Parents are being urged to download a new poster on common childhood illnesses and stick it on their fridge.
Local NHS experts have joined forces with Essex County Council and Billericay Community Trust to produce an at-a-glance guide to 17 childhood illnesses including Chicken Pox, Glandular Fever, Ringworm and Tonsillitis.
The poster highlights key symptoms of common illnesses which are traffic light colour coded to indicate whether children should go to school or stay at home.
Illnesses in the green category – for example colds and conjunctivitis - are those where children should continue to go to school.
Amber is when an illness could be catching and there are some restrictions on school attendance.
Children should not go to school and should see a GP if the illness falls into the red category. Red category illnesses are German measles. Impetigo, Measles and Whooping Cough.
The poster also advises parents on where they should first seek treatment, either from their local pharmacist or their GP.
There is guidance on when to consult a GP if symptoms persist and advice on when it should be safe for a child to return to school if they have a particular illness.
