How Long Does Hiv Live Outside The Body
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 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?
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
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?
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?
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
HIV risk: It does not survive outside of the body. Why do you ask? What is your specific exposure and risk? ...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.
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
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
How long HIV blood survive outside the body on surfaces? Some say instant death HIV won't survive once hits air Others say 1week once blood has dried Some knowledge would really help thank you for help
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?
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
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
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
Varies: It is important to bear in mind that while HIV may live for some time outside the body, HIV transmission has not been reported as a consequence of contact with spillages of blood, semen or other body fluids, although many healthcare workers do come into contact with hiv-infected body fluid. ...Read more
Not long: The virus requires temperature very close to 98.6 and proper moisture. Exposed to an open environment without these conditions, it begins to die immediately, especially in small volumes. It might still be advised to use protection in direct contact with contaminated body fluid spills, but the risk is very low outside the body. Take care ; be well. ...Read more
In general how long would hiv be infectious in a small drop of blood dime sized outside of the body?
Not measurable: Nobody's going to do the hard science required to give a definitive answer to this question, because nobody has gotten sick by contacting a blood drop like this. What we do know is the exposure to casual blood spills -- as in cleaning a cut on an infected child -- simply doesn't infect people. When HIV was untreatable, family members simply didn't catch the virus except through sex or IV drug use. ...Read more
HIV remain infectious outside the body? For how long? Contact with the urine of a soropositive person in a wound it's a risk?
Wrong question: Nobody ever catches HIV by exposure to infected blood or body fluids in the environment. Whether or how long the survives, or other biological reasons, don't matter. No risk and so no worries. (And by the way, urine never transmits HIV.) If you only have safe sex and don't share drug injection equipment, you will never catch HIV. Don't worry about other possibilities. ...Read more
Not very long: People often ask this question because of concerns if they pick up or prick themselves on a dirty needle. HIV does not survive well outside the body. Once the liquid (blood, semen, vaginal fluid, etc.) it is in has dried, the virus is dead and not transmissible. So an old dirty needle, if dry, cannot transmit HIV. Other viruses such as hep b and hep c are much hardier and can survive longer. ...Read more
How long can the HIV virus live outside a human body? If the body fluid it is in is dry, would the virus die?
Within few hours: Cdc has conducted many studies on HIV concentrations outside the body, when these are dried, the virus is reduced by 90to99% over several hours, these concentrations were much higher than they will be outside lab, making theoretical envorenmental transmission outside the body to zero. ...Read more
How long does HIV in urine survive outside the body? Also can it be transmitted by contact with the palms? Theoretical explanation required with sci.
HIV paranoia: Please consider making an appointment today with either an HIV specialist or a mental health counselor. Hiv does not live or survive in urine. Hiv, as you have been taught numerous times, does not infect a person on the palms of their hands. The science of this has been expertly explained to you previously. I wish you well. But it is time for mental health intervention. ...Read more
