CASES PER 100,000 POPULATION

Gonorrhea Reported civilian case rates by year, United States, 1941-1980

Gonorrhea is the most frequently reported communicable disease in the United States. Beginning in 1966, reported gonorrhea cases increased at about 12% per year until 1973, for which 842,621 cases were reported. The sharp increase of reported cases in the late 1960s and early 1970s is thought to represent an actual increase in the occurrence of disease as well as improved case-detection procedures. Since 1973, when federally assisted state and local programs were implemented to control gonorrhea, the reported number of cases has plateaued at about 1 million cases per year: 1,004,029 cases were reported for 1980, only slightly less (-29) than the 1,004,058 cases reported for 1979. Even so, the case rate per 100,000 population decreased from 459.49 for 1979 to 443.27 for 1980. The leveling-off of reported cases since 1975 is thought to be due to the disease-intervention activities initiated in 1973.

A strain of gonococci resistant to all forms of penicillin has emerged-penicillinaseproducing Neisseria gonorrhoeae (PPNG). From March 1976 through December 1980, 1962 cases of PPNG were identified in 43 states, the District of Columbia and Guam. A significant proportion of PPNG cases were related to importation of infection from either Southeast Asia or the west coast of Africa. However, results for 1980 suggest an increasing occurrence of PPNG cases within the United States.

Proven major civilian outbreaks of PPNG occurred in four areas in 1980: Los Angeles, New York City, Washington, and Louisiana. Control efforts including intensive surveillance, case detection, treatment, and contact tracing have been able to contain all outbreaks, and most cases continue to be imported or linked to imported cases.
