A mumps outbreak among Frum Jews in New York and New Jersey has now surpassed 1,500 cases and shows no sign of ending soon, WCBSTV reports.
The outbreak began last summer at a boys camp in the Catskills. Nearly all the cases are in the insular Orthodox Jewish community. Health officials said most had a mumps vaccination, but the shots are not completely effective.
The Centers for Disease Control and Prevention on Thursday said the count has now reached 1,521. Nineteen people have been hospitalized but no deaths have been reported.
Investigators say the outbreak started in August 2009 at a Jewish summer camp in Sullivan County with an 11-year-old boy who brought the disease from England.
It has since spread to Jewish communities in Brooklyn, New Jersey and Orange county.
Mumps spreads through saliva, coughing and sneezing. Common symptoms are flu-like and include swelling of the salivary glands.
