According to the International Journal of Occupational and Environmental Health: "Returning to school after vacations substantially increases the risk of hospital admissions for asthma in children, and this has considerable public health and economic impact."
Researchers examined NY State asthma hospitalizations from 1991-2001 and found a 20% to 300% increase in student asthma admissions associated with returning to school from school vacations.
The most significant increases were associated with students returning from summer vacation and for children in the 5-11 age range.
