Do viruses survive outside the body?

Question

Specifically the virus that causes verrucas and warts.

Answer 1

Generally viruses can survive outside the human body from a few seconds up to 48 hours.Flu viruses tend to live longer on surfaces than cold viruses. Also, cold and flu viruses survive for longer periods on nonporous surfaces — such as plastic, metal or wood — than they do on porous surfaces — such as fabric or paper.
Another example, the SARS virus can survive for hours on common surfaces outside the human body.

Answer 2

Viruses do survive outside of the body - but the length of time that they live depends on the conditions and also the type of virus. Viruses need to be inside a host cell so that they can replicate (not feed) they can not be cultivated without a host cell - which is why you somethimes give a sample in at the doctors and it comes back as no infection. This is because they failed to cultivate any bacteria in the lab - so it must be a viral infection.
Viruses are thought in some instances to last for decades - so, for example, digging up a mass grave from the last century's flu pandemic would be very dangerous without proper protective procedures.

Bear in mind that viruses still have to get inside the body in some way before they can infect you.

Answer 3

There are two types of herpes simplex virus: HSV-1 and HSV-2. Both virus types can cause sores around the mouth (herpes labialis) and on the genitals (genital herpes). Cold sores are caused by the herpes simplex virus (HSV).
Cold sores sometimes called fever blisters, are groups of small blisters on the lip and around the mouth. The skin around the blisters is often red, swollen, and sore. The blisters may break open, leak a clear fluid, and then scab over after a few days. They usually heal in several days to 2 weeks.
The herpes simplex virus usually enters the body through a break in the skin around or inside the mouth. It is usually spread when a person touches a cold sore or touches infected fluid—such as from sharing eating utensils or razors, kissing an infected person, or touching that person's saliva. A parent who has a cold sore often spreads the infection to his or her child in this way. Cold sores can also be spread to other areas of the body.

Answer 4

There are a number of factors that effects whether a 'virus' can survive out of the body. Simply it is not a yes or no answer. It depends on whether the virus is air born, food born etc. Best way of checking is to research a specific virus.

Answer 5

All viruses can survive outside of the body. Some viruses, like HIV are very fragile and cannot survive more than a few minutes. On the other hand, the viruses that can cause Hepatitis are very tough and can withstand quite high temperatures before they are destroyed.

Answer 6

yes..some do..some also lie dormant in the body.. a variant of the herpes virus causes warts and verrucas and can come from your own body and immune problems

Answer 7

Yes, I believe so. That is what caused the pendemic such as SARS or Bird Flu (although bird flue hasn't reached the human-to-human transition yet). When you go near someone with flu, you would eventually get the disease too.

Answer 8

It depends on the kind of virus, the majority can not live outside because of the temperature.

Answer 9

yes, but not long. they need to feed. so they need a human body to feed from. if they dont, they die in about 1 hour/1/2 an hour

Answer 10

Yeah there are waterborne and airborne viruses. Viruses are everywhere, they are not all bad. And they inhabit every part of our world.
