Gonorrhea

The infection: Gonorrhea, caused by the bacteria Neisseria gonorrhoeae. Over 677,000 new cases in the U.S. were reported in 2020.
Symptoms and long-term effects: Painful urination and discharge in both women and men. Untreated, it can raise the risk of contracting other STDs, and it can also cause fetal complications, including miscarriage, if contracted during pregnancy.
How to treat it: Antibiotics generally work well, but an increasing number of cases are becoming resistant to the only frontline drugs available for it, leading to the emergence of so-called super gonorrhea.
