New York endured poor air quality in the early weeks of June due to smoke from Eastern Canadian wildfires making the air quality index unhealthy across the state. 

Daily mean PM 2.5 values were calculated and compared with the baseline value. 

The asthma-associated emergency department visits were recorded from the Electronic Syndromic surveillance system. 

They concluded that increased concentration of PM led to a three-fold increase in asthma-associated ED visits among older children and young adults.  

This study alerts physicians and public health experts towards low-risk communication and enhanced focus on high-risk individuals, devising effective wildfire smoke response plans.
