March 19 (UPI) -- The number of cases of meningitis in Kent has risen to 27, the United Kingdom Health Security Agency reported.

There are 15 confirmed cases, and 12 suspected cases, meaning health professionals suspect the illness based on symptoms.

Two people have died since the outbreak began: One high school student and a college student at the University of Kent.

"What is particularly remarkable about this case, and unexpected about this case, is the large number of cases all originating from what seems to be a single event," Robin May, chief scientific officer at the UKHSA, told The Guardian.
