Hepatitis A outbreak at North Ridge Elementary in Surrey

Fraser Health is alerting students and staff and offering vaccinations at North Ridge Elementary in Surrey today after several people became ill with hepatitis A.

"We believe transmission may have occurred within the school setting," stated Fraser Health in an alert Sunday evening.

"We want to offer vaccines as soon as possible because, if given in 14 days, the vaccine can prevent the illness from happening at all," said Dr. Helena Swinkels with the Fraser Health Authority.

The health authority is recommending students and staff of North Ridge Elementary be vaccinated against hepatitis A, and offering a clinic at the school Monday from 10 a.m. to 3 p.m. PT.

Hepatitis A is a liver infection caused by a virus, and is spread when a person eats or drinks something that has come into contact with infected stool or vomit.
