Concord health staff report spike in influenza, review norovirus case and outbreak precautions
Loading...
Summary
Town public health staff reported an increase in influenza cases and discussed a reported norovirus case, steps for outbreak response, and outreach to schools and food establishments.
Concord public health staff told the Board of Health on Feb. 12 that influenza activity in town has increased and that the department followed up on a reported norovirus case.
"We do have a increase in influenza right now," the public health nurse reported during the meeting, noting that influenza cases reported to the town rose compared with earlier counts. The nurse gave the numbers included in the department report showing 41 reported COVID-19 cases in November (and 4 influenza cases) and 23 reported COVID-19 cases in January and 72 reported influenza cases for the same month — figures the nurse said represent only those who sought testing and were reported.
The nurse explained that norovirus is reportable and that the department had one laboratory-confirmed norovirus case in January. Because norovirus testing is uncommon and many cases are self-limiting, staff said, detection and traceback are often difficult. "We had 1 case that tested positive," the public health nurse said, describing follow-up the department conducted with the patient and noting that stool testing is not commonly done unless symptoms persist.
Board members asked about transmission and precautions in shared community settings. Staff advised standard infection-control measures — handwashing, staying home when sick, and, for food establishments and hospitals, having a written norovirus cleanup policy and a response kit per the food code. The nurse said Concord continues to distribute updated guidance and flyers, and that school nurses had received winter-illness tips and outreach materials.
Why it matters: The town’s increase in influenza — as reported by the public health nurse — indicates higher seasonal activity and potential strain on health services and vulnerable residents. Norovirus poses a separate but immediate concern for congregate settings, food service operations and schools.
Staff told the board they will continue routine surveillance, encourage testing when appropriate, promote hand hygiene, and work with restaurants and institutions to ensure they have norovirus cleanup policies and the required equipment. The department also continues to distribute free COVID-19 tests at the library and the Council on Aging.
No formal vote or action was taken; the discussion was an informational report from public-health staff.
