Which one among the following is not a sexually transmitted disease?

Sexually transmitted infections (STIs) are diseases passed through sexual contact, including vaginal, anal, or oral sex [2]. Common examples include bacterial infections like gonorrhea and syphilis, and viral infections such as HIV, HPV, and Hepatitis B [4]. Specifically, gonorrhea is caused by the bacterium Neisseria gonorrhoeae, while syphilis is caused by Treponema pallidum [1]. Hepatitis B is a viral infection that can be transmitted through sexual contact or direct transfer of body fluids [4]. In contrast, scurvy is not an infectious or sexually transmitted disease; it is a nutritional deficiency disease caused by a lack of Vitamin C (ascorbic acid) in the diet. While the provided snippets focus on infectious diseases like malaria and dengue [3], scurvy remains a classic example of a non-communicable nutritional disorder, making it the correct answer as it is not an STI.
