How long is the window period for AIDS? Comprehensive interpretation of the origin of AIDS!

HIV is a virus that attacks the body’s internal organs. It makes T4 lymphoid tissue, the most important part of the human immune system, a target of attack and massively destroys T lymphoid tissue, leading to highly fatal internal failure. This virus is a lifelong infection in this area, disrupting the immune balance and making the human body a vector for various diseases. When the HIV immune system itself doesn't cause any disease, it doesn't cause any disease. After the HIV virus is destroyed, the human body loses the opportunity to replicate immune cells due to low resistance, thereby contracting other diseases, leading to various complex infections and death. The average incubation period of HIV in the human body is 12 to 13 years. Patients appear normal and can live and work without symptoms for many years before developing AIDS.

Scientific research has found that AIDS was first spread in West Africa. It was transmitted by an African man after having sex with other primates. At the time, the man had had sex with other primates and then with others of the same sex before he started suffering from AIDS.

An international research team composed of scientists from the United States, Europe and Cameroon said that they confirmed through field surveys and genetic analysis that human HIV-originated in wild chimpanzees, and that the virus likely evolved from the simian immunodeficiency virus SIV. . In fact, the origin of AIDS should be in Africa. In 1959 Congo was still a legal colony. An Aboriginal man emerging from the forest is invited to participate in a study on blood-borne diseases. After testing, his blood samples had been refrigerated for decades. Unexpectedly, decades later, the blood sample would become an important clue to solving the source of AIDS.

AIDS originated in Africa and then immigrated to the United States. On June 5, 1981, the Centers for Disease Control in Atlanta briefly introduced the medical histories of five AIDS patients in Morbidity and Mortality Weekly, which was the first time in the world that AIDS was officially recorded. In 1982, the disease was named AIDS. Soon after, AIDS spread rapidly to every continent. In 1985, a young foreigner traveling in China died soon after being admitted to Peking Union Medical College Hospital and was confirmed to have died of AIDS. This is the first time that AIDS has been discovered in China (see Zeng Yi: AIDS Epidemic Trends, Research Progress and Containment Strategies).

AIDS is a serious threat to human survival and has attracted the attention of the World Health Organization and governments of various countries. AIDS is spreading faster and faster around the world, seriously threatening human health and social development, and becoming the fourth largest killer of human health. Since AIDS was first recognized in June 1981, UNAIDS announced on May 30, 2006 that 65 million people worldwide have been infected with HIV, and 2.5 million of them have died. As of the end of 2005, there were 38.6 million people infected with HIV worldwide. That year, 4.1 million people were infected with HIV and 2.8 million died from AIDS. On July 29, 2008, UNAIDS released the "2008 AIDS Epidemic Report" on Tuesday. The report points out that in 2007, global AIDS prevention and control efforts made significant progress, and the AIDS epidemic eased for the first time. The number of people infected with HIV and HIV has increased compared with 2001, and the number of global AIDS deaths has declined from 27 million.

According to experts, it takes several years or even more than 10 years for a person infected with HIV to develop into an AIDS patient from the early stage of infection. Due to extremely low resistance, AIDS patients will be infected with a variety of infections, such as herpes zoster, oral fungal infection, tuberculosis, enteritis, pneumonia, encephalitis, etc. Malignant tumors caused by special pathogenic microorganisms often occur in the later stages until long-term consumption and systemic failure.

Despite the great efforts of many medical researchers around the world, there is currently no specific drug to treat AIDS and no effective vaccine to prevent it. At present, this "super cancer" with a mortality rate of almost 100% has been listed as a Class B notifiable infectious disease in my country and one of the infectious diseases monitored by border health. Therefore, we call it a ‘super terminal illness’.

How long can HIV live?

1. HIV can survive in a liquid environment at room temperature for 15 days.

2. If the blood is not dry, leave it at room temperature for 96 hours. Even if the HIV virus is a drop of blood the size of a pinhead, it will still be viable if it encounters fresh lymphocytes.

HIV can still enter and replicate, and is contagious.

3. Contaminated HIV will be contagious for at least 3 days.

4. The blood content of HIV is low and the vitality will be lost after 2 hours of natural drying.

5. The blood content of HIV is very high. Even if it is dried for 2 to 4 hours, once the culture medium is placed, lymphocytes can still enter and replicate when they encounter it.

Window symptoms of AIDS usually refer to the acute symptoms of AIDS. Because the window period is very short, from the day you are infected with HIV to the day you are tested. For ordinary people, the window period is 2-12 weeks.

In such a short period of time, the symptoms of AIDS are usually those of an acute infection.

After the HIV virus enters the human body, it will replicate in large quantities and begin to destroy the immune system. When lymphocytes are stimulated, some common acute symptoms occur. Such as fever, rash, lymphadenopathy, fatigue, sweating, nausea, vomiting, diarrhea, pharyngitis, etc. If you draw blood for testing, you may find that the number of white blood cells is normal, lymphocytes are reduced, and monocytes are increased. This phenomenon is the same as other viral infections or inflammations. Therefore, HIV infection cannot be diagnosed through routine blood tests. And some people have mild symptoms and normal blood tests.

Most infected people can be tested positive for HIV antibodies within 2 to 6 weeks by measuring whole blood, serum or plasma.

How long is the symptom window period of AIDS?

After infection with HIV, window symptoms may appear for two to four weeks and last for about two to six weeks. Symptoms are irregular and vary from person to person. Most people have symptoms, which are mild and often ignored. Then enters a long asymptomatic incubation period.

AIDS incubation period symptoms and AIDS incubation period

During the incubation period, there are usually no symptoms. The symptoms displayed are not serious and appear normal. Some patients develop symptoms such as rash and diarrhea during the incubation period, which is similar to the AIDS window period.

What are the symptoms of Window Assist?

Swollen lymph nodes, night sweats, headache, cough, long-term low-grade fever, rash, diarrhea, weight loss, cough, oral infection, muscle and joint pain, maculopapular rash, urticaria, stomach pain, Kaposi's sarcoma . These symptoms are common, the likelihood is difficult to quantify, can be complex, and completely individual.

Can AIDS window symptoms be diagnosed?

No. The AIDS window symptoms can be used as a reference but cannot be used for AIDS diagnosis. HIV symptoms are non-specific, and the truth can only be known through testing. If there is excessive risk behavior, it is recommended to conduct HIV testing through scientific testing methods. There are many ways to test for HIV. You can go to the local Center for Disease Control and Prevention to get tested, or you can order HIV test strips for self-testing. Yes, the testing process is simple and the results are quick, taking about 15 minutes. Early detection is of great significance to the diagnosis of AIDS. Reducing the psychological burden, even if it is positive, will help to seize the opportunity for treatment and prolong life.
