Para Flu Virus
Most often - yes.: Most people make it through the flu without antivirals or other medications.
Influenza is a viral respiratory infection that causes cough, fever, chills, sore throat, muscle aches and headache. While most healthy people suffer few complications from the flu, it can be deadly for pregnant women, babies and children, the elderly and those with weak immune systems. That's why it's so important to get the flu shot to protect yourself ...Read more
Yes: The flu can be caused by different strains of influenza virus. That's why a flu shot has more than one type of attenuated strain. It is possible to get the flu from different viruses, and a flu shot may not protect you from some different strain that you are infected from. So you could get the flu more than once, and from a different strain.
Unclear question: Immunity from flu vaccination starts waining in about 6 months.
Bacteria don't cause: Both colds and flu are caused by viruses. Flu hits like a ton of bricks--you're fine and an hour later you have a chill, then a fever and ache all over. Colds come on slower, rarely cause much of a fever or bad muscle pains. Go get a flu shot next month and you won't get a chance to find out first hand.
When I get fever, body pains, etc…, does the fever cause the body pains or does the flu virus cause the body pains?
No pain due to fever: Fever is part of the body's response to infection, mediated by the release of chemicals (cytokines) from inflammatory cells directed against the agent causing infection. The same is at least partially true for the muscle pain, although there may be some breakdown of muscle cells by the virus (myositis).
Rest, fluids, soup: The "flu" is a bad bug. We recommend getting vaccinated to prevent this illness. To treat for "free" try increasing fluids, resting (important to prevent spread) and chicken noodle soup. Why? Because if mom, wife, partner makes it for you there is someone trying to make you better and this helps recovery. By the way-where are you seeing flu now? Our surveillance isn't showing this anywhere now.
Good question: Because a virus is DNA or RNA, I used to think that a virus could not survive at all outside a cell. In reviewing the literature a while ago, I found to my surprise that some viruses can remain for days or weeks on inanimate objects and in water or sewage for very long periods of time. So it depends on the virus but they can survive outside the body for days to months.
Many types: Every year the flu strain is different.
No: You may develop immunity to one or more types of influenza virus by having been infected or immunized, but this virus undergoes regular changes in its make-up and the new strain present in the community can infect you even if you are immune to other strains. On the other hand, if you are asking about recovery from infection, when you recover you will rid of that strain of flu virus.
It may: Sstudies have shown that influenza virus can persist in a viable form on "fomites" (door handles, keyboards, telephones etc.,), for up to 8 hours. That is why we always tell people to wash your hands. Other ways to avoid influenza are to get your vaccine annually, and use hand sanitize when in public to reduce transmission.
Flu virus: Majority of flu viruses can remain alive on a nonporous surface for one to two days (avian influenaz may live up to 6 days) and 12 or less hours on a porous surface.
