Portions of Davenport University’s student center, gymnasium, and a dormitory are closed for extensive cleaning after teenagers on campus for a cheerleading camp were affected by an outbreak of norovirus.

About 35-40 high school girls were affected by the outbreak, which began late Tuesday or early Wednesday. They suffered diarrhea, vomiting and stomach cramps, according to Kent County Health Department spokeswoman Lisa LaPlante, though none of the victims required medical treatment or hospitalization.

The girls were attending a cheerleading camp that began Tuesday, LaPlante says.
Davenport officials believe the virus was spread through hand-to-hand contact — likely when the girls were passing pom-poms. The health department has ruled out the likelihood of foodborne transmission.
