All pupils and staff in Reception, Nursery, Year 5 and Year 3 at Manor Primary School in Bilston have been told to self-isolate after positive cases of coronavirus.
A child and staff member at the school have tested positive so all pupils and staff in Reception and the Nursery are self-isolating until November 30.
And staff and pupils in Year 5 are self-isolating until November 23 as the pupil who tested positive was not in school last week.
And a child in Year 3 has tested positive so all other pupils will be self-isolating until November 30.
Headteacher Julie Mills said: "This morning school received notification from parents and staff about three positive Covid cases. As a result school contacted Public Health England and acted swiftly on their advice to close a number of year group bubbles.
"School continue to monitor the situation to ensure the health, safety and well-being of our whole school community is of the highest priority. We would like to thank our parents and carers for their patience and support at this time."
