What type of treatment is likely indicated for STDs that are not caused by a virus?

In the case of sexually transmitted diseases (STDs) that are caused by bacteria or parasites, the appropriate form of treatment is antibiotics. These medications are specifically designed to target bacterial infections, effectively killing the bacteria or inhibiting their growth.

Common bacterial STDs include chlamydia, gonorrhea, and syphilis, all of which are treated with antibiotics to eliminate the pathogens from the body. It's important for individuals diagnosed with these infections to complete their antibiotic regimen to ensure the infection is fully cleared and to prevent complications or further transmission.

While antiviral treatments are significant for viral infections like HIV or herpes, they do not work on bacterial or parasitic STDs. Antigens and vaccines also play a role in disease prevention rather than treatment. Vaccines, such as those for HPV or hepatitis, can help prevent certain STDs but are not used to treat existing infections. Therefore, the targeted treatment approach for non-viral STDs is through antibiotics, making it the correct choice in this context.
