The English abbreviation for AIDS

The acronym for AIDS is HIV.

1. Cause.

AIDS is caused by human immunodeficiency virus infection. After the isolation of lymphadenopathy-associated viruses from the Pasteur Institute in France, in 1984, the Oncology Institute of the United States isolated human T-lymphotropic virus type III, and HTLV to III then confirmed LAV and HTLV to III as HIV.

HIV is an RNA virus with a diameter of 100 to 140 nm, consisting of two envelope proteins, gp41 and gp41, and has structural genes and regulatory genes, gag (core protein), pol (reverse transcriptase), and env are associated with replication. HIV to II and HIV to I types were found to be 80% serocrossing and 20% negative in 1986.

2. Sources of infection and routes of transmission.

Source of infection: patients, HIV carriers, asymptomatic seropositive people are the most infectious.

References:

There are three ways of its transmission : Sexual transmission: homosexual, heterosexual, bisexual. Blood and blood products: direct importation, organ transplantation, artificial insemination, **** with needles, **** with instruments. Mother-to-child transmission: intrauterine, labor and delivery, breastfeeding.

HIV:

HIV is a lentivirus that infects the cells of the human immune system and is a type of retrovirus.

HIV was first discovered in 1981 in the U.S. In 2015, all sources of HIV strains were fully identified for the first time in humans. HIV integrates into the genome of host cells after infection, and antiviral treatment does not eradicate the virus.

During some periods of the course of HIV infection, especially early and late, infectious viral particles are present in certain body fluids containing immune cells, plasma, lymph fluid, or tissue fluid.

HIV has a very poor ability to survive outside the body, does not tolerate high temperatures, has a low resistance, and is not easy to survive away from the body. It is only possible to be infected through direct contact with certain body fluids (blood, semen and pre-seminal fluids, rectal fluids, vaginal secretions, breast milk, etc.) within the body of an HIV-infected person.

AIDS was first recognized in the United States in the early 1980s and was ignored by the conservative Reagan administration at the time.

But with the continued work of the Centers for Disease Control and Prevention (CDC) and knowledgeable doctors and scientists, convincing epidemiologic data were accumulated that showed AIDS had a contagious cause, and with an increasing number of infections due to drug addicts*** and blood transfusions, many scientists began to investigate the contagious pathogen.
