　　one healthy From the time a person is infected with HIV to death, it is generally divided into three stages. The first stage is called the acute infection stage of HIV. After infection, a small number of infected people will develop epidemic-like symptoms. cold Symptoms, such as fever, sore throat, rash, swollen lymph nodes, etc., will disappear naturally within 2-3 weeks.

　　Then, the infected person enters the second stage, which is called the asymptomatic stage, which accounts for about 80% of the entire process from infection to death. The patient at this time is called an HIV carrier. On the surface, most infected people are healthy and no different from normal people. It is just that the immune system in their body is engaged in an invisible battle with the virus.

　　HIV destroys large numbers of immune cells every day, and the bone marrow compensates by accelerating the production of new cells, but the rate of replenishment of new cells cannot keep up with the rate of cell loss. In a normal human body, there are about 800 to 1,000 immune cells per cubic millimeter of blood. However, in infected people, the number of immune cells per cubic millimeter of blood gradually decreases at a rate of 50-70 per year. When the number of immune cells decreases to only about 200 per cubic millimeter of blood, the rate of decline will accelerate. The duration of the asymptomatic period of an infected person can be long or short, ranging from 2 years to 20 years. The duration is closely related to the route of infection. Generally, the duration of the asymptomatic period for people with menstrual blood infection (mainly illegal blood collection and sharing of syringes) is 4-5 years, and the duration of sexual intercourse infection is generally 11-13 years. If the asymptomatic period of an infected person can reach 13 years, it can be called a long-term survivor.

　　When the immune cells in the infected person's body can no longer compete with HIV, it marks the final stage of HIV infection, which is called the symptomatic stage. At this time, the infected person is called an AIDS patient, and they are very susceptible to other diseases. disease Infections, some common infectious diseases that usually do not pose a threat to human life, such as pneumonia, will become uncontrollable once they enter the body of AIDS, and people generally die within 6 to 24 months.
