Which of the following diseases does NOT typically present with visible symptoms in all patients?

AIDS does not typically present with visible symptoms in all patients. This condition progresses over time and can remain asymptomatic for many years after a person is infected with HIV, the virus that causes AIDS. Individuals may not exhibit any symptoms until the immune system is significantly compromised, which makes it difficult to diagnose in the early stages without testing.

In contrast, the other conditions listed—syphilis, herpes II (also known as genital herpes), and gonorrhea—often have more distinct and visible symptoms in many individuals. For example, syphilis can cause sores and rashes that are typically observable, and herpes II frequently results in noticeable painful blisters or sores during outbreaks. Gonorrhea often prompts symptomatic effects like a discharge or painful urination in infected individuals. Therefore, AIDS stands out as the disease that can be asymptomatic, making it distinct among the options provided.
