Abstract:
OBJECTIVE To define the regularity of survival ability of HIV in natural environment,and prevent(infection) through contacting with positive body fluids during daily life or medical work.METHODS Having been diluted by sterile water or 10% serum RPMI 1640 medium,HIV was exposed to 4℃,room temperature(20-26℃) or 37℃ for different period of time.TCID_(50) of these samples was detected.Non-pathological samples were blind passaged for three generations.RESULTS HIV infective ability persisted more than 35 days both in(water) and medium at 4℃;whereas it persisted 7-14 days in water,14-21 days in medium at room temperature and 37℃.CONCLUSIONS HIV has higher resistance in natural environment.To prevent accidental spreading of HIV,HIV positive liquids and contaminants staffs should be treated carefully.
