AIDS is an infectious disease caused by HIV infection of the body, causing involvement of organs and organs throughout the body, and the main source of the disease is the HIV virus.
AIDS is a particularly harmful infectious disease that can be transmitted through blood, vertical transmission of mother and child, and even hospital transmission.
HIV can sustain a decrease in the number of immune cells, eventually paralyzing the immune system and making it easy to incorporate various opportunistic infections and tumors in the later stages.
AIDS originated in chimpanzees, how did it spread AIDS to Africa and then to the whole world?
How terrible is AIDS?
HIV is extremely harmful to the human body, once it invades the human body is easy to be fatal, after the HIV virus enters the human body, it will integrate with the cells, and it is difficult to remove from the human body.
After the HIV virus invades the human body, it mainly attacks the immune system, targeting the most important CD4+ T lymphocytes in the immune system, so that the body's immune function is gradually lost.
After the human body has no immune system, it is like an undefended city, all kinds of viruses, bacteria, and microorganisms can invade and cause lesions, so it is still very scary.
When entering the AIDS phase, there will be recurrent oral fungal infections, recurrent herpes simplex virus infection, herpes zoster virus infection, pneumocystis pneumonia.
There will also be repeated bacterial pneumonia, active tuberculosis, deep fungal infections, central nervous system mass lesions, etc., as well as the appearance of Toxoplasmosis encephalopathy, recurrent sepsis, and the late stage is prone to malignant tumors, which can be fatal.
At present, the virus has not been completely cured, and it must be taken for life, and the condition may recur after stopping the drug. Therefore, in general, AIDS is still a very serious disease, we must pay attention to cleanliness and self-improvement, and strengthen personal protection.
Where did HIV come from in the first place?
The origin of AIDS is internationally controversial, but one thing that is internationally recognized is that this disease, which is still incurable today, was first discovered in Africa.
AIDS was first discovered in Africa, and there are many theories about how aids spread to the human world. There is a common belief that HIV first appeared in African green monkeys in tropical rainforest regions of Central Africa. The pathogens of AIDS have emerged and persisted in parts of Africa. This view is currently a relatively common and agreeable view.
How did it enter human society?
We all know that AIDS originated in Africa, and the earliest HIV came from chimpanzees, hive in the chimpanzee body, initially did not infect humans, but because Africa's economy is relatively backward, racial thinking is also relatively backward, on how to transmit to humans, there are the following three statements.
The first: the local indigenous people of Africa were infected with AIDS because of the blood sacrifice of chimpanzees, and later immigrated to the United States, most of the AIDS in the country was infected by injecting blood into hemophilia patients, the first case of AIDS was found on June 5, 1981, at the Centers for Disease Control and Prevention in the United States.
The second: people in Africa have the habit of eating monkey meat, and some experts speculate that it may be that they are infected when they kill monkeys because of contact with the monkey's blood.
Or it may be that being bitten while raising and catching monkeys causes skin damage and bleeding, which can cause the pathogen to enter the inside of the human body. The disease began to spread and spread to other countries, spreading widely throughout the world.
Third: We all know that chimpanzees are very strong, in the primitive tribes of Africa, many men in order to prove their strength, will have relations with chimpanzees, and even blood exchange with chimpanzees, and HIV will enter the human body.
Self-testing methods for AIDS
The main method of self-testing for AIDS is to test by purchasing test strips by yourself, and its accuracy rate is 80 to 90%.
However, there are certain requirements for the time of testing, not immediately after there is a high-risk contact with the test strip test, should be after about 6 weeks, and regular re-examination, until there is a high-risk contact after 6 months, there is no clinical symptoms (fever, lymphadenopathy, diarrhea, rash, etc.), the test result is still negative, can rule out the possibility of infection.
For people with a history of high-risk exposure to AIDS, it is recommended to go to the hospital or prevention and control center to draw blood to test for HIV antigens/antibodies to confirm the diagnosis.
