Andy Fox, consultant in public health for Lincolnshire County Council, said: “Schools continue to take measures to limit the potential spread of the virus and will inform parents of positive cases where necessary.
“However, in some cases, the person testing positive may have already been out of school, meaning there is no impact on other pupils or staff.
“It’s also important to remember that, due to the expansion of testing at home for staff, pupils and parents, positive cases may not be the result of transmission within school.”
