The isolation rates of the 2 predominant species continue to be reversed for the American Indian reservations where 58% of the isolates were S. flexneri and 41% S. sonnei. In contrast to Salmonella, for which the highest rate of isolation occurred in the 2-month age group, the highest isolation rate for Shigella occurred in the 2-year-old age group. Cases per 100,000 Population SYPHILIS (Primary and secondary) - Reported civilian case rates by year, Syphilis is the third most frequently reported communicable disease in the United States. The trend of reported primary and secondary syphilis has changed directions several times during the 39 years these data have been available. Reported primary and secondary syphilis cases totaled 27,204 for 1980, an increase of 9.4% from the number reported for 1979. The variations in reported case rates of primary and secondary syphilis for states reflect differences in many variables, including case-finding activity, availability of public clinic facilities, program priorities, and reporting practices, as well as difference in attack rates. |
