Adenovirus Resources

The University of Maryland has received reports of students with confirmed Adenovirus-associated illness, and are saddened that one of those students recently passed away as a result of the illness. Adenoviruses are common causes of colds, but there are strains that can cause more serious illness. We urge our community to take seriously this strain of a common virus. We have compiled the information below to assist students, faculty, and staff with taking preventive measures and provide information about the steps our university has taken.
