Contagious Illness in Schools

Students may be exposed to a variety of communicable diseases and illnesses during their school years. 

Below is a table showing common diseases and symptoms that often make their way into schools. Please read whether the student can continue to attend school, if you need to report the case to the NWHU. Notify NWHU when absenteeism rates appear relatively high (this will help with early detection and management of infectious diseases). 

Please call us any time if you need guidance on infection prevention and control measures.
