Variations in the incidence rates from state to state are influenced by epidemic patterns, particularly the occurrence of enteroviral outbreaks. Dissimilar rates may also reflect dissimilar reporting practices.

The 14 outbreaks of foodborne botulism in 1980 involved 18 people and were all related to home-canned or home-processed foods. There were 11 males and 7 females representing 10 states. Nine outbreaks were due to type A, 3 to type B, and 2 to type E toxin.

BOTULISM (Infant) – Reported cases and deaths by year,

United States, 1975-1980

[blocks in formation]

There were 68 cases of infant botulism; 36 males and 32 females, ranging in age from 3 weeks to 38 weeks. Thirty-three cases were due to type A toxin, 35 to type B toxin. One death was reported among infant botulism cases. The large increase in cases of infant botulism in 1980 may be due to an increased number of reported cases from one state (California).

For 1980, 183 cases of brucellosis were reported to CDC. The reported occurrence of brucellosis in the United States sharply decreased from 1947 (5,000 cases) until 1965. The downward trend has subsequently continued, but at a slower rate. The mean annual occurrence was 239 cases for 1966-1970, 226 for 1971-1975, and 221 for 1976-1980.

Chickenpox continued to be the second most frequently reported infectious disease in the United States. The seasonal pattern has remained constant; the peak incidence rate for 1980 was reached between March and May.
