Gavin investigates the swine flu outbreak
Pupils and staff at a school which is the centre of an outbreak of swine flu are all responding well to treatment, health officials say.
The 50 people, including 45 children, are being treated after the bug was detected at Welford Primary School, in Handsworth, Birmingham.
The school is shut for half term and will be specially cleaned to help kill off the disease.
Experts say most of the cases of the illness were "very mild".
Worldwide, around 13,000 people have caught swine flu, with more than 180 in the UK.
All the people who are sick at Welford Primary are being treated at home with medicine.
The Health Protection Agency are investigating how the disease got into the school in the first place.
