If you get an illness (flu,cold,throw ups) and are exposed to it again, are you immune to catching it twice?

Question

And if you're not 100% immune, how much immunity does your body normally provide against a second attack? I guess I'm basically asking about viruses and flu. Thanks in advance for your help!

Answer 1

You mentioned viruses and if your sickness was viral, you usually have the anti-bodies to cope with another exposure without getting sick. However, there are thousands of strains of viruses...how do you know which one you were exposed to or experienced? You don't. Even with a flu vaccine you can still get the flu, just a different strain. The CCC puts out one vaccine a year; the one that they "guess" will be the most prolific, and that is what everyone gets. Next year, it will be changed. Also, those symptoms could be caused by a bacterial infection. Your best bet is to see a doctor and get blood work. Even then, most flu viruses are self-limiting and will go away when they all stop multiplying, usually 10 days or so, no matter what you do. I would suggest good handwashing techniques (even so far as keeping hand gel handy after using a public shopping cart or ink pen) and keeping away from people who are obviously sick. Godloveya for asking a question that will benefit others!!!

Answer 2

The complete answer is complex, but here's the simple version. With "most" viruses, cold and flu especially, you are immune once your immune system has actively fought it. There are thousands of cold viruses, and this is why you can catch colds your entire life, because presumably you are not catching the same cold twice. Likewise, the flu virus is different each year. This is why new vaccines must be formulated for each new flu season. The reason I say "most" viruses above is because there is some evidence that viruses like chicken pox can be repeat offenders. It doesn't happen often, but it has happened. I hope this helps answer your question.

Answer 3

You can catch the "same" cold or flu repeatedly. All cold and flu viruses/bacteria are all not the same, even though symptoms may appear the same. Say you have the flu....then your best friend gets it....you can get it again! When it travels from one person to another the cold/flu mutates.
And no, you can not get immune to the cold or flu. Even flu vaccines don't guarantee anything. Alot of people still get the flu. Others don't.
Hope that helps. Good Luck

Answer 4

When you overcome an illness, your body makes antibodies in response to the antigen. These may give you a boosted resistance to the illness and catching it again, but you are not immune.
You'll still need to live as cleanly as you can, avoiding as much exposure as possible to the illness. If you just got over the illness, you will have resistance. It won't be necessary to move out of your house if people in your family still have it, but you should be clean and avoid direct contact.

Answer 5

You can build up antibodies to each strain of flu .. variations you can sometimes get milder cases from. Most flu's do not cause you to throw up if you did that might have been food poisoning.
Colds can come anytime there is not cure for colds, but you can take vitamins to have less severe ones.

Answer 6

Yes you are immune from that exact virus but they have a sneaky way of changing enough that you can't fight the next one.

Answer 7

If you are speaking approximately the typical bloodless, then the reply is NO, you can't capture the identical bloodless two times. There are approximately one million traces of the typical bloodless and your frame develops antibodies for each and every bloodless virus that you just get.

Answer 8

YOU CAN CATCH A COLD MORE THEN ONCE, FLU NOT LIKELY.

Answer 9

no, you can get the same viruses over and over
