Children with a cough or high temperature
Children with a continuous cough or whose temperature is high (38c) will need to go home and be off school for 7 days.
The DFE says parents should then get their child tested:
When a child, young person or staff member develops symptoms compatible with coronavirus (COVID-19), they should be sent home and advised to self-isolate for 7 days and arrange to have a test to see if they have COVID-19. They can do this by visiting NHS.UK to arrange or contact NHS 119 via telephone if they do not have internet access.
There are undoubted other illnesses that give a cough and a temperature but at the present time
UNLESS THERE IS A NEGATIVE TEST RESULT WE CANNOT ASSUME THAT IT IS NOT COVID19
