How does AIDS spread? AIDS is transmitted through sexual contact transmission, blood transmission and mother to child transmission.
The full name of AIDS medicine is Acquired Immunodeficiency Syndrome (AIDS). It is caused by HIV, which is an infectious disease caused by human immunodeficiency virus (HIV) infection. After HIV enters the human body, it disrupts the body's immune function, leading to a series of opportunistic infections and tumors that are difficult to cure, ultimately leading to patient death. This disease occurs in different individuals and often exhibits different clinical symptoms and signs. HIV immunodeficiency is different from immunodeficiency caused by other diseases or drug side effects. It is called acquired immune deficiency syndrome because it spreads between people in different ways.
HIV is a retrovirus with strong rapid mutation ability, which not only makes it difficult for the human immune system to resist its invasion, but also brings difficulties to the development of drug specific treatment and vaccine prevention. HIV directly invades the human immune system, destroying human cellular immunity and humoral immunity. It mainly exists in the body fluids of infected individuals and patients (such as blood, semen, vaginal secretions, milk, etc.), as well as in various organs. It can contain HIV body fluid exchange or organ transplantation. HIV has weak resistance to the external environment and can kill high temperatures, dryness, and commonly used disinfectants such as HIV.
A person who has HIV in their body but does not show any clinical symptoms or signs of AIDS is called an HIV infected person. When the human system is affected. HIV is severely damaged, causing various opportunistic infections and tumors in the body, leading to the development of AIDS patients. 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 survival. The basic conditions are as follows: surviving for 12 years after HIV infection; Good immune function, CD4 cells maintained at a certain level; No obvious; Clinical symptoms of AIDS.
It usually takes 2 to 12 weeks for the human body to be infected with HIV to be detected in the blood, and on average, it takes about 45 days for HIV antibodies. Because HIV cannot be detected during the period when the body produces antibodies during infection, antibodies are referred to as the window period. Although HIV cannot be measured during the window period, there is already an antibody against HIV in the body, so the window period is also infectious. After human infection with HIV, it takes 0.5-20 years, with an average of 7-10 years, to develop into AIDS patients, which is called the incubation period. During the incubation period, the blood, semen, vaginal secretions, milk, and organs of HIV infected individuals contain HIV and are infectious.
