It is easier to spread the influenza virus (flu) than previously thought, according to a new University of Maryland-led study released today. People commonly believe that they can catch the flu by exposure to droplets from an infected person’s coughs or sneezes or by touching contaminated surfaces. But, new information about flu transmission reveals that we may pass the flu to others just by breathing.

Extreme heat and heavy rainfall are related to increased risk of hospitalization for asthma in Maryland, according to a study by the University of Maryland School of Public Health researchers. Based on over a decade of asthma hospitalization data (115,923 cases from 2000-2012), researchers observed a higher risk of asthma hospitalization after extreme heat or extreme precipitation events. The increases in risk were particularly high during the summer months. Their findings are published in the journal Environmental Health.
