Inactivation of HIV in vitro for 3 seconds
Due to the drier and hotter external environment, HIV becomes inactive in just three seconds outside the body, and HIV quickly loses its vitality. In a humid environment, survival may take a few minutes.
Because HIV itself is very fragile, its survival ability is very poor after leaving the human body. It is difficult to survive after leaving the human body because of its high temperature resistance and low tolerance. When the virus lacks appropriate temperature, pH, and body fluid concentration, it is easy to lose its activity through blood, sexual transmission, and mother to child transmission.
How much HIV infection does it take to reach
AIDS infection must meet two conditions at the same time. First, the AIDS virus needs sufficient vitality. Second, these energetic AIDS viruses have just entered fresh blood or fresh wounds. There is currently no research on how many viruses are needed.
The most important mode of transmission of AIDS is through sexual transmission, blood transmission and mother to child transmission. General life contact, dining together, shaking hands, hugging, etc. are basically not infected. Once AIDS infection is obvious, it needs to be treated as soon as possible.
The occurrence of AIDS is closely related to bad habits in daily life. AIDS is mainly transmitted through blood, sexual transmission, mother to child transmission, and high-risk sexual transmission such as condom free or condom free anal sex. AIDS first appeared in the United States, but it is not clear how HIV is produced.
AIDS is no stranger to everyone. We all know that AIDS is an infectious disease. It is usually caused by unclean sexual activity or blood transmission. For those who are ill, AIDS is incurable and highly contagious. AIDS is a particularly terrible disease. How did you get AIDS? HIV is transmitted to people through blood contact and then to the world. AIDS was first discovered in the United States in 1981. AIDS, also known as acquired immunodeficiency syndrome, is a chronic infectious disease caused by HIV infection. The HIV virus invades the human immune system, causing a decrease or even loss of immune function, leading to various opportunistic infections and tumors.
AIDS originated in Africa and was brought to the United States by immigrants. Human HIV may come from wild chimpanzees in Africa. But so far, scientists have not found how AIDS is transmitted from chimpanzees to humans. Most scientists believe that humans are likely to be infected by chimpanzees, or they may have accidentally contracted the virus during slaughter. HIV is a pathogenic microorganism that can infect people with AIDS. After HIV infection, HIV will mainly attack human T and B lymphocytes. Causing loss of immunity, severe damage to multiple organs of the human body, and even endangering life. AIDS is a difficult and complex disease, which cannot be completely cured in clinical practice.
At present, it is not sure how HIV is produced, but it will damage the immune function of the human body. AIDS is mainly transmitted through mother to child transmission, sexual transmission and blood transmission. Of course, if there is no AIDS, AIDS will not spread, but if one person has AIDS, it may spread to others. After the window period ends, it is necessary to check for AIDS antibodies to determine if there is an infection. Once AIDS infection is difficult to cure, there is no very effective way to cure AIDS. Therefore, AIDS prevention should be strengthened. Firstly, control communication, establish a concept of security, and promote safe behavior. Secondly, controlling blood transmission, improving and ensuring the safety of blood and electrical appliances, and avoiding the use of intravenous drugs. Preventing mother to child transmission of HIV, terminating pregnancy and promoting artificial feeding can significantly reduce vertical transmission and prevent accidental transmission of HIV.
