new foreword and the Health Part of the Aircraft General Declaration (as revised by the International Civil Aviation Organization), as well as Appendices listing States Parties to the IHR and reservations, objections and declarations received from States Parties.

Is it safe to travel?

7 May 2009 (updated from 1 May 2009)

Is it safe to travel?

WHO is not recommending travel restrictions related to the outbreak of the influenza A(H1N1) virus. Today, global travel is commonplace and large numbers of people move around the world for business and leisure. Limiting travel and imposing travel restrictions would have very little effect on stopping the virus from spreading, but would be highly disruptive to the global community.

Influenza A(H1N1) has already been confirmed in many parts of the world. The global response now focuses on minimizing the impact of the virus through the rapid identification of cases, and providing patients with appropriate medical care, rather than on stopping its spread internationally.

Although identifying signs and symptoms of influenza in travellers can help track the path of the outbreak, it will not reduce the spread of influenza, as the virus can be transmitted from person to person before the onset of symptoms.

Scientific research based on mathematical modelling shows that restricting travel would be of limited or no benefit in stopping the spread of disease. Historical records of previous influenza pandemics, as well as experience with SARS, validate this.

Does WHO recommend screenings at country entry and exit points to detect if ill people are travelling?

No. We do not believe entry and exit screenings would work to reduce the spread of this disease. However country-level measures to respond to a public health risk are the decision of national authorities, under the International Health Regulations 2005.

Countries that adopt measures that significantly interfere with international traffic (e.g. delaying an airplane passenger for more than 24 hours, or refusing country entry or departure to a traveller) must provide WHO with the public health reasoning and evidence for their actions. WHO will follow up with all of its Member countries on such matters.

Travellers should always be treated with dignity and respect for their human rights.

How can I protect myself from influenza A(H1N1) when I am travelling?

People who are ill should delay travel plans. Returning travellers who become ill should contact their health care provider.

Travellers can protect themselves and others by following simple prevention practices that apply while travelling and in daily life.

Are some people more at risk?

1 May 2009
Are some people more at risk?

More study is needed to determine if some populations (i.e. younger or older people, or people with other medical conditions) could be affected by the outbreak, of if they are at higher risk for severe illness. WHO recommends that everyone take precautions to prevent the spread of infection.

Are there any special recommendations for pregnant women?

Yes, they are vulnerable. Like everyone, they should take all the necessary precautions.

What can I do to protect myself from catching influenza A(H1N1)?

The main route of transmission of the new influenza A(H1N1) virus seems to be similar to seasonal influenza, via droplets that are expelled by speaking, sneezing or coughing. You can prevent getting infected by avoiding close contact with people who show influenza-like symptoms (trying to maintain a distance of about 1 metre if possible) and taking the following measures:

  • avoid touching your mouth and nose;
  • clean hands thoroughly with soap and water, or cleanse them with an alcohol-based hand rub on a regular basis (especially if touching the mouth and nose, or surfaces that are potentially contaminated);
  • avoid close contact with people who might be ill;
  • reduce the time spent in crowded settings if possible;
  • improve airflow in your living space by opening windows;
  • practise good health habits including adequate sleep, eating nutritious food, and keeping physically active.

What about using a mask? What does WHO recommend?

If you are not sick you do not have to wear a mask.

If you are caring for a sick person, you can wear a mask when you are in close contact with the ill person and dispose of it immediately after contact, and cleanse your hands thoroughly afterwards.

When and how to use a mask?

If you are sick and must travel or be around others, cover your mouth and nose.

Using a mask correctly in all situations is essential. Incorrect use actually increases the chance of spreading infection.

How do I know if I have influenza A(H1N1)?

You will not be able to tell the difference between seasonal flu and influenza A(H1N1) without medical help. Typical symptoms to watch for are similar to seasonal viruses and include fever, cough, headache, body aches, sore throat and runny nose. Only your medical practitioner and local health authority can confirm a case of influenza A(H1N1).

What should I do if I think I have the illness?

If you feel unwell, have high fever, cough or sore throat:

  • stay at home and keep away from work, school or crowds;
  • rest and take plenty of fluids;
  • cover your nose and mouth when coughing and sneezing and, if using tissues, make sure you dispose of them carefully. Clean your hands immediately after with soap and water or cleanse them with an alcohol-based hand rub;
  • if you do not have a tissue close by when you cough or sneeze, cover your mouth as much as possible with the crook of your elbow;
  • use a mask to help you contain the spread of droplets when you are around others, but be sure to do so correctly;
  • inform family and friends about your illness and try to avoid contact with other people;
  • If possible, contact a health professional before traveling to a health facility to discuss whether a medical examination is necessary.

What should I do if I need medical attention?

  • If possible, contact your health care provider before traveling to a health facility, and report your symptoms. Explain why you think you have influenza A (H1N1) (e.g. if you have recently traveled to a country where there is an outbreak in people). Follow the advice given to you.
  • If you cannot contact your health care provider before traveling to a health facility, tell a health care worker of your suspicion of infection immediately after arrival at the clinic or hospital.
  • Cover your nose and mouth during travel.

Should I go to work if I have the flu but am feeling OK?

No. Whether you have influenza A(H1N1) or a seasonal influenza, you should stay home and away from work through the duration of your symptoms. This is a precaution that can protect your work colleagues and others.

Can I travel?

If you are feeling unwell or have symptoms of influenza, you should not travel. If you have any doubts about your health, you should check with your health care provider.

Use of antiviral drugs against influenza A(H1N1)

5 May 2009

For what purposes can antiviral drugs be used against influenza A(H1N1)?

So far most people who have contracted the new A (H1N1) virus have experienced influenza-like symptoms (such as sore throat, cough, runny nose, fever, malaise, headache, joint/muscle pain) and recovered without antiviral treatment.

Antiviral drugs may reduce the symptoms and duration of illness, just as they do for seasonal influenza. They also may contribute to preventing severe disease and death. Influenza A (H1N1) is a new virus and only a small number of people with the infection have been treated for it with antiviral drugs. WHO is in touch with public health authorities and clinicians in affected countries and is gathering information about how effective the drugs are.

To which antiviral drugs does this influenza virus respond?

There are two classes of antiviral drugs for influenza: inhibitors of neuraminidase such as oseltamivir and zanamivir; and adamantanes, such as amantadine and rimantadine. Tests on viruses obtained from patients in Mexico and the United States have indicated that current new H1N1 viruses are sensitive to neuraminidase inhibitors, but that the viruses are resistant to the other class, the adamantanes.

Could the virus become resistant to oseltamivir and zanamivir?

Resistance can develop to antiviral drugs used for influenza. Therefore, WHO and its partners are monitoring antiviral drug resistance.

Under what circumstances should antiviral drugs be administered?

Antiviral drugs are to be used according to national pandemic influenza preparedness plans. Public health authorities in some countries have decided to treat patients likely to have this disease as a part of public health measures.

Where antiviral drugs are available for treatment, clinicians should make decisions based on assessment of the individual patient's risk. Risks versus benefits should also be evaluated on a case by case basis.

What is WHO doing about getting antiviral drugs to countries as preparation for a pandemic?

WHO’s first priority is to provide an emergency stock of antiviral drugs to countries that have no or insufficient stock of the drugs and lack the capacity to procure these drugs themselves.

WHO is also working with Member States, donors and other groups that have stockpiles and are willing to share these with WHO for distribution to countries in need.

Which drug will be provided, and how much of it does WHO have available?

WHO had a global stockpile of approximately 5 million adult treatment courses of oseltamivir. Part of this stockpile has already been distributed through the WHO Regional Offices, which are handling allocation and distribution. WHO is currently distributing the remaining 3 million adult treatment courses of this stockpile to developing countries in need.

WHO continues to assess needs and to work with manufacturers to secure more donations of antivirals. More antiviral drugs will be distributed once these donations are received.

Which countries will receive the drug, and how will they be selected?

WHO has arranged the first deployment of antiviral drugs from the WHO stockpile to 72 countries. Priority was given to vulnerable countries, taking into consideration national manufacturing and procurement capacity. As necessary, other countries will be supported through regional office stockpiles.

What if the initial emergency deployment turns out to be inadequate?

WHO is in discussion with manufacturers regarding the potential need for scaling up production. It is WHO’s understanding that manufacturers have plans for producing large numbers of treatments quickly.

WHO will work on behalf of its Member States to secure further antivirals as needed, either through donations or purchase at the lowest possible price.

Preventing the spread of swine flu

Swine flu is a type of virus. It's named for a virus that pigs can get. People do not normally get swine flu, but human infections can and do happen. The virus is contagious and can spread from human to human. Symptoms of swine flu in people are similar to the symptoms of regular human flu and include fever, cough, sore throat, body aches, headache, chills and fatigue.


There are antiviral medicines you can take to prevent or treat swine flu. There is no vaccine available right now to protect against swine flu. You can help prevent the spread of germs that cause respiratory illnesses like influenza by

* Covering your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
* Washing your hands often with soap and water, especially after you cough or sneeze. You can also use alcohol-based hand cleaners.

* Avoiding touching your eyes, nose or mouth. Germs spread this way.
* Trying to avoid close contact with sick people.
* Staying home from work or school if you are sick.

When Swine Flu Hits Home

May 7, 2009, 4:53 pm
By Roni Caryn Rabin

After the first reports were published about swine flu among kids at St. Francis Preparatory High School in Queens, N.Y., where I live, a friend called me in a panic. Like many parents in the neighborhood, she was wondering if should keep her 10-year-old home from school.

Her house is a stone’s throw from the school, and mine is just a few miles from hers. “I’m scared,” she said. “One of his best friends has an older brother who goes to St. Francis.”


Fear was spreading faster than any virus could. Hand sanitizer was flying off the shelves. Then the wet wipes started to disappear. People walking through busy shopping areas, and even back streets, were wearing surgical masks, a habit many Asian immigrants had brought from China. I drove past one car with three mask-clad passengers in back.

When a girl at my daughter’s high school complained of a cough, the nurse gave her a choice of wearing a mask for the rest of the day – or going home. (Guess which she chose?) A lot of schoolkids stayed home; my friend told me of one parent who kept her children home for three days straight, and she lived in another borough.

“Tell them to wash their hands a lot,” was the only advice I could offer.

Reporters like myself often parachute into a region to report about a war or an election, but in this case, I just happen to live here. As journalists we often feel insulated by our status — we’re observers, after all, not participants — and on some unconscious level I think I believed my family and I were immune.

I was wrong.

The fear, meanwhile, fueled rumors. My friend Mary, who lives nearby, said her daughter stayed home from public school because she wasn’t feeling good one day. Her friends called that afternoon and asked if she was alright — they heard she had swine flu. Four of the kids in her class had been to Mexico over spring break, Mary’s daughter told her. The next day she corrected herself: only one had gone, “and that was to Jamaica.”

But it soon became clear it didn’t really matter who you knew or where they had been. The cat was out of the bag.

Some parents wanted the city to close all schools. But while St. Francis was shut down for a week and a half, a lot of students with nothing to do went to hang out in another enclosed gathering place … the mall.

When my own 15-year-old started coughing on Monday evening, I thought little of it. She’s pretty hardy and hadn’t missed a day of school since sixth or seventh grade. But when she woke up at 3 a.m. groaning loudly enough to wake me, I realized I’d been mistaken.

Sure, most years my daughter didn’t get the flu. But this was a novel strain. A new virus.

It was a miserable night — for our whole family, but mostly for her. She didn’t know what hit her. She was hot, and then she was cold. She shivered and coughed and groaned. Her throat was killing her, and by morning she was whispering.

“Will I have to go to the hospital?” she whispered.

“What if I gave it to my friends?”

“Will they shut down my school?”

I was worried, but not nearly as much as I would have been just a few days earlier. It was becoming fairly clear that young people in the United States weren’t dying of this flu strain, and most recovered without being hospitalized. If you weren’t very young or very old or pregnant, and you didn’t have diabetes, heart disease, H.I.V. or a compromised immune system, you probably wouldn’t even get a definitive diagnosis, and any available Tamiflu, the anti-flu drug, would be reserved for someone else.

An infectious disease specialist had told me on Friday that health officials were reassured by the way the outbreak was unfolding here. “If it weren’t for Mexico, this would be a page-15 story,” he’d said.

One thing is clear: we have good surveillance systems. Everyone was collecting data and phoning it in. When the high-school attendance office called, they didn’t just want to know my child was home sick, they wanted a list of symptoms: Did she have a cough? Sore throat? Fever? How high? Fifty kids in the school were absent, up from a daily average of 20 at most.

We had good information, and it was easily accessible to the public, not just through the traditional media but through the internet and twitter.

You could go to the Centers for Disease Control and Prevention Web site and find out whether face masks work (unclear), what you can do to minimize your risk (wash your hands, stay away from crowds, don’t touch your nose and face) and what you can do to help (sneeze into a tissue or your sleeve, stay home if you’re sick).

I still don’t know if my daughter actually has swine flu. The doctor who examined her was pretty sure she did — he called it A(H1N1), which somehow sounded less sinister. But there was no need for a test, and she was otherwise healthy and therefore not a candidate for Tamiflu anyway.

He listened to her lungs, proclaimed them all clear, and swabbed her throat for a strep culture, which was negative. The prescription was the usual for flu: Motrin, lots of fluids, rest. Oh, and ice-pops for the sore throat. We were to watch out for shortness of breath, worsening fever or unusual behavior.

She had completely lost her voice by then, so she borrowed my phone as we drove home and texted into it. “Throat like sandpaper stop 4 ice pops.”

By evening she was over the worst of it. She sat with us at dinner but had drunk so much tea she wasn’t really hungry. Every time she coughed we dove under the table. But I knew she was much better when, as she prepared for a world history exam, she had just one question, “What am I going to do about my chem test?”

And I have one lingering concern myself. If — and when — this rolls around again, in a fiercer form, will people think health officials are crying wolf and be blase about it? If this current flu does turn out to be much better than feared — and we all hope it does — the public health campaign must not stop. People need very clear explanations about why and how this virus could mutate into something worse.
