Kawasaki Disease Linked to Wind Currents
Written by Michael Chang

Scientists have found that wind currents may worsen Kawasaki disease, a condition that causes inflamed blood vessels. If further research confirms this, Kawasaki disease would be the first documented illness in which long-range wind transportation plays a significant role in creating infections, giving researchers a breakthrough on a 40-year-old medical mystery that has confounded even genetic studies...

Japanese researchers noticed a similar pattern. Together, they worked with a group of climate scientists who started to analyze atmospheric data.

What the climate researchers found was an association with the direction of wind circulating in the troposphere at heights of 3,000 meters, Burns says. When those wind currents blew in one direction, across Japan, then across the Pacific, to the West Coast and Hawaii, the number of U.S. cases increased. When the wind blew in the opposite direction, the number of cases fell.

The data was so overwhelming Burns and her team thought it couldn't be coincidental. If the theory that Kawasaki disease is true, it could open up a whole new understanding into how other airborne viruses are spread. No human disease has ever been shown to cross an ocean by wind and still remain infectious.

The causal agent of Kawasaki disease (KD) remains unknown after more than 40 years of intensive research. The number of cases continues to rise in many parts of the world and KD is the most common cause of acquired heart disease in childhood in developed countries. Analyses of the three major KD epidemics in Japan, major non-epidemic interannual fluctuations of KD cases in Japan and San Diego, and the seasonal variation of KD in Japan, Hawaii, and San Diego, reveals a consistent pattern wherein KD cases are often linked to large-scale wind currents originating in central Asia and traversing the north Pacific. Results suggest that the environmental trigger for KD could be wind-borne. Efforts to isolate the causative agent of KD should focus on the microbiology of aerosols.
