How Long Does Hiv Virus Live Outside A Human Being
Not long: Viruses are critters which live inside cells and must have nutrients of a cell to remain alive. Most will die rapidly after leaving the body unless retained in body fluids within cells in those fluids. This takes varying times to resolve. As a general rule HIV is not transmittable casually. It needs direct tissue contact. Blood, shared needles, sex, organ transplant. ...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
NoroV Contagion: Whereas the symptoms usually begin 12 to 48 hours after ingesting the virus, there is no evidence that sick persons can become long-term carriers of the virus, but the virus can be in the stool and vomit of infected persons, from the day they start to feel ill to as long as 2 weeks after they feel better." http://www.Health.State.Mn.Us/divs/idepc/diseases/norovirus/basics.Html#duration. ...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
It doesn't: HIV does not survive outside of the body. It is not ever caught by touching it or any other thing it is in or on. Millions of humans have now survived HIV free after taking care of infected humans. They have been bled upon, shat upon, vomited on, spit upon, peed upon. HIV is not caught by touching it or anything it has been in contact with. ...Read more
Is it possible to catch HIV without semen but from precum? Can HIV antibodies live outside its host? If so, how long?
For how long the scratch is capable of transmitting hiv I mean how long it takes to not contract hiv from infected blood?
Depends on moisture: HIV is a fragile virus. It needs moisture and warmth to survive. If the scratch from an HIV + person is new and has flowing blood then it is infectious. Question is, how long before it is not infection? My view of this is that if the blood is in any way moist, then its infectious. If it is completely dry and been that way for a while, unlikely to be infectious. ...Read more
It depends: Hsv virus is easily inactivated by exposure to ph <4, temperatures >56°c for 30 min, pasteurization (60°c for 10 h), and microwave heating for 4 minutes. Survival outside host: hsv virus survives for short periods of time outside the host. It can survive on dry inanimate surfaces (survival ranges from few hours to 8 weeks). They survive longer at lower humidity. ...Read more
Depends: It depends on what you mean by dormant. Blood tests are generally positive within a few weeks of infection, and many people develop temporary symptoms during acute infection. However, after recovery from acute infection, you may have no symptoms for many years. On average, it takes 10 years to progress to aids without treatment. ...Read moreSee 1 more doctor answer
How long does human herpes 8 virus , the one that causes kaposi sarcoma, live outside the body on a door handle?
How long does the herpes virus 1 and 2 survive outside the human body, like on surfaces? Can you catch herpes this way?
Up to 3 - 4 hours: It's possible, but not super likely. You have to have a pretty large quantity of virus hanging out on the inanimate object (say for instance a straw), and it has to come into direct contact with your mucous membrane (say for instance your lips), for transmission to occur. Here's some info on herpes: http://health.Nytimes.Com/health/guides/disease/herpes-simplex/print.Html. ...Read more
