Answer

To determine which of the following does not belong to STDs (Sexually Transmitted Diseases), we need to analyze each option provided.

1. **Gonorrhea**: This is a sexually transmitted disease caused by the bacterium *Neisseria gonorrhoeae*. It is primarily transmitted through sexual contact. Therefore, gonorrhea belongs to STDs.

2. **Syphilis**: This is another sexually transmitted disease caused by the bacterium *Treponema pallidum*. It is also transmitted through sexual contact, making syphilis a part of STDs.

3. **AIDS**: Acquired Immunodeficiency Syndrome (AIDS) is caused by the Human Immunodeficiency Virus (HIV). It is transmitted through sexual contact, blood, and from mother to child during childbirth or breastfeeding. Thus, AIDS is classified as an STD.

4. **Dengue**: Dengue fever is caused by the dengue virus, which is transmitted through the bite of infected mosquitoes. It is not transmitted through sexual contact, hence it does not belong to STDs.

After analyzing all the options, the answer is **Dengue**, as it is not classified as a sexually transmitted disease.
