ic bacteria. In 2019, there were 616,392 reported cases of gonorrhea in the United States, with an overall increased rate 5.7% from 2018 to 2019. Among those approximately 600,000 cases, it is estimated that 0.5-3% of gonorrheal infections result in gonococcemia. This condition is more common in women, affecting approximately 2.3-3% of women with gonorrhea and 0.4-0.7% of men. This discrepancy is explained by increased incidence of silent gonorrheal infections in females and an increased rate of transmission to females that have sexual intercourse with infected males. Gonococcemia also occurs more frequently in pregnant women, those with recent menstruation, and those with IUDs.

Pathogenesis

''Neisseria gonorrhoeae'' is transmitted during sexual contact with an infected individual. The bacteria invade the non-ciliated columnar epithelium of the urogenital tract, oral mucosa, or anal mucosa following exposure. Invasion of the host cells is made possible due to
