High-level ambient particulate matter before influenza attack with increased incidence of Aspergillus antigenemia in Southern Taiwan, 2016.

We found significant correlation between the incidence of severe influenza and Aspergillus antigenemia among medical intensive care unit patients for 7-month observation (coefficient γ=0.976, p<0.001). High-level ambient pollution was noticed for 2 months before the epidemic, highlighting that influenza patients might coinfect with aspergillosis in the community.
