Why in News:
- A European study of nearly 1,000 gay male couples — who had sex without condoms where one partner had HIV and was taking anti-retroviral drugs to suppress it — has found the treatment can prevent sexual transmission of the virus.
- After eight years of follow-up of the so-called serodifferent couples, the study found no cases at all of HIV transmission within couples
- The study proves, the researchers said, that using anti-retroviral therapy to suppress the AIDS virus to undetectable levels also means it cannot be passed on via sex,
- The findings provide conclusive evidence for gay men that the risk of HIV transmission with suppressive ART is zero
- The study, published in the Lancet medical journal assessed the risk of HIV transmission between serodifferent gay male couples — where one partner is HIV-positive and one is HIV-negative — who do not use condoms.
- It also found zero risk.
- The word AIDS stands for Acquired Immuno Deficiency Syndrome. This means deficiency of immune system acquired during the lifetime of an individual indicating that it is not a congenital disease [disease or abnormality present from birth]. ‘Syndrome’ means a group of symptoms.
- AIDS was first reported in 1981 and in the last twenty-five years or so, it has spread all over the world.
- AIDS is caused by HIV, a retrovirus that attacks the immune system. The virus destroys CD4+ T cells, a type of white blood cell that’s vital to fighting off infection. AIDS is treated with antiretroviral drugs. These drugs suppress HIV but don’t completely eliminate the virus from the body.
- The Union Ministry of Health and Family Welfare launched the National Strategic Plan 2017-24 aimed at eradicating HIV/AIDS by 2030. It was launched on the occasion of World AIDS Day (1st December).
- Mission SAMPARK was also launched to trace those who are Left to Follow Up and are to be brought under Antiretroviral therapy (ART) services.
- 90:90:90 Strategy It is a new HIV treatment narrative of UNAIDS programme which has set targets of 90% of all people living with HIV will know their HIV status (90% diagnosed), 90% of all people with diagnosed HIV infection will receive sustained antiretroviral therapy (90% on HIV treatment) and 90% of all people receiving antiretroviral therapy will have viral suppression (90% suppressed).
