HIV prevention refers to practices that aim to prevent the spread of the human immunodeficiency virus (HIV). HIV prevention practices may be undertaken by individuals to protect their own health and the health of those in their community, or may be instituted by governments and community-based organizations as public health policies.
The HIV Prevention Trials Network conducted a clinical trial, HPTN 052, that analyzed the effectiveness of antiretroviral drugs on the HIV-1 virus. 1,783 HIV sero-discordant couples, or couples that consist of an HIV-positive individual and an HIV-negative partner, from nine different countries were a part of the study, 97% of the couples being ...
The National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP), formerly the National Center for HIV, STD, and TB Prevention (NCHSTP) is a part of the Centers for Disease Control and Prevention and is responsible for public health surveillance, prevention research, and programs to prevent and control human immunodeficiency virus (HIV) infection and acquired ...
Disease prevention relies on anticipatory actions that can be categorized as primal, [2] [3] primary, secondary, and tertiary prevention. [1] Each year, millions of people die of preventable causes. A 2004 study showed that about half of all deaths in the United States in 2000 were due to preventable behaviors and exposures. [4]
The abbreviation PrEP now typically refers to pre-exposure prophylaxis for HIV prevention, the use of antiviral drugs as a strategy for the prevention of HIV/AIDS. [2] PrEP is one of a number of HIV prevention strategies for people who are HIV negative but who have a higher risk of acquiring HIV, including sexually active adults at increased risk of contracting HIV, people who engage in ...
Although HIV PrEP medications are only available in oral tablet and injectable formulations, other formulations are being developed and studied. The emerging treatments expand HIV prevention strategies for women. For example, a vaginal gel formulation of tenofovir and an intravaginal ring releasing dapivirine are under investigation for ...
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.
ARVs work either by preventing the HIV virus from entering a human host cell, or by preventing its replication after it has already entered. [13] Examples of ARV drugs being tested for prevention include tenofovir, dapivirine (a diarylpyrimidine inhibitor of HIV reverse transcriptase) and UC-781. [14]
