HIV infection

In 1981, the human immunodeficiency virus was first discovered in the United States. It is a lentivirus that infects the cells of the human immune system, a type of retrovirus. There are no effective treatments for fatal infectious diseases. The virus destroys the body's immune capabilities, leading to the loss of the immune system's resistance, which causes various diseases and cancers to survive in the human body, and in the end, leads to AIDS (acquired immune deficiency syndrome). It has caused nearly 12 million deaths worldwide and more than 30 million people became infected. It will integrate into the host cell's genome after infection, and current antiviral treatments cannot eradicate the virus. At the end of 2004, there were about 40 million people who were infected and co-existed with the human immunodeficiency virus worldwide. Sub-Saharan Africa is still the most prevalent epidemic, followed by South Asia and Southeast Asia. East Asia, Eastern Europe, and Central Asia. On July 25, 1986, the World Health Organization (WHO) issued a bulletin, and the International Conference on the Classification of Viruses decided to rename HIV to Human Immunodeficiency Virus (HIV) for short. HIV infection means infection with the virus.
