How long does a virus last?

Answer 1

few seconds

Answer 2

Each type of virus will respond differently depending on the environmental conditions. In the following, the words "live" or "die" are used; although, these terms are slightly inaccurate since a virus is not a living organism. Viruses do have the need for a host, to keep them able to infect other hosts and so they can reproduce, otherwise they are destroyed or neutralized in the environment eventually, except in rare circumstances as mentioned below.

How long will vary depending on multiple factors of environment, type of virus, and type of host. Some scientists give a generalization of a period around 48 hours outside of a host in the air or on surfaces. Others say, under the right circumstances (the right humidity- usually on the drier side, low sunlight, etc.), a virus can live considerably longer (up to six days). And there are others who speak of some types under some conditions that can live even up to two weeks or more.

Influenza viruses have estimates that range from two hours, to two days, to two weeks. And the Rhinovirus of the common cold is similar.

Still other viruses can survive for long periods of time, in the harshest of environments, even space. They enter a "starvation" state or drying, where they become mostly inactive, however they can still be re-active once inside a host or under the right conditions.

Answer 3

No. Viruses do not have a lifespan because they never die. A virus does notcontain the 6 characteristics of life. A virus can not be killed either. To be cured of a virus, you must be patient or wait or let your T cells or any other helpful things get rid of the virus.

Answer 4

Which virus? The avian flu virus has a 4-5 day lifespan in the air and can travel 2-3km but is higly susceptible to disinfectants containing detergents.But which virus are you talking about?

Answer 5

the doctor said I need to see him if not better than 2 days. My chest still hurts.

Answer 6

Viruses are commonly gone within days or weeks. Whenever a virus enters the body, the immune system starts to attack it an able to completely remove from the body.

Answer 7

A virus does not have a nucleus and is not alive. But a virus can last different lengths of time, depending on the temperature and conditions.

Answer 8

A virus can stay with you for up to two weeks. While fighting a virus it is wise to keep hands clean and get rest to help yourself get better.

Answer 9

That very much depends on the virus. Some live a long time. There are viruses known as slow viruses that have incubation period of months or even years!
