Generally the fragile nature of the virus prevents it from surviving for a substantial amount of time in the open air. The length of time HIV can survive outside the body is dependent on the amount of HIV present in the body fluid and the conditions the fluid is subjected to. Note that HIV is fragile and many common substances such as hot liquid, soap, bleach, alcohol, and the gastric juices found within your stomach can destroy the virus. Your skin is a 100% proof barrier against HIV. The virus cannot enter your skin unless there is an open bleeding wound. If you get blood on your skin, simply wash with water and soap. There is no need to scrub because this might damage the skin. It is good practice to be careful with any blood spill, because one can never tell if the person it came from has HIV or other blood borne infections. You can safely clean such blood spills with water and Clorox. Is there a risk of HIV transmission when having a tattoo, during body piercing or while ... more

The HIV virus is very fragile outside the body, but it can live from several minutes to several hours on the surface of objects in the environment, depending on the situation and environmental factors. more

Generally, when people ask the question, "How long can HIV survive outside the body?" it means they have come into contact with some body fluid that they think might contain HIV, and are worried about transmission. Almost always these questions are about casual contact, and we know the virus is not transmitted except during unprotected sex, sharing needles, or through significant and direct exposure to infected blood. The length of time HIV can survive outside the body depends on: • The amount of HIV present in the body fluid, and • What conditions the fluid is subjected to. In a laboratory, HIV has been kept viable (able to infect) for up to 15 days, and even after the body fluid containing it had dried. However, these experiments involved an extremely high concentration of the virus that was kept at a stable temperature and humidity. These conditions are very unlikely to exist outside of a laboratory. HIV is very fragile, and many common substances, including hot water, soap, ...

Generally the fragile nature of the virus prevents it from surviving for a substantial amount of time in the open air. The only studies on the survival of HIV outside the body have been conducted in the laboratory under controlled scientific conditions. These studies have found HIV is not affected by extreme cold, but it is destroyed by temperatures of 60 degrees centigrade and above. Scientific studies have found that HIV can sometimes survive in dried blood at room temperature for up to six days. It is extremely difficult to assess exactly the length of survival of HIV outside the body in a non-laboratory setting.
