H1N1 flu (originally called swine flu) is a respiratory infection that can cause mild to severe symptoms. If you think that your child may have this virus, call your doctor.
Flu is usually spread by:
- Breathing in droplets after an infected person coughs or sneezes
- Touching a contaminated surface and then touching your eyes, nose or mouth
The virus can survive on surfaces and infect a person for several hours after being exposed to the surface.
Who is More at Risk
The main risk factor for getting H1N1 flu is contact with an infected person. Children younger than two years of age and children with chronic health conditions may be at greater risk for a severe form of flu. People younger than 25 years old are more likely to be affected by the virus. Older people may have developed immunity against the virus.
There is also a vaccine available for H1N1 and seasonal flu.

Diagnosis & Treatment at UVA Health Children's
Your child’s doctor will ask about your symptoms and medical history. In some cases, your doctor may take samples from your child’s nose or throat to confirm the diagnosis.
Talk with your doctor before giving your child any over-the-counter medications. Avoid giving your child aspirin. It can cause serious complications in children with certain infections.
Most people with the flu do not need antiviral medications. If your child has the flu, check with your doctor to see if they need antiviral medication. Antiviral medications do not cure the flu. They may help relieve symptoms and shorten the time that your child is sick. They must be taken within 48 hours of the first symptoms. If you give your child antivirals, closely monitor them for signs of unusual behavior.
