How long can HIV survive on a towel?

The viability of HIV in vitro is very poor. Once the body fluids and blood that take away HIV leave the human body, they will be quickly inactivated due to changes in blood volume, dryness, temperature, pH and humidity.

Trace blood, within ten seconds at the earliest. The average threshold is within 6 seconds. It is no problem to say that it is instantaneous inactivation. Conservatively speaking, within five minutes, five minutes at most, and less than five minutes in normal environment, the viral load will drop below the infection threshold.

Even in the laboratory environment, HIV is difficult to survive, and its activity drops by 90% to 99% after drying for 2-3 hours.
