Measles flare‑ups return
Measles activity is rising in parts of the U.S., with Utah now the epicentre of current outbreaks and cases spreading to unvaccinated people across the state. (cidrap.umn.edu) Public‑health officials are also flagging vaccination gaps in places like British Columbia and recommending accelerated shots in outbreak counties in Michigan, even as Snohomish County says its local outbreak is over.

Measles spreads so easily that the virus can hang in the air for up to 2 hours after an infected person leaves a room, and the Centers for Disease Control and Prevention says up to 9 out of 10 unprotected people nearby can catch it. (cdc.gov(cdc.gov)) (utah.gov(epi.utah.gov)) It usually starts like a bad cold, with fever, cough, runny nose, and red eyes, and the rash often comes later, 7 to 14 days after infection. That delay is one reason outbreaks can move before families realize what they are dealing with. (cdc.gov(cdc.gov)) (utah.gov(epi.utah.gov)) The United States is already deep into a heavy measles year. The Centers for Disease Control and Prevention said 1,671 confirmed cases had been reported in 2026 as of its April 3 update, and 94 percent were tied to outbreaks. (cdc.gov(cdc.gov)) Utah is now carrying the biggest active cluster. Utah’s measles dashboard shows 583 cases in the 2025–2026 outbreak period, with 249 in Southwest Utah, 93 in Utah County, 62 in Salt Lake County, and 59 in the TriCounty area. (utah.gov(files.epi.utah.gov)) Utah health officials are posting exposure sites across the state because people with measles kept turning up in everyday places, including clinic waiting rooms. The state says those waiting-room exposures are a real risk for babies who are too young to be fully protected. (utah.gov(epi.utah.gov)) (utah.gov(epi.utah.gov)) Michigan is reacting before more chains of spread take hold. On April 2, the Michigan Department of Health and Human Services told families in 7 counties that infants ages 6 to 11 months should get an early measles, mumps, and rubella shot if they live in those counties or are traveling into Washtenaw or Monroe counties. (michigan.gov(michigan.gov)) Those 7 counties are Washtenaw, Monroe, Wayne, Oakland, Jackson, Livingston, and Lenawee. The state said the advice changed because of possible ongoing community transmission, which means the virus may be moving person to person without every link being traced. (michigan.gov(michigan.gov)) (michigan.gov(michigan.gov)) Washington state just showed the other path an outbreak can take. Snohomish County said on April 7 that its outbreak was over after 14 cases, with February 21 marked as the last day one case was infectious and April 4 counted as the end of the outbreak window. (snohd.org(snohd.org)) North of the border, British Columbia officials are warning that the same openings exist there. The province says measles cases have risen sharply across British Columbia and Canada, and the Public Health Agency of Canada says 650 cases had been reported nationwide in 2026 as of March 21. (gov.bc.ca(www2.gov.bc.ca)) (canada.ca(health-infobase.canada.ca)) The weak spot is vaccination coverage. Public Health Agency of Canada guidance says measles usually needs about 95 percent coverage to keep outbreaks from finding enough unprotected people, and British Columbia’s disease center says measles is resurging as immunization rates decline. (canada.ca(canada.ca)) (bccdc.ca(bccdc.ca)) The protection itself is simple. The Centers for Disease Control and Prevention says children should get 2 doses of the measles, mumps, and rubella vaccine, first at 12 to 15 months and again at 4 to 6 years, with special early doses used in higher-risk situations like travel or active spread.
