(Providence, RI)--The Rhode Island Blood Center says coronavirus fears are keeping healthy donors away and that it has an urgent need for blood and platelet donors.The blood center says half of its donations come from blood drives that are hosted by schools, organizations, and businesses, and that as these groups take precautions in response to the virus outbreak, several blood drives have been canceled this month.The RIBC says it is seeking to double the blood reserves it has now so it can prevent shortages if coronavirus cancellations continue.Donors can give at six centers throughout the state.
