1.Although HIV virus can survive in vitro, it will not survive more than 3-4 hours in vitro because HIV virus is very fragile.
2.HIV is very sensitive to heat and can be killed above 60℃; however, it is less sensitive to ultraviolet and gamma rays.
3, very sensitive to chemicals: bleach, 2% glutaraldehyde solution, 1:1000 formaldehyde solution, 2% chloramine, etc. can kill HIV virus; alcohol has a good inactivation effect, generally 70% alcohol solution can inactivate HIV virus after 1 minute.
4, even if the broken skin direct contact with HIV is not 100% infected, in addition, the infection is also related to the amount of virus contact (this amount is different for different people, there is no fixed value, the person’s immunity also determines whether the infection).
