42 years ago today, on May 9, 1983 (March 27, 1983 lunar calendar), AIDS began to spread around the world. A line drawing of 610 people who have died of AIDS in the city since December 1987 was drawn on the square in Dallas, USA, to warn of the spread of AIDS in the region. The National Epidemic Prevention Center of Atlanta reported on May 9, 1983 that people in the United States had AIDS (as of that day). 1,410 people, including 57.4% whites, 21.6% blacks, and 5.6% Haitians. In addition, 103 people in 16 countries including France, the Netherlands, Sweden, Belgium, and the United Kingdom also suffered from the disease. AIDS, also known as "AIDS" or Acquired Immune Deficiency Syndrome, is a serious cellular immune deficiency disease that is often combined with multiple opportunistic infections and malignant tumors. The pathogen is human T-cell virus type III, also known as lymphatic virus. This virus is mainly transmitted through sexual contact, and it is rapidly transmitted. The disease is dangerous and has a high fatality rate. Delegates from all over the world gathered in London in January and March 1988 to discuss the global impact of AIDS. They called on governments to take urgent action to control this disease spread through blood and other bodily fluids. On June 26, 1988, the 13th Gay and Lesbian Freedom Day, 300,000 AIDS patients marched in San Francisco. The banner in the picture reads: AIDS Patients Unite In June, another conference was held in Stockholm, bringing together more than 6,000 experts from 125 countries. However, the delegates heard bad news here: Despite a huge international communication research program, scientists have not found a cure. In light of this, experts are urging a campaign to raise public awareness of AIDS to prevent it from spreading from high-risk groups - homosexuals and intravenous drug users - to the wider population. AIDS is mainly spread through infected blood and other bodily fluids. It is estimated that about 5 million people in the world became infected with HIV in 1988, of whom 150,00 have developed AIDS. Experts estimate that this number will double by the end of the year, and that 1 million will join the ranks of the infected within the next five years. Although Africa is considered the region with the highest incidence, the United States has the largest number of people with AIDS in public reports. In response to the crisis, the United States established a presidential commission of inquiry, which endorsed a confidential list of all AIDS patients provided by doctors and recommended that state officials should inform the sexual partners of those who are sick. But this measure has caused controversy. It was clear that scientists were far from finding an effective cure for AIDS, and in the West, AIDS caused widespread discrimination against people with the disease and homosexuals. In 1990, the Sixth International AIDS Conference was held in San Francisco, and AIDS patients held the largest rally ever and held demonstrations to express their anger. The mayor of San Francisco vividly described the seriousness of the problem with numbers. In his opening speech, the mayor announced that in the 1980s, the number of people dying of AIDS in San Francisco was three times that of all the city's deaths in World War II, the Korean War, and the Vietnam War. Scientists are actively looking for a cure. The sheets of 1,800 AIDS patients covered the lawn in front of the White House
