how the flu virus spreads
The flu vaccination should protect you from getting the flu. The flu vaccine is usually 70% effective.
stuck in a room or a house for example when i was sick with swine flu i has to stay in a isolated room( closed in room)
no you shouldn't the flu is contagious you wouldn't want to get your child sick unless he has the shot for that flu
You have to wait until your better then you get the flu shot
The flu shots are to prevent the flu, not to treat the flu. It will not be necessary to get a flu shot after you have had the flu, if you know what type of flu you had for sure (by lab testing). If you are not sure that it was the seasonal flu or another type of flu (like swine flu), then taking a vaccination will be a good idea to be sure you are protected for the other strains of flu. It will not hurt to take a flu shot for the same type of flu you had, and if the vaccine is for a different type, then you will have that added protection. You should usually wait until after the symptoms of active fever are gone before getting a flu shot, though. Flu shots work by exposing you to a small amount of weakened or dead viruses that cause a specific flu, or sometimes the vaccine will cover several (the seasonal flu vaccine usually contains three strains), so that your body can build immunity to them before being exposed to the full strength viruses in the environment. For the 2009 - 2010 flu season in the US, you are encouraged to get two vaccinations for the flu. One for the seasonal flu (it protects against three flu strains) and one for the A-H1N1/09 swine flu. If you have not had lab confirmation of the type of flu you already have had, then the CDC still recommends you get both vaccines.
Assuming the question is a typo for "Why do antibiotics not work on a flu?", the reason is quite simple. Influenza (Flu) is caused by a virus, not a bacteria or parasite. When you have an infection, and your doctor prescribes you antibiotics, they are working on a bacterial or parasitic infection, not a viral infection. Put quite simply, antibiotics are not effective whatsoever against viruses.
I should have stayed in a few more days with the flu because my symptoms relapsed when I returned to work.
