Hepatitis A outbreak confirmed at two Leeds schools
People living in an area of Leeds are being vaccinated against hepatitis A after several school pupils contracted the disease.
Public Health England (PHE) said there had been about 20 cases in the LS9 area, including some at Brownhill Academy and Richmond Hill Primary.
Jabs are being offered at the schools and at drop-in clinics pupils, staff and local residents.
PHE said symptoms of the virus include a fever, vomiting and diarrhoea.
It is relatively uncommon in the UK.
PHE said it was working with Leeds City Council and the NHS to offer the vaccinations.
Mike Gent, a consultant in communicable disease control at PHE, said: "We have targeted the people living in the area where the cases have been to offer them vaccination as a preventative measure to help make sure the infection does not spread further into the community.
"This has included inviting people living closest to where the cases have been to drop-in clinics in the area for vaccinations and we will be vaccinating the staff and pupils in two local schools where there have been cases confirmed among the pupils."
