Influenza-like Illness Weekly Reports

DOH collects information on ILI weekly from hospital emergency departments and long term care facilities, and also collects absenteeism information from schools. In addition, the Department gets weekly reports from select hospitals on the number of patients tested for respiratory syncytial virus – a respiratory infection with symptoms similar to flu -- and the number who test positive. Data on positive RSV samples can help show whether another respiratory illness is influencing rates of ILI.
