Studies show that AIDS originated in Africa and was brought to the United States by immigrants. On June 5th, 198 1, the US Centers for Disease Control and Prevention published five cases of AIDS in Morbidity and Mortality Weekly, which is the first official record of AIDS in the world.
In 1982, this disease is named "AIDS". Soon after, AIDS quickly spread to all continents. 1985, a foreigner who traveled to China fell ill and died soon after being admitted to Peking Union Medical College Hospital, and was later confirmed to have died of AIDS. This is the first case of AIDS in China.

AIDS prevention:
To prevent AIDS, it is the most basic prevention to control the source of infection, cut off the route of transmission and protect susceptible people from its route of transmission.
Aids is unrealistic in cutting off the source of infection. It cannot be said that AIDS patients are isolated, and its transmission route is not transmitted through daily contact.
Protecting susceptible people is like, for example, we have measles and chickenpox, and we were vaccinated against measles when we were very young, so even if you come into contact with measles patients, the probability of getting measles is very low.
Aids is different. Until now, no effective vaccine has been developed. Because of the particularity of this virus, this point has also been ruled out. So the key point is in the middle. To cut off the route of transmission, we should start with three routes of transmission of AIDS.
For blood transmission, the state should strictly manage the blood source to avoid needle exchange and drug abuse; Mother-to-child transmission, it is necessary to find out that the mother is HIV-positive as soon as possible. If a child is born, it is necessary to go to a regular infectious disease hospital for mother-to-child blocking; Sexual transmission avoids promiscuity.
