how many seconds HIV virus can be alive out of body?

Answer 1

The exact duration depends on the type of body fluid, environmental conditions etc, but generally the HIV virus is very fragile and does not last long outside the human body.

According to the CDC;

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 page 3, Saliva, Tears, and Sweat.) 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 for days or even weeks under precisely controlled and limited laboratory conditions, CDC studies have shown that drying of even these high concentrations of HIV reduces the amount of infectious virus by 90 to 99 percent within several hours.

Answer 2

HIV, despite being 'smart', is also a VERY fragile virus. It cannot eist for more than a few seconds outside of the environ it requires: moist, human body temperature.
Hepatitis C, conversely, can live happily in a spot of cold, dried up blood on a dirty floor for many months making it infinitely more infectious than HIV.
All I know is that it is a few seconds once the temperature has fallen below 37C.

Answer 3

virus is a plazma stage between living and non living it becomes active when gets conducible environment other wise keep silent. therefore HIV virus is dead as soon as it leaves body fluid AND NOT BODY ONLY.

Answer 4

5 Minutes approximatly...but there are conditions that can lessen or increase survial time by a little bit.
