the most common type of influenza. These strains have a high propensity for antigenic change resulting in mutations, partly because they can infect various animals where dual infections can occur, giving rise to new hybrid strains. The infections occur in epidemics, which may occur every 2-3 years and may vary in size and severity; perhaps the most important of the three types of influenza (A, B, and C).

Patient discussion about influenza A
Q. do i have a flu
A. What makes you think you have flu?
Do you have any of the signs or symptoms of it? (as listed here: http://en.wikipedia.org/wiki/Influenza#Symptoms_and_diagnosis or here: http://www.nlm.nih.gov/medlineplus/ency/article/000080.htm)
Q. Should I get a flu shot? I was wondering if one should get a flu shot. Does it even work and protect from the flu?
A. In general, anyone who wants to reduce their chances of getting the flu can get vaccinated. However, it is recommended that certain people should get vaccinated each year. They are either people who are at high risk of having serious flu complications or people who live with or care for those at high risk for serious complications. People who should get vaccinated each year are:
1. Children aged 6 months up to their 19th birthday
2. Pregnant women
3. People 50 years of age and older
4. People of any age with certain chronic medical conditions
5. People who live in nursing homes and other long-term care facilities
6. People who live with or care for those at high risk for complications from flu, including: Health care workers, Household contacts of persons at high risk for complications from the flu and Household contacts and out of home caregivers of children less than 6 months of age (these children are too young to be vaccinated)
Q. Can you get influenza after a dentist visit? I’ve been to the dentist yesterday and I woke up sick. Is it considered mal practice?
A. o..relax..first of all you can get the flu anywhere and anytime. Secondly- it takes more than a day to develop symptoms so yo probably got it from someone else. It’s not mal practice anyway, and stop thinking on how you can get money off your dentist :) here is a Southpark episode about it:More discussions about influenza A
