MANCHESTER, N.H. (AP) — Eighteen people were sickened with a gastrointestinal illness after attending a private function last month at a restaurant co-owned by a Democratic congressman that’s popular with presidential candidates, state health officials said Friday.

People who became ill with norovirus attended the private function Nov. 24 at the Puritan Backroom in Manchester, the state Department of Health and Human Services said. One person later died but it was unclear if the death was related to the norovirus outbreak, the department said.
