Abstract
Influences of climate on the occurrence of infectious skin diseases were investigated statistically by collecting the clinical records of two hospitals around Fukuoka district during 3 years. The results were them examined with the statistical methods (X2 test and Fisher’s exact probability test) and the following results were shown to be significant with a confidence limit of 95%.
(1) Trichophytia pompholyciformis, Trichophytia eczematosa marginata, Pityriasis versicolor and Impetigo bullosa increased with high air temperature (above 16.2°C), high humidity (above 71.8%), long duration of sunshine (above 169.2h) and low atmospheric pressure (under 1014.6mb).
(2) Multiple sweatgland abscesses of infants showed almost same tendency as (1) except that no correlation was observed with humidity.
(3) Folliculitis increased with high temperature and long duration of sunshine.
(4) Varicella increased with low temperature and short duration of sunshine.
(5) Herpes zoster increased with much precipitation (volume of rain, above 116.1mm) and low atmospheric pressure. (Limits to judge each climatic factors “high” or “low” were their mean value; temperature 16.2°C, humidity 71.8%, duration of sunshine 169.2h, atmospheric pressure 1014.6mb, precipitation 116.1mm)
