SARS-CoV-2 and HIV-1 have similarities—notably both are RNA viruses—but there are important differences. As a retrovirus, HIV-1 can insert a copy of its RNA genome into the host's DNA, making total eradication more difficult. [156] The virus is also highly mutable making it a challenge for the adaptive immune system to develop a response.
Universal precautions within the health-care environment are believed to be effective in decreasing the risk of HIV. [46] Intravenous drug use is an important risk factor and harm reduction strategies such as needle-exchange programmes and opioid substitution therapy appear effective in decreasing this risk.
AIDS Healthcare Foundation (AHF) is a Los Angeles-based 501(c)(3) nonprofit organization that provides HIV/AIDS prevention, treatment, and advocacy services.

HIV is a retrovirus that primarily infects components of the human immune system such as CD4 + T cells, macrophages and dendritic cells. It directly and indirectly destroys CD4 + T cells. [88] HIV is a member of the genus Lentivirus, [89] part of the family Retroviridae. [90] Lentiviruses share many morphological and biological characteristics.
As part of that pledge, leaders vowed to reduce annual new HIV infections to below 370,000 by 2025, but the report said in 2023 new infections were more than three times higher at 1.3 million.
When an infant is born to an HIV-infected mother, diagnosis of an HIV infection is complicated by the presence of maternal anti-HIV IgG antibody, which crosses the placenta to the fetus. Indeed, virtually all children born to HIV-infected mothers are HIV-antibody positive at birth, although only 15%-30% are actually infected.
This means staying home if you test positive for the virus—though isolation guidelines have changed quite a bit since SARS-CoV-2, the virus that causes illness with Covid-19, first emerged.
