*Numbers in the reports for Montgomery and Prince George's counties reflect calls to the Maryland Poison Center only. Routing for the nationwide telephone number automatically connects callers from these counties to the National Capital Poison Center in Washington D.C. Some callers reach the Maryland Poison Center by dialing local telephone numbers still in service.
