Kawasaki research points to ill wind blowing

A US-led international study has highlighted a correlation between wind direction and three KD epidemics in Japan, which peaked in April 1979 (6700 cases), May 1982 (16,100) and March 1986 (14,700). 

“The numbers rapidly mounted all over Japan when winds turned and blew in a south-westerly direction,” Professor Jane Burns from the division of allergy, immunology and rheumatology at the University of California said in a media statement.

Similar correlations were also seen between wind direction and KD incidence in San Diego and Hawaii, and “our findings suggest an environmental trigger for KD that could be wind-borne”.
