New Hampshire health officials say norovirus was a contributing cause of the death of a person who had attended a function at a restaurant where a group of guests became sick.
Eighteen people who became ill had attended the private function Nov. 24 at the Puritan Backroom conference center in Manchester.
The person who later died was an adult from Hillsborough County. The state medical examiner's office completed its final report Tuesday.
