How Does Hiv Affect 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
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
HIV infection : HIV is a tricky infection because indeed, a patient may have it and not be aware until the immune system is totally wiped out and AIDS sets in. This is partly why HIV is so devastating - it's working behind the scenes to destroy the pt's immune system. On average that takes 8 years before the pt will present with AIDS symptoms. Thus the value in getting checked if any doubts are there. Be safe! ...Read more
HIV infection: The acute infection stage of HIV usually begins to be widespread at about fourteen days after exposure. Most people do not experience any symptoms during this phase. But, those that do report a severe flu-like illness. Untreated, in a man, the average length of infection to death is eleven years.But, we do not need to worry about that. With treatment today, the length of life is 53 plus years. ...Read moreSee 1 more doctor answer
What is the ph level like outside of the human body? Does HIV usually died within seconds of leaving the body in trace amounts?
PH is irrelevant: It would help to know why you are concerned. HIV is never, ever caught by exposure to the virus in the environment. Asking if the virus survives in the environment -- regardless of pH, temperature, or anything else -- therefore is irrelevant, if your concern is possible exposure and infection. But to answer the question directly, HIV dies rapidly when blood or contaminated fluids dry out. ...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
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
If hiv/aids blood goes to another human body then how many days will it take to for symptoms to show?
Not for a while: There is a 3 months window before the body converts after exposure. And symptoms may not show for some time afterwards, sometimes years. ...Read more
Hi, how long can an HIV virus last outside human body (like on needle or something) that it can be considered a risk?
HIV virus: Hiv is extremely sensitive to fluctuations in temperature.Outside of the human body, the virus dies within minutes. The one place that HIV has been shown to survive for extended periods of time (several days) is in needles used with syringes; the needles frequently contain enough blood to prevent the HIV from drying out. ...Read more
