Asthma in Houston (IMAGE) Rice University Caption A map produced for a study in the Journal of School Health shows where ambulances responded to elementary school zones in Houston from 2004 to 2013, as well as school nurse assignments. The study by Rice University researchers in collaboration with the city and Houston Independent School District details where and when students with asthma were most likely to suffer attacks that required emergency treatment over a 10-year span.
