Children in reception, year one and year six have been back in classrooms for at least a month – but how can parents tell the differences between Covid-19 and other winter bugs?
With children back at school they will once again be mixing with their school friends.
Many children returned to school on June 1 and others have been gradually walking back through the school gates.
It's important parents remain vigilant and look out for the key symptoms of Covid-19.
Scientists are still trying to understand the new illness, but research so far suggests that there are fewer cases of the virus reported in children.
A study in the New England Journal of Medicine also said that "children might be less likely to become infected or, if infected, may show milder symptoms" than adults.
Symptoms may appear similar to other respiratory illnesses, such as the flu and the common cold, but this new strain is said to be more likely to trigger cough and fever, researchers said.
