The World Health Organization recommends treating all children less than 5 years of age; children above 5 are treated like adults.Measures to prevent opportunistic infections are effective in many people with HIV/AIDS.
Upon entry into the target cell, the viral RNA genome is converted (reverse transcribed) into double-stranded DNA by a virally encoded reverse transcriptase that is transported along with the viral genome in the virus particle.
The resulting viral DNA is then imported into the cell nucleus and integrated into the cellular DNA by a virally encoded integrase and host co-factors.
Because of its relatively poor capacity for transmission, HIV-2 is largely confined to West Africa.
After the virus enters the body there is a period of rapid viral replication, leading to an abundance of virus in the peripheral blood.
Blood-borne transmission can be through needle-sharing during intravenous drug use, needle stick injury, transfusion of contaminated blood or blood product, or medical injections with unsterilized equipment.
The risk from sharing a needle during drug injection is between 0.63 and 2.4% per act, with an average of 0.8%.
and is the cause of the majority of HIV infections globally.
The lower infectivity of HIV-2 as compared with HIV-1 implies that fewer people exposed to HIV-2 will be infected per exposure.
The most effective vaccine trial to date, RV 144, was published in 2009 and found a partial reduction in the risk of transmission of roughly 30%, stimulating some hope in the research community of developing a truly effective vaccine.Tags: Adult Dating, affair dating, sex dating
