A single London borough has had 80 cases of a ‘fast-spreading’ measles outbreak in less than three months.

Measles is a highly contagious disease that notoriously causes a red rash behind the ears or hairline that quickly spreads downward.

At least 235 cases of measles have been confirmed in the UK since January, according to UK Health Security Agency data released today.

Of them, 107 occurred in the past four weeks.
