Measles Outbreaks Prompt School Quarantines Across the U.S.
Hundreds of students across the United States have been quarantined as measles outbreaks spread through several states, forcing schools to confront the growing impact of declining vaccination rates.
In South Carolina, health officials ordered 153 unvaccinated students to remain home for at least 21 days after potential exposure to the virus, according to NBC News. A similar situation is unfolding in Minnesota, where 118 students in the Minneapolis–St. Paul area are under quarantine as the state works to contain its own outbreak. For many families, this means nearly a month of remote learning while parents are urged to watch for early symptoms such as fever and rash.
Since late August, the Centers for Disease Control and Prevention (CDC) has reported an average of 27 new measles cases per week. The most recent outbreak has emerged in Ohio, CNN reports. Until this year, the U.S. had seen just ten large outbreaks since measles was declared eliminated in 2000. The CDC defines a “large outbreak” as one involving more than 50 related cases.
Public health experts warn that these incidents could become more frequent. Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, said communities should expect additional quarantines as measles spreads in areas with low vaccination coverage.
In South Carolina, state health officials confirmed ongoing, unrecognized community transmission, with recent cases identified in schools in Greenville and Spartanburg counties. Vaccination rates in these regions hover around 90%, below the 95% level needed to prevent outbreaks.
“When you have multiple cases happening, particularly with those numbers, it’s only possible because you have susceptible individuals,” explained Dr. Scott Harris, president of the Association of State and Territorial Health Officials.
Health authorities continue to urge families to stay up to date on immunizations to prevent further school closures and community spread.
