Hcv Infected Blood Survival Outside The Body
I don't think so: I'm not aware of any reason to believe that dried blood presents a risk. ...Read more
How long can HIV virus survive outside human body in dried blood & liquid blood under normal circumstances ?
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 moreSee 1 more doctor answer
Various ways: The virus has reservoir cells where it remains inactive in tissues. These are macrophages and in the nervous system some neurons. It lives within lymphocytes (cd4 cells), and other cells which possess a receptor site to which it can attach and enter the cells. These cells then carry it into tissues. When the virus first enters the body it does so onto receptive surfaces. ...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 moreSee 1 more doctor answer
HIV is a Virus: I would be very curious to know the context of your question. Hiv in any normal human setting will be potentially contagious regardless of the 'temperature' of the person infected with hiv. Are you asking because you think there is a situation where HIV would not infect someone? Heat treatment of an infected human would in no way work. It would not rid the body of the HIV genes in the human. ...Read moreSee 1 more doctor answer
Can very small blood on HIV infected persons lips infect another person through sharing same food/fork? What is the likelihood?What is fresh blood/cut
No risk: Nope. There is no risk here. Even in the improbable scenario of imperfect skin. ...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
Does hiv window period depend upon the number of virus entered in body?
More virus=early hiv detection by pcr or 4th & less virus=late hiv detection?
Although haart therapy only kills free floating HIV virus, won't the dormant reservoirs eventually die off leaving the person free of hiv?
Dormant HIV: Unfortunately, some of the cells the virus infects can lie 'dormant' for >13 years. Our hope was that treating the virus would rid our patients of the infection in time but we need to make those latent cells infected w/virus 'apoptose' or die ; prevent new immature cells from being infected. It has been more difficult than we anticipated but work is actively being done. We have hope! ...Read more
If the fresh blood of hiv+ person drops on open wound of a normal person, then HIV can transmit, how much % chances are there?
Unfortunately, yes: Both hepatitis b and c can survive for days, and perhaps even over a week, outside the body. This is why ever sharing any paraphernalia, including cookers, for drug use could lead to infection. Getting "stuck" with a needle, or reusing needles for injections like testosterone or vitamins, can also lead to hepatitis b or c injection. Always be careful at tattoo parlors, piercing places, etc. ...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
