The higher the concentration of HIV in semen or genital fluids, the more likely it is that HIV will be transmitted to a sex partner. To understand this, it is important to recognize that HIV is primarily transmitted through direct contact with certain body fluids, such as blood, semen, l fluids, and breast milk.
In the case of sexual transmission, the concentration of HIV in the infectious body fluids plays a crucial role. HIV can be present in various concentrations depending on the stage of infection, viral load, and individual factors.
To determine the concentration of HIV in semen or genital fluids, a specific laboratory test called a viral load test is performed. This test measures the amount of HIV genetic material (RNA) in these bodily fluids. The viral load is reported as the number of HIV RNA copies per milliliter (copies/mL).
Higher viral load, which indicates a higher concentration of HIV in the fluids, is associated with increased HIV transmission risk. It means there are more HIV particles present, making it more likely to pass the virus to a sex partner during unprotected sexual activity.
It is important to note that even when the viral load is undetectable, meaning the concentration of HIV in the blood is very low, the possibility of transmission still exists, although the risk is significantly reduced. Using additional prevention methods like consistent condom use and pre-exposure prophylaxis (PrEP) can further reduce the risk of HIV transmission.
