The incidence of deaths due to botulism among water fowl in the Norfolk Broads, England, is closely related to two meteorological factors. These are the number of days in summer with a maximum air temperature of 21ยฐC or more, and the excess of water evaporation over rainfall in the months April, May

โฆ Synopsis
Analysis of the incidence of Redwater Fever, which is transmitted by the tick Ixodes ricinus, in the Tavistock area of South Devon over the years 1955-1967, showed a very significant correlation with maximum air temperature, provided that the periods January-May and June-September were considered separately. The response to temperature was 2-3 times greater in the "spring" than in the "autumn". An independent analysis of the disease data from the Lleyn peninsula of North Wales confirmed this conclusion.
