This is typically followed by a prolonged period without symptoms.

Genetic research indicates that HIV originated in west-central Africa during the early twentieth century. Since its discovery, AIDS has caused nearly 30 million deaths as of As ofapproximately 34 million people have contracted HIV globally. AIDS is considered a pandemic —a disease outbreak which is present over a large area and is actively spreading.

There are three main stages of HIV infection: Acute infection, clinical latency and AIDS.
Many individuals develop an influenza like illness or a mononucleosis-like illness weeks post exposure while others have no significant symptoms. Some people also develop opportunistic infections at this stage. Gastrointestinal symptoms such as nausea, vomiting or diarrhoea may occur, as may neurological symptoms of peripheral neuropathy or Guillain-Barre syndrome.
The duration of the symptoms varies, but is usually one or two weeks. HIV is transmitted by three main routes: There is no risk of acquiring HIV if exposed to feces, nasal secretions, saliva, sputum, sweat, tears, urine, or vomit unless these are contaminated with blood. There is some evidence to suggest that female protection may provide an equivalent level of protection.
By contrast, use of the spermicide nonoxynol-9 may increase the risk of transmission due to its tendency to cause vaginal and rectal irritation. Whether it protects against male- to-female transmission is disputed and whether it is of benefit in developed countries and among men who have sex with men is undetermined.
Some experts fear that a lower perception of vulnerability among circumcised men may result in more sexual risk-taking behavior, thus negating its preventive effects. Women who have undergone female genital cutting have an increased risk of HIV.
Programs encouraging sexual abstinence do not appear to affect subsequent HIV risk. Evidence for a benefit from peer education is equally poor. Comprehensive sexual education provided at school may decrease high risk behavior.
It is not known if treating other sexually transmitted infections is effective in preventing HIV. This primarily involves the use of a combination of antivirals during pregnancy and after birth in the infant but also potentially includes bottle feeding rather than breastfeeding.
If replacement feeding is acceptable, feasible, affordable, sustainable and safe, mothers should avoid breast-feeding their infants, however exclusive breast-feeding is recommended during the first months of life if this is not the case.
If exclusive breast feeding is carried out, the provision of extended antiretroviral prophylaxis to the infant decreases the risk of transmission.
