When it comes to infectious diseases, I believe that many people will pop up "AIDS" in their minds, which is an incurable infectious disease, mainly through vertical transmission of mother and child, blood transmission and other ways.
AIDS is a very harmful infectious disease, a virus that can attack the human immune system, and HIV infection can cause the organs of the whole body to be affected.
In real life, people are very afraid of AIDS, and they are even more avoidant of AIDS patients, not only that, most people look at this kind of disease with colored glasses, thinking that it is a disease that is not clean and proud.
I believe that many people are very curious, how did AIDS come about? Today, I will take you to understand the reasons for this, which may touch everyone's knowledge blind spot.
01
The origin of AIDS
According to statistics, by the end of 2020, there were 38 million people living with HIV in the world, of which the highest infection rates were in sub-Saharan Africa and the Caribbean, accounting for about 3/4 of the total number of infected people.
After decades of research by many scientists, it has been found that the HIV virus originated in a chimpanzee in Africa, and the HIV virus can infect cattle, sheep, horses, cats, canines, primates, etc.
In terms of virus taxonomy, HIV virus is a member of the lentiviral class, which is a virus that can cause symptoms of chronic persistent infection in various mammalian organisms.
02
AIDS originates in chimpanzees?
On June 5, 1981, when AIDS was first documented in the world, the U.S. Centers for Disease Control and Prevention published a case report in the weekly morbidity and mortality magazine, which was also officially named "AIDS" and spread around the world.
Studies have found that the SIV (monkey immunodeficiency virus) carried by the chimpanzee subspecies in west-central Africa is highly similar to THE HIV virus. It was later confirmed that HIV is a virus in the blood of chimpanzees that crosses the interracial barrier and enters the human body.
03
How did chimpanzees spread AIDS to Africa and then to the world?
As we all know, Africa is a relatively backward country, the daily life of local residents is very difficult, and even some residents cannot solve the problem of food and clothing, so they are even more unable to guarantee health.
African locals will kill animals to solve the problem of food and clothing, in order to fill the stomach, chimpanzees have also become the prey of African greeting tribes, local residents eat HIV-infected chimpanzee meat after the virus directly invades the human body.
Secondly, when a hunter kills prey, the wild animal carries the virus in its blood, which may also contaminate the hunter's wound, so as to enter the human body to increase the chance of infection.
In the primitive tribes of Africa, there are even many males who have sex with chimpanzees, resulting in blood exchanges and the introduction of HIV into the human body.
04
What are the manifestations of HIV infection?
1. Lymphadenopathy
Lymphadenopathy is one of the main clinical manifestations of pre-AIDS, which generally occurs in the head and neck, groin, behind the ears, anterior ears, armpits, submandibular lymph nodes and other parts.
Once the lymphadenopathy caused by AIDS occurs, it is ineffective for general treatment and will continue to swell for more than half a year.
2. Rash appears
Rash phenomenon in life is very common, many times due to skin allergies appear similar symptoms, most people will not cause attention, in fact, rash is also divided into many types, by HIV infection caused by the rash needs to be examined in time.
Most AIDS patients develop a rash on the skin and develop in various parts of the body as the condition progresses.
3. Headache and fever
Aids patients may have headaches and fevers in the early stages, mainly due to infection caused by low immunity caused by HIV.
05
How to effectively prevent AIDS
★ Sick medical treatment requires examination and treatment in regular hospitals, avoiding the use of unsterilized medical devices, especially when transfusing blood, and rejecting blood from irregular units of unknown origin.
★ Personal items such as toothbrushes, razors, and facial shavers are not borrowed or shared.
★ Clean self-love, many AIDS patients have had one-night stands and extramarital affairs, because the sexual partner has no physical disease you have no way of knowing, once you do not take protective measures, it is easy to get AIDS.
