The Centers for Disease Control and Prevention CDC recommend an annual flu shot for everyone aged 6 months or older , barring certain rare exceptions.
A doctor can advise on individual needs. In some cases, however, a doctor may prescribe an antiviral medication. These drugs can shorten the duration of symptoms and reduce their severity. Doctors now consider H1N1 to be a flu strain that can occur in people and spread alongside seasonal flu viruses.
A person can catch it if they are in close contact with someone who has H1N1. People who work with swine may have a risk of contracting new types of flu or other diseases from animals. These are known as zoonotic diseases. Some people have a higher risk of flu, including H1N1, or having severe symptoms or complications. These individuals include :. If a doctor suspects that a person may have H1N1 or another type of flu, they may recommend a test to confirm the diagnosis.
The rapid influenza diagnostic test can help identify swine flu. However, this test can vary in effectiveness and may show a negative result when a certain influenza virus strain is present.
Most people do not need more than a rapid flu test, as treatment will be the same, regardless of the test outcome. Those whose work or lifestyle brings them into contact with swine and other animals should :.
Swine flu is a respiratory disease that transmits through droplets in the air and on surfaces. It is not possible to catch if from eating properly cooked pork. Another pandemic of H1N1 swine flu is much less likely now, as people have developed some degree of immunity. Before the — pandemic, there was no evidence that H1N1 had infected humans. Some pigs infected with influenza, however, may show no signs of illness at all. H1N1 and H3N2 swine flu viruses are endemic among pig populations in the United States and something that the industry deals with routinely.
Outbreaks among pigs normally occur in colder weather months late fall and winter , but can occur year round.
While H1N1 swine viruses have been known to circulate among pig populations since at least , H3N2 influenza viruses did not begin circulating among pigs in the United States until about The H3N2 viruses initially were introduced into the pig population from humans.
However, since then the H3N2 viruses circulating in pigs have changed. The H3N2 viruses circulating in pigs now are very different from the seasonal H3N2 viruses that circulate in humans. Just as there are influenza vaccines for people, there are specific swine influenza vaccines available for pigs. Skip directly to site content Skip directly to page options Skip directly to A-Z link.
