Columbia, SC - February 11th, 2026 - While the initial surge of measles cases in South Carolina appears to be slowing, the virus continues to pose a public health threat as it spreads to a ninth county, Dorchester, health officials confirmed on Tuesday. The South Carolina Department of Health and Environmental Control (DHEC) reports a total of 34 confirmed measles cases since the outbreak began in December, impacting Charleston, Berkeley, Dorchester, Fairfield, Lancaster, Lee, Kershaw, and York counties.

The recent identification of cases in Dorchester County, the first new county impacted in nearly a month, signals a concerning shift in the outbreak's geography, even as the rate of new confirmations appears to be decelerating. This suggests the virus isn't simply contained within the originally affected areas, but is capable of spreading further - potentially indicating undetected transmission chains.

"While we are encouraged by the potential slowing of new cases, the expansion to Dorchester County is a stark reminder that measles remains a serious risk," stated Dr. Emily Carter, State Epidemiologist at DHEC, in a press conference today. "We urge all South Carolinians, particularly those with young children or compromised immune systems, to ensure they are fully vaccinated against measles."

Understanding the Measles Threat

Measles is a highly contagious respiratory disease caused by a virus. It's spread through the air when an infected person coughs or sneezes. The virus can remain airborne for up to two hours, and a single infected person can infect up to 90% of those who are not immune. This high transmissibility is why outbreaks can spread quickly, even in communities with relatively high vaccination rates.

Symptoms typically begin with a high fever, cough, runny nose, and red, watery eyes - often referred to as the "three C's." These are followed by a characteristic rash that starts on the face and spreads throughout the body. While many people recover from measles without serious complications, the disease can lead to pneumonia, encephalitis (inflammation of the brain), and even death, particularly in vulnerable populations.

Vaccination: The Cornerstone of Prevention

The most effective way to protect against measles is vaccination. The measles, mumps, and rubella (MMR) vaccine is highly effective - two doses are approximately 97% effective at preventing measles. The Centers for Disease Control and Prevention (CDC) recommends that children receive their first dose of the MMR vaccine between 12 and 15 months of age, and the second dose between 4 and 6 years of age. Adults born in 1957 or later who have not had measles or been vaccinated should also receive the MMR vaccine.

"Vaccination isn't just about protecting individuals; it's about protecting our community," Dr. Carter emphasized. "When enough people are vaccinated, we create 'herd immunity,' which helps to protect those who cannot be vaccinated, such as infants too young to receive the vaccine or individuals with certain medical conditions."

Current DHEC Response and Recommendations

DHEC is actively investigating the outbreak and working with local health departments to identify and isolate cases, trace contacts, and provide vaccination opportunities. They are also reinforcing their public health messaging about the importance of vaccination and early symptom recognition.

Individuals experiencing symptoms consistent with measles should immediately contact their healthcare provider before seeking medical attention. This allows healthcare providers to take precautions to prevent the spread of the virus in waiting rooms and other areas. DHEC also strongly advises symptomatic individuals to stay home and avoid contact with others to prevent further transmission.

Furthermore, DHEC is working with school districts and childcare facilities to ensure high vaccination rates among students and staff. They are also monitoring vaccination coverage data to identify areas where vaccination rates are low and focusing resources on increasing access to vaccines.

The situation remains fluid, and DHEC will continue to provide updates as the outbreak evolves.

The expansion to Dorchester County underscores the ongoing need for vigilance and proactive measures to combat the spread of measles and safeguard public health in South Carolina.
