What is the lowest risk of HIV transmission?
Oral sex carries little to no risk for getting or transmitting HIV. Theoretically, transmission of HIV is possible if an HIV-positive man ejaculates in his partner’s mouth during oral sex. However, the risk is still very low, and much lower than with anal or vaginal sex.
What factors affect transmission of HIV?
What Are the Risk Factors for HIV?
- Having a sexually transmitted infection (STI), such as syphilis, genital herpes, chlamydia, or gonorrhea.

How long can you stay undetectable?
A person’s viral load is considered “durably undetectable” when all viral load test results are undetectable for at least six months after their first undetectable test result. This means that most people will need to be on treatment for 7 to 12 months to have a durably undetectable viral load.
Is it possible to test negative while your partner is positive?
A: It is quite common for one partner to test positive and the other negative, even if they have been having sex without condoms. Mostly this is explained by luck and the role of other risk factors. Over time, most people will catch HIV if they continue to be at risk.
Can I infect someone if my viral load is undetectable?
CDC Agrees That Person with Undetectable HIV Cannot Transmit the Virus. The agency has adopted the widely accepted position that an HIV-positive person with an undetectable viral load cannot pass the virus through unprotected sex. If you can’t detect it, you can’t transmit it.
What is a bad viral load?
Viral load is the term used to describe the amount of HIV in your blood. For example, a viral load of 10,000 would be considered low; 100,000 would be considered high. Viral load changes can be very large, so they are sometimes quantified using the powers of ten, or ‘log scale’.
What causes the viral load to go up?
An increase in viral load can occur for many reasons, such as: not taking antiretroviral medication consistently. the HIV has mutated (changed genetically) antiretroviral medication isn’t the right dose.
What is the normal CD4 count for a healthy person?

How long can you live with a low CD4 count?
A person’s CD4 count at the start of treatment remains one of the strongest indicators of life expectancy. The life expectancy between those whose CD4 count is less than 200 at the start of treatment is 8 years less than those whose count is over 200 at the same time.
Are there any known cases of HIV transmission?
The only known cases are among infants. Being bitten by a person with HIV. Each of the very small number of documented cases has involved severe trauma with extensive tissue damage and the presence of blood. There is no risk of transmission if the skin is not broken.
Is the risk of HIV transmission low after one exposure?
Some clients may see these numbers and think their risk of HIV transmission is low. Therefore, caution is needed when interpreting them. If these numbers are provided to clients, they should be accompanied by information that helps shed light on why the risk may be higher than it seems. Transmission can occur after one exposure.
Who is not guilty of criminal transmission of HIV?
In addition, under the law a person is not guilty of criminal transmission of HIV if the person exposed knew both that the infected person was HIV positive, and that he or she could be infected as a result, and consented to the action.
