Swine Influenza (H1N1) Questions and Answers

What is swine flu?

Swine Influenza, also called swine flu, is a respiratory disease of pigs caused by type A influenza viruses (H1N1). Outbreaks of swine flu happen regularly in pigs. People do not normally get swine flu, but human infections can and do happen. Most commonly, human cases of swine flu happen in people who are around pigs but it's possible for swine flu viruses to spread from person to person also.

Is swine flu the same as seasonal flu?

No. Seasonal flu is a contagious respiratory illness caused by human influenza viruses. It can cause mild to severe illness and at times can lead to death. Human flu viruses change a little bit every year which is why people can get sick from the flu more than once. It is also why a new flu vaccine is produced each year; the vaccine must be made to protect against the particular viruses circulating that year.

Is this the same as the bird flu (avian flu) that has been in the news in recent years?

No. There are many different types of influenza viruses. The bird flu virus that has been watched closely is categorized as influenza A (H5N1), and is transmitted primarily among birds. This virus has not been found in the United States.

Is swine flu the same as pandemic flu?

Rarely, an influenza virus undergoes a major change that results in a completely new virus. If the new virus spreads easily from person to person it is called a pandemic. All human influenza pandemics in the past have been caused by human influenza viruses. Swine flu viruses have caused human infections before without becoming a pandemic flu virus. It is unknown whether this current swine flu A (H1N1) virus could become a pandemic.

Are there people infected with swine flu in the U.S.?

The breakdown of the number of laboratory-confirmed cases by country is given in the following table and map.

Influenza pandemic alert raised to phase 6

11 June 2009 -- On the basis of available evidence and expert assessments of the evidence, the scientific criteria for an influenza pandemic have been met. The Director-General of WHO has therefore decided to raise the level of influenza pandemic alert from phase 5 to phase 6. "The world is now at the start of the 2009 influenza pandemic," she said at a press conference today.

What is phase 6? What about severity?

Should I keep my child home from school as a precaution?

No. Parents do not need to keep otherwise healthy children home from school unless directed to do so by local school and health officials.

Children who are ill should not attend school. In this case, monitor your child for influenza-like symptoms, including fever, body aches, runny nose, sore throat, nausea, vomiting or diarrhea, and keep your child home if they are sick. You may want to contact their health care provider, particularly if symptoms are severe. Be sure to tell your doctor if you have recently traveled, especially to states in the U.S. or to other countries where swine flu has already been been confirmed, including California, Kansas, New York City, Ohio, Texas and Mexico. Your health care provider will determine whether influenza testing or treatment is needed.

How are people getting sick from swine flu?

CDC has determined that this H1N1 swine flu virus is spreading from person to person. Spread from person to person is thought to occur in the same way as seasonal flu, mainly through coughing or sneezing of infected people. However, at this time, it not known how easily the swine flu virus spreads between people.

What are the signs and symptoms of swine flu in people?

The symptoms of swine flu in people are similar to the symptoms of regular human flu and include fever greater than 100°F, cough, sore throat, body aches, headache, chills and fatigue. Some people have reported diarrhea and vomiting associated with swine flu. Like seasonal flu, swine flu can vary in severity from mild to severe, and may cause a worsening of underlying chronic medical conditions. The severity of illness from the current swine flu strain is not yet clear.

Can swine flu be treated?

Yes. This swine flu virus (H1N1) is susceptible to certain antiviral drugs used to treat flu infections (oseltamivir, or Tamiflu, and zanamivir, or Relenza). For treatment, antiviral drugs work best if started soon after getting sick (within 2 days of symptoms). If you become ill and are diagnosed with influenza, your doctor can determine if you should take antiviral drugs.

Should I ask my doctor for a prescription anti-flu drug?

No. Antiviral drugs are usually used to treat people who are at risk for developing life-threatening complications from the flu. There is no reason to routinely ask for one of these drugs to keep at home, or to take them just as a precaution. Over-use could result in limited supplies for those who need it most. In addition, over-use of antiviral drugs has been known to lead to flu viruses becoming resistant to the drugs. All drugs, including antivirals, can cause side effects and should only be used when necessary under the direction of a health care provider.

How long can an infected person spread swine flu to others?

People with H1N1 swine flu infection should be considered potentially contagious as long as they are symptomatic or possibly for up to 7 days following illness onset. Children, especially younger children, might potentially be contagious for longer periods.

Is there a vaccine against swine flu?

There is currently no human vaccine against H1N1 swine flu. It is not known whether the current human flu vaccine provides partial protection against swine flu. CDC has already begun development of a vaccine for swine flu, but this will not be available for months.

Can I get tested for H1N1 swine flu?

The New York State Department of Health has provided guidance to health care providers and hospitals throughout the state regarding who should be tested for swine flu and what specimens to collect. If you are severely ill or worried about your symptoms, contact your health care provider who will determine whether testing is necessary.

What can I do to protect myself from getting sick?

There are everyday actions that can help prevent the spread of germs that cause respiratory illnesses like influenza. Take these everyday steps to protect your health:

•Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
•Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hand cleaners are also effective.
•Try to avoid close contact with sick people.
•Avoid touching your eyes, nose or mouth. Germs spread this way.
•If you get sick with influenza, CDC recommends that you stay home from work or school and limit contact with others to keep from infecting them.

What should I do if I get sick?

If you become ill with influenza-like symptoms, including fever, body aches, runny nose, sore throat, nausea, vomiting or diarrhea, you may want to contact your health care provider particularly if you are worried about your symptoms. Be sure to tell your doctor if you have recently travelled, especially to states in the U.S. or to other countries where swine flu has already been confirmed. Your health care provider will determine whether influenza testing or treatment is needed.

If you are sick, you should stay home and avoid contact with other people as much as possible to keep from spreading your illness to others.

Should I avoid travel to other countries or areas of the United States where H1N1 swine flu has been identified?

At this time, CDC recommends that U.S. travelers avoid all nonessential travel to Mexico. Changes to this recommendation will be posted at http://wwwn.cdc.gov/travel/.
