Essential Sexual-Health Terms: U=U, PrEP, PEP, and STIs
U=U comes from the phrase “Undetectable = Untransmittable.” It means that a person living with HIV who maintains an undetectable viral load cannot pass…
Sexual health care is important for everyone, especially for the LGBTQIA+ community, who may face specific risks and require information tailored to their lifestyle. This article will cover and include terms related to sexually transmitted infections (STIs) that the LGBTQIA+ community should be aware of.
What we commonly hear as PrEP (Pre-Exposure Prophylaxis) is a medication that helps reduce the risk of contracting HIV. Before starting the medication, individuals must undergo blood and health tests. The medication should be taken at least 7 days before potential HIV exposure to allow the drug to build up in the body. We highly recommend using PrEP in combination with condoms to protect against both HIV and other sexually transmitted infections.
PEP
This is the name of the emergency medication (Post-Exposure Prophylaxis, PEP). Make sure to note down the name of this medication because if you’ve had a potential HIV exposure—whether due to a condom breaking or sex without a condom—you’ll need to use it. This medication is most effective in preventing HIV when taken within 72 hours of exposure, and the sooner you take it, the better!
Ureaplasma
Ureaplasma infections, which can be transmitted through sexual contact, are usually harmless. However, if the body is weakened, they can cause unwanted symptoms such as a burning sensation in the genital area during urination, discharge, and may even lead to testicular inflammation.
Hepatitis C Virus (HCV) is a common virus that is often transmitted through sex without a condom. If you contract the Hepatitis C virus, it increases your risk of developing hepatitis, liver cirrhosis, and even liver cancer.
Syphilis
Syphilis is one of the sexually transmitted infections (STIs) that has been increasingly prevalent each year. It can affect individuals of all genders if sexual activity is unprotected. In its early stage, syphilis causes painless sores known as chancre. If left untreated, it can progress to the secondary stage, leading to rashes, raised bumps resembling warts, appearing on the body, palms, soles of the feet, and genital area. If it reaches the final stage, it can cause severe complications such as paralysis, deafness, heart disease, and even organ failure.
Sexually transmitted infections (STIs) can be detected and treated early, so getting tested is key to maintaining good health. If you have the time, don't forget to get tested!
