AIDS is a kind of infectious disease that seriously endangers the health of all mankind. If it is not well controlled, it will spread widely among the population, causing unimaginable consequences.
Many people have heard of AIDS, but not everyone understands that there are two types of AIDS.
What type of AIDS is causing so much damage to us?
Here is an introduction.
When it comes to the type of AIDS, it is necessary to mention the human immunodeficiency virus (HIV), the culprit that causes people to get AIDS.
Scientists divide HIV into two types based on its genetic sequence: HIV-1 and HIV-2.
And these two types of HIV lead to different clinical manifestations of AIDS.
At present, some people who fear AIDS put forward to suffer from the so-called “Yin Zi disease”, that is, in addition to the above two types of another type of virus infection, research institutions at home and abroad after a large number of studies, confirmed that “Yin Zi disease” does not exist.

I. HIV-1: the “main cause” of the global AIDS epidemic
HIV-1 is the main type leading to the global epidemic of AIDS, including China, the vast majority of countries are prevalent virus HIV-1.
In China, the vast majority of AIDS patients we see infected with HIV-1.
The symptoms it causes are the “classic” symptoms we often see.
These symptoms fall into three main categories.
The first type is HIV-1, which grows and reproduces in the human body. The onset of AIDS will occur such as fever, diarrhea, night sweating and unexplained weight loss lasting for more than a month.
The second type is AIDS patients due to the decline of immunity is very serious, prone to a variety of infectious diseases, known as opportunistic infection, among which the most common is pneumocystis carinii pneumonia (once known as pneumocystis carinii pneumonia, pneumocystis carinii pneumonia).
The third type is also caused by a weakened immune system in AIDS patients, who are prone to developing tumors, most notably Kaposi’s sarcoma and non-Hodgkin’s lymphoma.
For the treatment of this type of AIDS, the medical community has a very interesting name called “cocktail therapy”, which is like making a cocktail, several different antiviral drugs according to the reasonable dose and course of treatment, together for the control of the growth and reproduction of the virus, so as to effectively control AIDS.

II. HIV-2: Virus confined to a few regions
In 1986, HIV-2 was first isolated from human in West Africa (West Africa). At present, HIV-2 is mainly distributed in West Africa and Western Europe. There are also a small number of cases in North America, and a few infected people have been found in some parts of China.
The ability of HIV-2 to infect and cause AIDS is low.
Some people infected with HIV-2 appear to have AIDS-like symptoms, but the vast majority do not.
If you have the following related behaviors or manifestations, you need to pay attention to whether you are infected with HIV-2, and promptly go to a regular hospital to seek help from a doctor.
West Africa, and are at high risk of HIV infection, such as multiple sexual partners, intravenous drug use, etc.
There were sexual partners from West Africa.
He received blood products from West Africa.
The mother was infected with HIV-2.
There were the following suspected opportunistic infections, but HIV-1 test was negative: pneumocytosiosis, tuberculosis, toxoplasmosis, cytomegovirus infection, and bird-intracellular mycobacterium complex infection.
Because HIV-2 shares the same route of transmission as HIV-1, people infected with HIV-2 need to follow the same preventive measures as HIV-1.
In addition, it is possible for a person to be infected with both HIV-1 and HIV-2.
