What are the three main types of STIs?

The three main types of sexually transmitted infections (STIs) are indeed bacterial, viral, and parasitic. This classification is important for understanding how these infections are transmitted, the symptoms they may cause, and the treatment options available.

Bacterial STIs, like chlamydia and gonorrhea, are caused by bacteria and can usually be treated effectively with antibiotics. Viral STIs, such as HIV, herpes, and HPV, are caused by viruses and, while some can be managed, they often require ongoing treatment and may not be curable. Parasitic STIs include infections like trichomoniasis, which are caused by parasites and can also be treated effectively, typically with specific medications.

Understanding these categories helps in public health education and prevention strategies, as each type of infection has different modes of transmission, treatment, and implications for health.
