How long does HIV live outside the body? I heard a couple seconds.

How long does HIV live outside the body? I heard a couple seconds.

It varies.: In certain conditions, the virus can survive outside the body for several weeks (such as inside a syringe). Survival depends on which body fluid it is in, volume of the body fluid, concentration of the virus within it, temperature, acidity, and exposure to sunlight and humidity. Hiv transmission has not been reported as a consequence of contact with spillages of blood, semen or other body fluids. ...Read more

Hiv (Definition)

Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more

How long does HIV live outside the body? does the fluid need to be dry or can it die before it dries?

HIV is hard to catch: HIV is never contracted by touching it through the skin. It is not caught from inanimate objects. It is not caught from "outside of the body". ...Read more

How long does hiv live outside the body? Wet and dry blood. Thanks

Doesn't matter: The concern in questions like this, whether or not stated directly, is that HIV transmission might occur from contaminated environments or objects. But there are no such infections. The busiest HIV/AIDS clinics never have patients without traditional risk factors. That said, HIV is dead once blood dries, and probably survives idefinitiely if it remains wet. But it doesn't matter. ...Read more

How long does HIV live outside the body? Does heat kill it faster?

How long does HIV live outside the body? Does heat kill it faster?

HIV dies right away: HIV cannot live outside of the body -which is a very good thing. So if you're worried about an 'exposure' at least this is in your favor. It's always good to practice safe sex though-esp. in this modern age. I see many young people not paying attention to their own safety-and sadly a number of new cases are occurring. Most of these are in gay young men in their 20s. Be safe. Check with a doc if Qs ...Read more

If HIV positive blood was on a surface, could someone get infected if they touched it with an open wound? How long does HIV live for outside the body?

If HIV positive blood was on a surface, could someone get infected if they touched it with an open wound? How long does HIV live for outside the body?

Yes: But this would be extremely rare. Hiv will not survive long outside the body, but might if the blood has not yet dried up entirely. Why in heavens name would anybody touch somebody's blood on a surface with their own open wound? A very improbable scenario. But the answer to your question is that this is possible. ...Read more

How long HIV does live outside the body? If it is a tiny or little more amount of fluid? How long it takes the virus to die in a fluid wet or dry?

Why: It doesn't survive. But that doesn't matter. Hiv is not caught by touching it or the fluid it may be living in. That is very well understood. What is your specific concern? ...Read more

How long does hiv survive outside of the body ?

How long does hiv survive outside of the body ?

Depends on details: Realize that "outside the body" can mean: on the surface of my arm, on my steering wheel, in a freezer at the lab, on a bagel, etc... So, there is no answer unless the question defines Where, What acidity (pH), What temperature, What humidity, What lighting (sunlight, amount of UV), etc.. From a daily life standpoint, there is no worry about catching HIV on any surfaces that we routinely touch. ...Read more

Why isn't there an average time on how long HIV survives outside the body? Is it preference, or is there a chance it can be caught environmentally.

Why isn't there an average time on how long HIV survives outside the body? Is it preference, or is there a chance it can be caught environmentally.

Reality: Let's think. Who's going to do a worthless study like this? We know people aren't getting HIV from fomites. Studies of families with hiv-positive leukemic kids showed it was never transmitted despite family members actually contacting blood. To test infectiousness, you're going to have to inoculate animals with shed blood -- and what's the purpose? All we know is that the bugs die very fast. ...Read more

Roughly how long does HIV survive outside of the human body?

HIV: This is complicated. The virus is capable of surviving several hours outside the body, but only inside of living cells. Drying of secretions containing the virus reduces the counts by 99+% quickly. You do not get this virus transmitted in this fashion unless you are sharing needles with somebody or are inadvertently stuck with a needle containing fresh blood. ...Read more

How long can hiv and hepc live outside of a body is it easy to catch hiv or hepc once outside of body?

It doesn't happen: Blood borne viruses (HIV, hepaitis B and C viruses, or others) are not acquired from contaminated environments. Virus survival is brief, especially when blood or body fluids dry, but what really matters is that nobody is known to have been infected in this way. Use common sense hygiene (wash hands etc) if you come into contact with wet body fluids, blood, etc. Otherwise don't worry about it. ...Read more

How long does HIV survive outside the body? Like a teaspoon of blood for example.  I know its a short time but minutes? hours, days?

Very short time: Why do you ask? "A teaspoon of blood?" Where did you run into such a thing? Only you know what really happened, and especially, I'm concerned that you're doing needle drugs. This alone is a reason to get with your physician for help -- tell the truth and you may well save you life. If you have any reason to think you have contacted HIV, please get one of the new early-detection tests. Be brave. ...Read more

Hi, I was wondering how long does HIV start to take an effect on a body? can it start in 3 or 4days? Also what's the chance of HIV from protected sex?

Hi, I was wondering how long does HIV start to take an effect on a body? can it start in 3 or 4days? Also what's the chance of HIV from protected sex?

No risk, no worries: There is almost no chance of catching HIV from condom-protected sex, if the condom didn't break. And HIV cannot cause any "effect on the body" for at least 10-14 days. Any symptoms you have at 3-4 days are unrelated to HIV. ...Read more

How long is HIV active in sperm outside the body?

How long is HIV active in sperm outside the body?

Not Long: HIV is not very hardy out of the body but it is found in semen. Presumably it could survive up to a few hours at most but would generally be deactivated as the semen dried out which happens fairly quickly. It takes a very large inoculum (total volume of infectious agent) for infection to occur which is why the odds of infection from 1 sexual encounter with a known HIV + individual is ~ 1 in 1000. ...Read more

How long could HIV semen still be infectious outside the body?

Don't take chances: While HIV is reported as only capable of living hours-days in the environment, some hepatitis viruses and other infectious agents can live much longer--also, you do not want to be the first-case-ever for something. Clean up with commercially available antiviral/antimicrobial cleaner or wipe. ...Read more

How long outside the body can a drop of blood with HIV remain contagious?

Very quickly: Hiv can not live out side the human body host for a long time. If the blood is dry its most likely not contagious. If its still wet or less than 10 min, it may still be contagious. Always protect your self with condoms and rubber gloves. Bleach can kill the virus and other bacteria on contact. ...Read more
