A member asked:

After how long are the flu viruses detectable in our body?

A doctor has provided 1 answer

Depends on Antibody: Usually it is the antibody response that we are measuring when we are trying to determine if a virus is still present. Some types of antibodies tell us if a certain virus was ever present. Then there are some types of antibodies that tell us if the infection are still active or not. But to answer your question flu viruses only last about a couple of days (6-7) in your body if you are healthy.
