Over the past 10 years, African governments—through national AIDS control programs—international development agencies, private voluntary organizations, and other nongovernmental groups across Africa have devoted resources, time, and energy to developing low-cost interventions to arrest the spread of HIV and AIDS.

Messages informing people about the danger of AIDS are regularly broadcast on radio and television, published in newspapers, displayed on billboards, and performed by local entertainers.


HIV is spread primarily by unprotected sex including anal and oral sex , contaminated blood transfusions , hypodermic needles , and from mother to child during pregnancy , delivery, or breastfeeding. Methods of prevention include safe sex , needle exchange programs , treating those who are infected , as well as both pre- and post-exposure prophylaxis. HIV made the jump from other primates to humans in west-central Africa in the early-to-mid 20th century.

Tailored estimation methods were used to produce final estimates of mortality. Years of life lost YLLs were calculated by multiplying the mortality rate by population by age-specific life expectancy. Years lived with disability YLDs were computed as the prevalence of a sequela multiplied by its disability weight. The rate of YLDs increased from 1. To reverse this trend and achieve epidemic control, EMR countries should strengthen HIV surveillance, and scale up HIV antiretroviral therapy and comprehensive prevention services. More than 1.

Explaining HIV and AIDS

HIV is a virus that targets and alters the immune system, increasing the risk and impact of other infections and diseases. Without treatment, the infection might progress to an advanced stage called AIDS. The life expectancy of a person with HIV is now approaching that of someone who tests negative for the virus, provided that the person takes medications called antiretroviral therapy on an ongoing basis. These are types of T cell — white blood cells that circulate, detecting infections throughout the body and faults and anomalies in other cells. HIV targets and infiltrates CD4 cells, using them to create more copies of the virus. This increases the risk and impact of opportunistic infections and some types of cancer.
