Which of the following disease is not sexually transmitted?

Influenza is not a sexually transmitted disease. Influenza, also known as the flu, is a highly contagious viral infection that primarily spreads through respiratory droplets when an infected person talks, coughs, or sneezes. It can also spread by touching a surface contaminated with the virus and then touching one's mouth, nose, or eyes. Unlike gonorrhea, herpes, and syphilis, which are sexually transmitted diseases, influenza is not typically spread through sexual contact. While some viruses can be transmitted through sexual activity, influenza is not one of them. To prevent the spread of influenza, it is important to practice good hygiene, such as washing your hands frequently, covering your mouth and nose when coughing or sneezing, and staying home when you are sick. Additionally, getting an annual flu vaccine is the most effective way to protect against influenza.
