Which statement about sexually transmitted infections (STIs) is accurate?

• A. An individual can have only one STI at a time.
• B. STIs may be present without any overt or observable signs or symptoms.
• C. Unlike other communicable diseases, STIs have no incubation period.
• D. Following recovery from an STI, an individual develops lifelong immunity to that STI.

Answer: (B)

STIs can be present without obvious signs or symptoms, so a person may be infected and contagious even when they feel perfectly healthy. This happens often with infections like chlamydia, HPV, or gonorrhea, especially early on, which is why regular screening and safe-sex practices are so important for sexually active individuals. The idea that you must have symptoms to be infected is not accurate; many people have no symptoms but can still transmit the infection to others. It’s also not true that you can have only one STI at a time or that there’s no incubation period. Co-infections can occur, and most STIs have an incubation period between exposure and when symptoms might appear. Additionally, recovery from an STI does not guarantee lifelong immunity; you can be reinfected with the same STI or acquire a different one in the future, which is why ongoing prevention and testing are essential.
