Changing Epidemiology of Q Fever in Germany, 1947-1999

Wiebke Hellenbrand, Thomas Breuer, and Lyle Petersen
Robert Koch-Institut, Berlin, Germany

Figure 3. Seasonality of 24 sheep-associated community outbreaks in Germany, 1947-1969, 1970-1989, and 1990-1999. For each community outbreak in which sheep were implicated, the number of months' duration in each season was calculated. For each time period, the percentage of the total number of outbreak months occurring during each season was calculated. The "year-round" outbreak in Dettenhausen (Table 1) was excluded. Winter = January-March; spring = April - June; summer = July-September; autumn = October-December.
