American Charedim are battling a serious mumps outbreak that has been traced to the UK.
The Centre for Disease Control (CDC), a US government health agency, says it is the worst mumps outbreak in the country since 2006. At least four children have been hospitalised.
The virus was brought to America by a New York boy, who caught mumps while holidaying in the UK last summer.
At the time, the UK had 4,000 confirmed cases.
