Swine Influenza (swine flu) Frequently Asked Questions
What is swine flu?
Swine Influenza, also called swine flu, is a respiratory disease of pigs caused by type A influenza viruses. 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 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?
No. 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. Swine flu is not the same as pandemic flu. 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 human infections with swine flu in the U.S.?
In late March and early April 2009, cases of human infection with swine influenza A (H1N1) viruses were first reported in San Diego County and Imperial County in Southern California and near San Antonio, Texas. CDC and local and state health agencies are continuing to investigate this situation. This same flu virus is being found in people in Mexico, and has also been confirmed in patients from Dickinson County, Kansas.

How are people getting sick from swine flu?
CDC has determined that this 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, 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. The few cases found in the United States so far have been mild.

Can swine flu be treated?
Yes. This swine flu virus 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 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.

Can I get swine influenza from eating or preparing pork?
No. Swine influenza viruses are not spread by food. You cannot get swine influenza from eating pork or pork products. Eating properly handled and cooked pork products is safe.

Is there a vaccine against swine flu?
There is currently no human vaccine against 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.

Is this swine flu in New York?
As of April 25th, 2009, swine flu cases have been found in southern California, near San Antonio, TX, and in Dickinson County, KS. There have been no cases confirmed in New York at this time, but there is suspicion that New York City has swine flu.

The New York City Department of Health and Mental Hygiene is investigating a current outbreak of flu-like illness at a high school located in the borough of Queens. Of 9 specimens taken from ill students at the school and tested by the NYCDOMHM, 8 specimens have tested probable for swine flu. These specimens were sent to CDC for confirmatory testing on April 25 and final results are expected sometime on April 26.
