How Does The Hiv Virus Reproduce In The Body
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
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
Lips nose chin: Cold sores (also called fever blisters.) groups of fluid-filled blisters that often erupt around the lips and sometimes under the nose or around the chin. Cold sores are caused by the herpes simplex virus type 1 and are very contagious. The initial infection (primary herpes) may be confused with a cold or flu and can cause painful lesions to erupt throughout the mouth. Once a person is infected wi. ...Read more
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 long: Viruses require living cells in which to propagate in order to remain viable. As soon as they are expelled as free virus they will not last long against environmental conditions. If living cells containing virus are excreted, they too will not survive very long. This is one of the reasons that there is seldom if ever transmission of these agents by inanimate objects. ...Read more
Less than a day?: I don't know of a study on this but in general most viruses don't survive long in dead tissue. Attempts to culture virus post-mortem are usually done as quicly as possible for that reason. I would suspect the success of such a culture more than 24 hours after death would be low. ...Read more

How long does human herpes 8 virus , the one that causes kaposi sarcoma, live outside the body on a door handle?
Herpes: Herpes virus isn't particularly bad to catch. Most people have exposure to herpes type 1 by the time they are 20. About 1 in 5 people show blood evidence of having been exposed to herpes type 2 virus. Most don't even know it. Some people do have trouble with frequent or severe outbreaks. Also it can rarely cause a serious infection of the brain. This is especially true for babies at time of birth. ...Read more
If the body fights an HPV virus to the point where its not in the system anymore. Can the same strand affect the same person twice.?
You are misinformed: HPV is a family of DNA virus strains numbering in the hundreds. They are well known for infecting, self clearing after 2 years or so but with the potential to hibernate in the body forever. It may or may not re-emerge and shed (be contagious). You will develop antibodies to that strain that provide a marker for infection. Re- activation would not be a new infection of that strain. ...Read moreSee 2 more doctor answers
HIV does not hide: There is a quiet phase in most people infected with HIV, but there is no "Hiding". HIV infection is diagnosable by HIV testing after an infection. A negative test results after the appropriate waiting period is a negative result. There is no "HIDING". Dormant phase is a phase we now know where there is ongoing and continuous immune destruction but the body is able to maintain immune function. ...Read moreSee 1 more doctor answer
I don't think so: I'm not aware of any reason to believe that dried blood presents a risk. ...Read more
