1. What is HIV/AIDS? Acquired Immunodeficiency Syndrome (AIDS) is a disease caused by Human Immunodeficiency Virus (HIV). AIDS is a major concern in almost every country in the world. The World Health Organization (WHO) estimates that the cumulative number of AIDS cases in the world is up to 2.5 million persons. AIDS is the sixth leading cause of death among people aged 25 - 44 in the United States.

2. The infection of HIV/AIDS in many countries Globally, 85% of HIV transmission is through heterosexual intercourse. In the United States, approximately one-third of new diagnoses appear to be related to heterosexual transmission. Male-to-male sexual contact still accounts for more than half of new diagnoses in the U.S. Intravenous drug use contributes to the remaining cases. Because the diagnosis may occur years after infection, it is likely that a higher proportion of recent infections are due to heterosexual transmission. Infections in women are increasing. Worldwide, 42% of people with HIV are women. In the United States, approximately 25% of new diagnoses are in women, and the proportion is rising. At the end of 2010, an estimated 91,500 people in the United Kingdom were living with HIV and around 1 in 4 did not know they were infected. The World Health Organization (WHO) estimates that around 34 million people in the world are living with HIV. The virus is particularly widespread in sub-Saharan African countries, such as South Africa, Zimbabwe and Mozambique.
