A concerning surge in measles cases in South Carolina is putting the U.S.'s measles elimination status at risk. This is a serious situation, as losing this status would be a significant setback for public health. Let's dive into the details.
South Carolina is currently grappling with a significant measles outbreak. The state's health department reported 20 new cases in a single week, bringing the total for this year to 179. To put this in perspective, that's more cases than the entire U.S. saw in six of the last ten years.
Nationally, the U.S. has recorded over 2,000 measles cases this year. According to the Centers for Disease Control and Prevention (CDC), a staggering 93% of these cases are among individuals who are either unvaccinated or whose vaccination status is unknown. This is the highest number of cases since measles was declared eliminated in the U.S. 25 years ago.
Measles is considered eliminated in a country when there's no continuous spread for a full year. The U.S. is quickly approaching this deadline, as sustained transmission has been ongoing since around January 20th. Unless the situation dramatically improves in the next few weeks, the U.S. could lose its elimination status, similar to what happened in Canada last November.
Dr. Linda Bell, South Carolina's state epidemiologist, has stated that measles transmission is ongoing in households, schools, and churches. As a result, 287 people are currently under quarantine to help curb the spread.
The majority of South Carolina's cases this year are linked to an outbreak in Spartanburg County, with most cases occurring in unvaccinated individuals, particularly children between 5 and 17 years old. Dr. Bell also noted that holiday gatherings and travel likely contributed to the spread. Sadly, at least 3 people in South Carolina have been hospitalized due to measles complications.
But here's where it gets controversial... The rise in measles cases is largely attributed to a decrease in childhood vaccination rates and a rise in vaccine exemptions. For the 2024-25 school year, less than 93% of kindergartners received the required two doses of the MMR (measles, mumps, and rubella) vaccine, compared to 95% in the 2019-2020 school year. Health experts agree that a vaccination rate of at least 95% is needed to effectively control the virus's spread.
Earlier this year, a large measles outbreak in West Texas contributed significantly to the national total, with around 760 cases recorded between January and August. This outbreak was concentrated in Gaines County, where only 77% of kindergartners were vaccinated for measles during the 2024-25 school year. Some families in the area opted for unproven remedies instead of vaccination.
Tragically, two unvaccinated, school-aged children in Lubbock, Texas, died from measles, as did an unvaccinated adult in New Mexico. Before this year, the U.S. hadn't seen a measles death in about a decade.
In addition to South Carolina, measles cases are also present in Arizona and Utah. There's also a recent case in Washoe County, Nevada, and health officials have warned of potential measles exposures at several major airports.
And this is the part most people miss... Public health experts have raised concerns about the federal messaging on vaccines since Health and Human Services Secretary Robert F. Kennedy Jr. took office. While Kennedy has encouraged people to get the MMR shot, he has also framed vaccination as a personal choice and emphasized unproven treatments, while falsely claiming that immunity from measles vaccines wanes quickly.
Common measles symptoms include a blotchy rash, high fever, cough, runny nose, and pink or watery eyes. Severe cases can lead to pneumonia or brain swelling. The virus can remain airborne for up to two hours after an infected person leaves a space. Without immunity from vaccination or prior infection, approximately 9 out of 10 people exposed to measles will contract it.
State and county health departments continue to stress that vaccines are the most effective way to prevent measles. Two doses of the MMR vaccine are 97% effective and usually provide lifelong protection.
