The outbreak began on October 2, 2025, and was seeded in a number of private elementary and middle schools where the student body had low vaccination rates. There have been no new cases recorded since March 17.
If no new cases are reported, the last day of the outbreak will be April 26.
“There currently are no people in quarantine or isolation. If no new cases are reported, the last day of the outbreak will be April 26,” officials said. “A period of 42 days with no new cases is required to declare an end to a measles outbreak. This is double the number of days for an incubation period (21 days) and a clear indicator of a broken transmission chain.”
Among the 997 cases, 639 are aged 5 to 17, and 264 are under the age of 6. Among those infected, 932 were unvaccinated, 20 were partially vaccinated, 26 were fully vaccinated, and 19 had unknown status.
In similar news, Snohomish County, Washington, this week announced an end to a measles outbreak that began on January 15. A total of 14 measles cases were recorded during the outbreak, and the last reported case was February 17.
So far this year, Washington State has had 33 measles cases.
Utah reports 24 new cases
With the outbreak in South Carolina seemingly under control, Utah now has the most active outbreak in the country, with officials recording 24 new cases in the last five days, raising the outbreak case count to 583.
Of those cases, 386 have been recorded this year, with 121 in the last three weeks. The Southwest Health Area has the most cases with 249, followed by Utah County with 93 cases, and Salt Lake County with 62 cases.
So far 47 people have been hospitalized during this outbreak, officials said.
100 children dead in Bangladesh
In international measles news, a growing measles outbreak in Bangladesh has hit a grim milestone, with more than 100 children dead. Officials say a drop in newborn vaccination in the South Asian nation is fueling the activity.
The outbreak began on March 15. So far, more than 900 cases have been recorded in three weeks, with one-third of case-patients 9 months of age or under. Country officials said a massive vaccination campaign targeting infants will begin this week.
