HIV is a virus that primarily attacks CD4-positive (CD4+) T-helper cells, which are white blood cells in the body's immune system.



These cells, also known as CD4 cells, T-helper cells, or T4 cells, are critical for recognizing pathogens that enter the body and mounting an immune response to combat them. Without treatment, HIV invades and kills CD4 cells, reducing the immune system's ability to fight infections and illnesses.

In people who are at high risk, there is a medical technique that greatly lowers the likelihood of contracting HIV. Prep, also known as pre-exposure prophylaxis, is an antiretroviral medication that helps people who are HIV-negative to remain HIV-free even if they have sex with HIV-positive or unidentified partners without using a condom.



"High risk" in this context refers to having one or more sexual partners who are HIV positive. It may also refer to engaging in sexual activity in… Continue

There are medical interventions that significantly reduce the risk of HIV infection for those who are at high risk of developing it. Pre-exposure prophylaxis, or PrEP, is the term used. PrEP is an antiviral drug that helps HIV-negative persons maintain their HIV-free status even if they have sexual contact without wearing a condom with an HIV-positive or unknown partner.



In this instance, having one or more sexual partners who are HIV + is considered to be "high risk." As well as any… Continue
