HIV Transmission: Myths and Facts for Parents - Internal Medicine

Understanding HIV transmission is crucial for dispelling myths and ensuring that individuals, especially parents, are informed about the risks and facts surrounding the virus. Let's address your questions and provide some clarity on the matter.

1. If parents do not have HIV, will their child also not have HIV?
In general, if both parents are HIV-negative and have not engaged in high-risk behaviors (such as unprotected sex with an HIV-positive individual or sharing needles), the likelihood of their child being HIV-positive is extremely low. Vertical transmission (from mother to child during pregnancy, childbirth, or breastfeeding) is a primary route of HIV transmission, but this only occurs if the mother is HIV-positive. Therefore, if both parents are confirmed to be HIV-negative, the child cannot be born with HIV. However, it’s important to note that HIV can be transmitted through other means, such as sexual contact or sharing needles, so maintaining a healthy lifestyle and avoiding high-risk behaviors is essential.

2. Regarding oral sex and the risk of HIV transmission:
Oral sex is generally considered to be a lower-risk activity for HIV transmission compared to vaginal or anal sex. However, it is not entirely risk-free. The risk of HIV transmission through oral sex can increase if there are cuts, sores, or bleeding gums in the mouth of the person performing oral sex, or if the receiving partner has an open wound or sore on their genitals. In your case, if you engaged in oral sex with your cousin but did not ejaculate in his mouth, the risk of HIV transmission remains low, especially if both of you are HIV-negative and have not engaged in other high-risk behaviors.
It's also important to understand that HIV is not transmitted through saliva, so casual contact, such as kissing or sharing utensils, does not pose a risk for HIV transmission. The virus is primarily found in blood, semen, vaginal fluids, rectal fluids, and breast milk, and transmission typically occurs through direct contact with these fluids.


Additional Considerations:
- Testing and Awareness: If there are concerns about potential exposure to HIV, it is advisable to get tested. Many healthcare providers offer HIV testing as part of routine health check-ups, and it is a simple blood test. If you have engaged in any activities that could be considered high-risk, regular testing is a good practice.


- Understanding HIV Testing: HIV tests typically check for antibodies to the virus or the virus itself. The most common initial test is the ELISA (Enzyme-Linked Immunosorbent Assay), which is followed by confirmatory tests like the Western Blot if the initial test is positive. If you have concerns about the window period (the time between potential exposure to HIV and the point when the test will give an accurate result), it is important to discuss this with your healthcare provider.

- Education and Prevention: Educating yourself and others about HIV transmission can help reduce stigma and promote safer practices. Using protection during sexual activities, such as condoms, can significantly reduce the risk of HIV transmission.

In conclusion, if both parents are HIV-negative, the child will not have HIV. Oral sex carries a lower risk of transmission, especially if there are no bodily fluids exchanged. It is always best to stay informed, practice safe behaviors, and consult with healthcare professionals regarding any concerns about HIV or other sexually transmitted infections.
