South Carolina's Measles Outbreak Surpasses Texas as U.S. Nears Loss of Elimination Status
Predominantly unvaccinated children and teens have been infected, with about two dozen schools under quarantine and rising expected hospitalizations and deaths.
It took South Carolina 16 weeks to pass what Texas took seven months to reach
Mark
Why does 16 weeks versus seven months matter so much?
Mimi
Because it shows speed. Texas took seven months to reach its total, and South Carolina passed it in about four. Dr. Bell said it's disconcerting to think about where this ends.
Mark
Is the loss of elimination status already decided?
Luke
No. PAHO plans to review it this spring. Daskalakis says it's already lost, but that's his assessment, not a ruling.
Mimi
And there are two routes to losing it: proof of one continuous chain from Texas, or failure to show the U.S. can stop spread quickly and consistently.
Mark
What did the CDC's Ralph Abraham say about it?
Mimi
Asked if it was significant, he said "Not really," and framed vaccination as a matter of personal and religious freedom.
Luke
Worth noting he also said the administration supports the vaccine. The disagreement is about emphasis and what to do about communities that decline.
Mark
What does it cost beyond the illness itself?
Mimi
Moss cites estimates of $43,000 per case, and over $1 million for outbreaks of 50 or more.
Luke
Those are estimates, and the source doesn't say how they were built. The 847 count is confirmed, but hospitalizations and deaths in South Carolina aren't given here, and Burch's prediction of growth is a clinician's expectation, not a forecast.
El Pulso
- South Carolina's measles count has reached 847 cases, outrunning Texas in just 16 weeks, and the daily tally is still climbing.
- About two dozen schools have sent students into quarantine as infections spread through classrooms and campuses at Clemson and Anderson.
- The virus has leapt across state lines into North Carolina and Washington, where health officials are tracing chains tied to a single visiting family.
- Public health leaders are racing to contain the outbreak while federal officials downplay the loss of elimination status, leaving PAHO's spring review as the next decisive moment.
In a South Carolina that has already seen 847 measles cases since October, a disease once thought largely behind it has found its way back into homes, schools, and children's bodies with unsettling speed. The state's count now surpasses the Texas outbreak that began a year earlier, reached in roughly half the time, and the infections cluster among unvaccinated young people whose families made choices that ripple outward across state lines. Meanwhile the nation itself stands at the edge of losing a hard-won standing it held for a quarter century, a reminder that the protections built over generations depend on the steady consent of ordinary communities. What will be decided in the coming spring review is not only a technical question but a measure of how much collective memory of measles remains.
South Carolina has now confirmed 847 measles cases since October, a total that has pushed its outbreak past the one that swept Texas over the past year. The state reported 58 new cases in just a few days, and the state epidemiologist, Dr. Linda Bell, called the speed of the milestone deeply troubling. Texas needed seven months to reach its count; South Carolina covered the same ground in sixteen weeks.
Most of the sick are unvaccinated children and teenagers. About two dozen schools have quarantined students, and universities including Clemson and Anderson have reported cases. The virus has already traveled: North Carolina has confirmed linked infections, and in Washington state, officials traced six cases in unvaccinated children to a family that had visited South Carolina. In Spartanburg County, school vaccination rates sit at 90 percent, short of the 95 percent needed to keep outbreaks from taking hold.
The country is also at risk of losing its measles elimination status, a designation held since PAHO declared the disease eliminated in 2000. Whether the outbreaks form one unbroken chain beginning in Texas will be weighed by an international commission this spring. Some experts, including former CDC official Dr. Demetre Daskalakis, believe the status is already lost. The administration has signaled that it does not consider the loss especially significant, while epidemiologists point to declining vaccination and misinformation as the forces driving the resurgence. The cost is measured not only in illness and possible deaths but in resources diverted from other public health work.
South Carolina has now confirmed 847 measles cases since the first was reported in October, a count that puts its outbreak ahead of the one that began in Texas a little over a year ago. On Friday, the state reported 58 new cases since Tuesday, and there is little sign the pace is easing.
The speed is what struck the state epidemiologist, Dr. Linda Bell. Texas took seven months to reach its total; South Carolina passed it in 16 weeks. At a Wednesday press briefing she called it a milestone reached in a short time, "very unfortunately," and said it was disconcerting to consider where the final trajectory might lead.
Most of the cases, as in Texas, are in unvaccinated children and teenagers. About two dozen schools have quarantined students. Clemson University and Anderson University have both recently reported cases. The virus has also crossed state lines: North Carolina has confirmed several cases tied to the South Carolina outbreak, and in Washington state, Snohomish County officials told NPR they have linked six cases in unvaccinated children to a family visiting from South Carolina. In Spartanburg County, the schoolwide vaccination rate for required immunizations is 90%, below the 95% or higher considered ideal for keeping outbreaks from taking hold.
Dr. Anna-Kathryn Burch, a pediatric infectious disease specialist with Prisma Health in Columbia, said it breaks her heart to see her state in this position. She was born and raised there, she said, and expects the numbers to keep growing over the next several months.
The outbreak lands as the United States is already at risk of losing its measles elimination status, a technical designation given to countries that go a year without a continuous chain of transmission. For the U.S., that clock started in January 2025 with the Texas outbreak. The Pan American Health Organization (PAHO) set up a verification commission that grants and revokes the status. It must review epidemiological data, genomic analyses and surveillance reports to decide whether the current outbreaks form one chain beginning in Texas. PAHO has said it plans to review the U.S. status this spring.
Even if the outbreaks prove separate, said Dr. Demetre Daskalakis, an infectious disease specialist and former top CDC official, the U.S. could lose the status if it cannot show it can stop measles spread quickly and consistently. He said it is failing at that. "I'm going to say that elimination is already lost," he said at a press briefing this month.
The administration has taken a different tone. Asked on a press call this month whether losing elimination status mattered, Dr. Ralph Abraham, the CDC's principal deputy director, answered, "Not really." He said it would not change how the administration approaches measles, which he said it supports vaccinating against. He added that the president and Secretary Kennedy often talk about religious, health and personal freedom, and that communities choosing "a somewhat of a different route" should be respected. Epidemiologists respond that declining vaccination is what drives these outbreaks, and Daskalakis points to misinformation that erodes trust in vaccines.
Caitlin Rivers, an epidemiologist at the Johns Hopkins Bloomberg School of Public Health, said the loss would be more than symbolic. The country held elimination for 25 years, after PAHO declared measles eliminated in 2000, and she described its slipping away as a sign of a cycle of panic and neglect in which people have forgotten what widespread measles looks like. Dr. William Moss of Johns Hopkins' International Vaccine Access Center expects more hospitalizations and deaths, and cites estimates of about $43,000 per case on average, with outbreaks of 50 or more cases costing well over $1 million. Those resources, he noted, are pulled from other public health work.
Elimination is not eradication: the virus remains endemic in many parts of the world, and imported cases reach the U.S. every year. Measles spreads with exceptional ease. An infected person can be contagious from four days before the rash appears until four days after, and infectious particles can hang in the air for up to two hours. One person can infect up to 18 unvaccinated others. Two doses of the MMR vaccine are 97% effective. PAHO's spring review is the next formal marker to watch.
