AnswerThe best answer I have found for this question is from a CDC pamphlet, from which I extracted the following information:HIV in the Environment
Scientists and medical authorities agree that HIV does not survive well in the environment, making the possibility of environmental transmission remote. HIV is found in varying concentrations or amounts in blood, semen, vaginal fluid, breast milk, saliva, and tears. (See below, Saliva, Tears, and Sweat.) In order to obtain data on the survival of HIV, laboratory studies have required the use of artificially high concentrations of laboratory-grown virus. Although these unnatural concentrations of HIV can be kept alive under precisely controlled and limited laboratory conditions, CDC studies have showned that drying of even these high concentrations of HIV reduces the number of infectious viruses by 90 to 99 percent within several hours. Since the HIV concentrations used in laboratory studies are much higher than those actually found in blood or other specimens, drying of HIV- infected human blood or other body fluids reduces the theoretical risk of environmental transmission to that which has been observed--essentially zero.
Incorrect interpretation of conclusions drawn from laboratory studies have alarmed people unnecessarily. Results from laboratory studies should not be used to determine specific personal risk of infection because 1) the amount of virus studied is not found in human specimens or anyplace else in nature, and 2) no one has been identified with HIV due to contact with an environmental surface; Additionally, since HIV is unable to reproduce outside its living host (unlike many bacteria or fungi, which may do so under suitable conditions), except under laboratory conditions, it does not spread or maintain infectiousness outside its host.
HIV is sensitive to fluctuations in temperature and the presence of oxygen. One place that HIV has been know to survive in is drug injection syringes since these are airtight and often contain blood from the injector.

Yes; depending on the concentration of the virus in the fluid, environmental conditions (temperature, humidity, etc.), it can be as long as several hours.
then blood has dried,iHIV would die!!!
Anywhere from 1-2 weeks.
Hepatitis B
Hepatitis C can live outside the human body for about four days.
Their large surface areas make them dry out easily.
Wet surfaces.
the following are different answers ive found for you :Depends on the virus. For example HIV usually dies fairly quickly outside of the body whereas Hepatitis B can live on a dry surface for weeks.HIV and even Hepatitis C have relatively short lifespans outside of the body. Hepatitis B is about 7 - 10 daysnever read that HBV outside the human body can survive more than 1 month.the lifespan of HIV is not more then 30 second outside human fluids and this is a very short period to play such a mischif.Please make it clear.So this panic can be removed.hope thts at all useful-x-Sebarau
It takes at least 10-25 minutes to be dry on the surface but at least an hour for it to be fully dry
For as long as it takes for the surface to be completely dry.
they dont
Their large surface areas make them dry out easily.
Yes though they can not live long in dry air.
not long there gills will dry out and they will die
Cornstarch has an unlimited shelf live as long as it is kept dry.
