A cluster of 28 students tested positive for influenza A since Oct. 24 at the University of Rhode Island (South Kingstown), the first known influenza outbreak of the state this year, according to the state’s department of health.
The state laboratory noted infection control procedures have been reviewed with the university, but there are no known common trends linking these students to the same dorms or classes.
