How does AIDS spread? The Pathogen transmission of AIDS include sexual contact, blood transmission and mother to child transmission.
The full name of AIDS medicine is acquired immunodeficiency syndrome. It is an infectious disease caused by AIDS virus, or human immunodeficiency virus. After HIV enters the human body, it will destroy the immune function of the human body, resulting in Opportunistic infection and tumors that are difficult to cure, and finally the patient will die. This disease often presents different clinical symptoms and signs in different individuals. The immune deficiency caused by HIV is different from that caused by other diseases and drug side effects, and is transmitted from person to person through different methods, hence it is called acquired immune deficiency syndrome.
HIV is a type of infectious disease that can be easily traced back to life. What are you doing?

HIV directly attacks the human immune system, destroying the cellular and Humoral immunity of the human body. It mainly exists in the body fluids (blood, semen, Vaginal discharge, milk, etc.) and multiple organs of infected persons and patients, and can be transmitted through the exchange of body fluids containing HIV and organ transplantation. HIV has weak resistance to the external environment, and high temperatures, dryness, and commonly used disinfectants can kill HIV.
Individuals who have HIV in their bodies but do not show any clinical symptoms or signs of AIDS are referred to as HIV infected individuals. The human immune system is severely damaged by HIV, and when the body experiences various opportunistic infections and tumors, it becomes an AIDS patient. After the human body is infected with HIV, some infected individuals can survive for a long time, so some scholars have proposed the concept of long-term survivors. The basic conditions are: survival after 12 years of HIV infection; The immune function of the body is still good, and CD4 cells are maintained at a certain level; No obvious clinical symptoms of AIDS.
After the human body is infected with HIV, it usually takes 2 to 12 weeks, with an average of about 45 days before HIV antibodies can be detected in the blood. Because the period from infection with HIV to the production of antibodies by the body during which HIV antibodies cannot be detected is called the window period. During the window period, HIV antibodies cannot be tested, but due to the presence of HIV in the body, there is also contagiousness during the window period. It takes 0.5-20 years for the human body to develop into an AIDS patient after being infected with HIV, with an average of 7-10 years, which is called the incubation period. Latent HIV infected people's blood, semen, Vaginal discharge, milk, organs contain HIV, which is infectious..
