Is it possible for symptoms of H1N1 to show up the same day you suspect were exposed virus or is incubation period longer than just several hours?

The incubation period for the H1N1 virus, also known as the swine flu, typically ranges from 1 to 4 days. This means that it can take up to 4 days for symptoms to appear after exposure to the virus. It is unlikely for symptoms to show up the same day as exposure.

Symptoms of H1N1 can include:

If you think you may have been exposed to the H1N1 virus and are experiencing symptoms, it is important to contact a healthcare provider for evaluation and testing. Early diagnosis and treatment can help reduce the severity of symptoms and prevent complications.
