State health officials have been unable to determine the culprit in the late November outbreak of norovirus at the Puritan Backroom banquet center, which sickened 20 and factored into the death of one, according to an eight-page report released Thursday.
Officials said the evidence led to no conclusions about the contagion’s source. Nor could they say whether it was spread through food, person-to-person contact, a contaminated environment or other potential contamination routes.
