If you are not sure if the ILI activity in your school needs to be reported, please contact the Disease Reporting Line at (808) 586-4586. ILI activity in schools is immediately reportable, so please do not hesitate to call. HDOH personnel will assist you in determining how to proceed with your particular situation.

During the outbreak, HDOH personnel will be able to assist you in preventing further spread of infection in your school. We will send you free kits to swab your students for influenza and other respiratory virus testing. You may be able to work closely with your public health nurse or Disease Investigation Branch personnel to collect specimens for testing at the Hawaii State Laboratories Division.

Once the specimens have been tested, we will know if your school has an influenza outbreak or an outbreak of another respiratory virus. In the event of a confirmed respiratory virus (including influenza) outbreak, HDOH personnel will provide you with materials you may need to encourage students to stay at home and practice good hygiene. This will prevent the outbreak from spreading further.
