AIDS is a very harmful infectious disease, caused by HIV infection. HIV is a virus that can attack the human immune system. It targets the most important T lymphocytes in the human immune system as its main target, extensively damaging them and causing the body to lose its immune function. Therefore, the human body is prone to infection with various diseases and can develop malignant tumors, with a high mortality rate. The incubation period of HIV in the human body is 8 to 9 years on average. Before AIDS, people can live and work without any symptoms for many years.
What is the mode of transmission of AIDS
1. Touch propagation: including touch between similarities and differences There is a greater risk of infection. There are many viruses in semen or vaginal secretions of people infected with AIDS. When moving (), it is very easy to cause slight damage to genital mucosa due to the conflict of intersection sites. At this time, the virus will take advantage of the weakness and enter the blood of uninfected people. It is worth mentioning that since the intestinal wall of the rectum is more prone to damage than the vaginal wall, the risk of anal intercourse is greater than that of vaginal intercourse.
2. Blood transmission: ① Infected blood and blood products contaminated with HIV ② Intravenous drug users infected with HIV, unsterilized needles and syringes ③ Sharing other medical equipment and daily necessities (sharing toothbrushes, razors, etc. with infected individuals) can also infect damaged areas, but it is rare. ④ Syringes and needles are not thoroughly disinfected or not disinfected, especially for children. Dental equipment, delivery equipment, surgical instruments, and needles that pose a greater risk of one injection per person are not disinfected thoroughly. Treatment needles for hairdressing, beauty (eyebrows, ears, etc.), tattoos, and other cutting tools, needles, and bathroom pedicure knives that are not disinfected are not disinfected and are shared with others Blood and blood products of blood donors not seen by HIV antibody of shaver or shared toothbrush, and movement value of bone marrow and organs in similar cases
3. Maternal to child transmission: also known as perinatal transmission, refers to the transmission of HIV by a mother to the fetus or baby before, during, and shortly after delivery, which can be transmitted through the placenta or through the delivery route or breastfeeding during childbirth.
