St. Croix County HHS briefs board on measles preparedness as national cases rise

St. Croix County public‑health staff updated the Health and Human Services Board on April 16 about national measles activity and local preparedness, urging residents to check immunization records and use local vaccination clinics.

"We don't, at this point in time, have any measles cases in Wisconsin," said Heather Prigge, the county public‑health nurse, citing CDC data compiled through April 3. She told the board the presenter slide showed roughly 670–712 confirmed cases nationally, cases reported in 25 jurisdictions, seven outbreaks and three deaths at that snapshot in time.

Prigge reviewed Wisconsin reporting categories, local surveillance and case‑investigation steps: local category‑1 and category‑2 illnesses prompt follow‑up, outbreaks (three or more cases in defined settings) require mandatory facility reporting in long‑term care, and public‑health staff use the Wisconsin electronic disease surveillance system to coordinate with providers and the state. In St. Croix County the nursing team had followed up on 192 diseases so far that year, with 21 category‑1 and 171 category‑2 cases; pertussis was the largest category‑1 illness noted.

Prigge explained measles' infectious period (beginning up to four days before rash onset and extending four days after) and recommended that people who are unsure about immunity consult records or get a booster. Post‑exposure prophylaxis (MMR vaccine within 72 hours) and quarantine (up to 21 days for the general public in some exposures) were described as part of the public‑health toolkit. Prigge said the county publicly offers weekly vaccination clinics and that MMR is available through county providers and most pharmacies.

During public comment, a resident raised concerns about vaccine safety, aluminum and suggested links to autism. Dr. Finley responded, noting the initial study that proposed an MMR‑autism link was a small case series that has been discredited and the physician who published it lost medical privileges; Dr. Finley said, "what we know about MMR vaccination is that it is safe. It is not causing autism." The board acknowledged differing community views while recommending vigilance and preparation for exposure response.

Public‑health staff said they will bolster communications, publish a measles page on the county website, and coordinate with schools, long‑term‑care facilities and providers. No local measles cases were reported at the time of the briefing.
