"This spike is related to international travel, particularly with people returning to Bolton from India.
The cases are now in the community and it seems to be located around the south and south-west parts of the town.
Interestingly, the cases are very much stacked in those under the age of 25.
There were 721 cases reported yesterday in those aged five to 25.
Part of this is because all the school children are testing twice a week, but it is very much present in that younger age group."
