The first global health day, known as World AIDS Day on December 1 each year, is supported by people living with HIV worldwide. They commemorate the deceased and fight together for a cure.  World AIDS Day was founded in 1988 to raise awareness of the disease and provide support to those who live with it. In its 30th year the theme of World AIDS Day 2018 is "Knowing Your Status" under the United Nations Joint Program on HIV and AIDS (UNAIDS). The topic is part of an effort to encourage people to get tested because thousands of people living with HIV do not even know it.
While HIV and AIDS are generally used interchangeably, the terms are not identical. The Human Immunodeficiency Virus, the official name for HIV, is a virus that causes an acquired immunodeficiency syndrome that is reduced to AIDS. After a person becomes infected with HIV, the immune system is further weakened, with AIDS being the last stage of the infection. While all AIDS-infected people are suffering from HIV, not every HIV-infected person falls ill with AIDS.
The first official report on the AIDS epidemic was in the form of the Weekly Report on Morbidity and Mortality (MMWR) of the Centers for Disease Control and Prevention (CDC). on June 5, 1
By the end of 1981, 270 cases of severe immunodeficiency had been reported in gay men and 121 of them died. 
Hospitals specifically intended for the treatment of AIDS sufferers were first opened in September 1982 year that the term AIDS was used for the first time.
Originally considered a disease that affects only men who are gay, the CDC reported on December 10, 1982, that an infant was diagnosed with AIDS suspected of having become infected after a blood transfusion. In January 1983, the CDC reported that women with AIDS-positive sexual partners also contracted the disease.
In the same year, the MMWR report stated that AIDS can be transmitted sexually or through blood. It also excluded the spread of the disease through accidental contact, food, water, air or environmental sources.
Prior to an epidemic, Margaret Heckler, then secretary of the Department of Health and Human Services, recognized in 1984 the cause of AIDS being the retrovirus HTLV-III, and to be predicted, a vaccine would be found within two years. Thirty-four years later, there is still no vaccine against AIDS.
The United States was far from being the only country dealing with the AIDS crisis, and in 1987 became the first disease debated at the United Nations General Assembly. In the same year, the first antiretroviral drug, zidovudine (AZT), was approved.
