More than three hundred children and staff at a primary school in Cardiff have been screened for Hepatitis after two pupils were diagnosed with the virus.
Health officials say no new cases have been identified at Meadowlane Primary in St Mellons.
Staff and pupils at the school have been screened for the infection by staff from the Cardiff and Vale University Health Board.
Those in close contact with the two pupils in the school and their families have been offered a vaccination.
Public Health Wales said: “The school has been extremely supportive and we continue to work closely with Cardiff council environmental health officers to investigate the cases and to offer advice to parents, school staff and pupils.
“There is no wider risk outside the school community.
“Hepatitis A is usually a short term infection that has very unpleasant symptoms but is rarely serious.
“Symptoms include flu-like symptoms like tiredness, general aches and pains, headaches and fever, as well as loss of appetite, nausea or vomiting, diarrhoea, abdominal pains, jaundice, very dark urine and itchy skin.
“People are advised to contact their own GP if they have any concerns about their health or their child’s health.”No new cases have been identified but we continue to monitor the situation.”
