The measles outbreak in South Carolina has spiraled out of control, with the total number of cases reaching 434 - a dramatic increase from just 99 cases reported a week ago. Health officials are sounding the alarm, urging everyone to get vaccinated against the highly contagious virus as they struggle to trace new exposures, including a recent incident at the South Carolina State Museum.

Why it matters

Measles is a highly contagious disease that can lead to serious complications, especially in unvaccinated individuals. The rapid spread of the outbreak in South Carolina highlights the importance of vaccination efforts to protect public health and prevent further escalation of the crisis.

The details

The outbreak, which began in October, has now doubled in size in just one week, with 124 new cases reported since Friday. With 409 people currently in quarantine, the situation is dire. The health department is taking action by activating its mobile health unit to offer free measles-mumps-rubella (MMR) and flu vaccinations in the Spartanburg area, the epicenter of the outbreak. However, vaccination efforts have met with little success since October, and the department is warning that they are losing the ability to trace cases, with new public exposures occurring, such as a contagious measles case at the South Carolina State Museum last Friday.

  • The outbreak began in October 2025.
  • On January 6th, there were 26 new cases reported.
  • On April 5th, there were 99 new cases reported.
  • On April 7th, there were 124 new cases reported, bringing the total to 434 cases.
