When it comes to the risk of HIV transmission through unprotected oral sex, it's important to understand the nuances involved. Oral sex is generally considered to be a lower-risk activity for HIV transmission compared to vaginal or anal sex. However, certain factors can increase the risk, such as the presence of cuts or sores in the mouth, bleeding gums, or the presence of other sexually transmitted infections (STIs).

In your case, since you and your girlfriend have had unprotected oral sex, and she is now exhibiting symptoms that could be associated with acute HIV infection—such as nausea, vomiting, fatigue, body aches, and rashes—it's crucial to take her symptoms seriously. While these symptoms can be indicative of various conditions, including other viral infections or STIs, they are also consistent with the acute retroviral syndrome (ARS) that can occur in the early stages of HIV infection.

Given that your girlfriend is experiencing these symptoms, it is advisable for both of you to get tested for HIV as soon as possible. The Centers for Disease Control and Prevention (CDC) recommends that individuals who have had potential exposure to HIV get tested. Testing is especially important if symptoms are present, as early detection can lead to timely treatment and better health outcomes.

For HIV testing, there are different types of tests available, including antibody tests, antigen/antibody tests, and nucleic acid tests (NAT). Antibody tests typically take longer to detect HIV, as they rely on the body producing antibodies in response to the virus, which can take weeks to months. Antigen/antibody tests can detect HIV earlier, usually within 18 to 45 days after exposure. NAT can detect HIV even earlier, typically within 10 to 33 days after exposure, but it is more expensive and not as widely available.

In your situation, if you are within the window period for testing, it is recommended to get tested immediately and then follow up with additional testing after the window period has passed to confirm the results. If your girlfriend's symptoms persist or worsen, she should seek medical attention promptly.

In addition to HIV testing, it may also be wise to consider testing for other STIs, as the presence of one STI can increase the risk of contracting or transmitting HIV. Regular STI screenings are an important aspect of sexual health, especially if engaging in unprotected sexual activities.

Lastly, it is essential to have open and honest communication with your partner about sexual health, testing, and any concerns you may have. This can help both of you make informed decisions about your sexual practices and health moving forward.

In summary, given the circumstances and your girlfriend's symptoms, it is highly recommended that both of you get tested for HIV and other STIs as soon as possible. Early detection and treatment are key to managing health outcomes effectively.
