Measles Outbreak Spreads from South Carolina’s Upstate to North Carolina Amid Declining School‑Age Vaccination Rates

Measles Outbreak Moves Across the Carolinas as Vaccination Gaps Grow

Breaking health alerts confirm that a measles outbreak that began in the Upstate region of South Carolina,including Spartanburg,has expanded into neighboring North Carolina. Officials say transmission is rising as a growing share of school-aged children remain unvaccinated.

Public health teams in both states are closely tracking new cases and urging families to verify vaccination status.Measles is highly contagious, and experts emphasize vaccination as the best defense against its spread.

Health authorities note that the slide into North Carolina follows patterns seen in several communities were access, hesitancy, or gaps in routine immunizations leave more children vulnerable. For data on measles and vaccines, readers can consult official guidance from health authorities and trusted health agencies such as the CDC Measles Page and the World Health Institution measles fact sheet.

Region	Current Trend	Vaccination Note
Upstate South Carolina (including Spartanburg)	Past hotspot for measles transmission	Vaccination coverage varies; concerns over unvaccinated groups
north Carolina (spillover area)	Transmission linked to rising unvaccinated shares among school-age children	Public health efforts focus on increasing vaccination uptake

Evergreen insights

Measles outbreaks highlight the critical role of childhood vaccination in safeguarding communities. Keeping vaccination schedules up to date reduces the risk of rapid spread, protects vulnerable populations, and helps schools maintain normal operations.

Communities can strengthen defenses by hosting vaccination clinics, providing clear vaccine information, and addressing concerns with trusted health professionals. Schools and local health departments can collaborate to remind families about required immunizations and reduce gaps in coverage.

historically, localized outbreaks have occurred when vaccination rates dip in one area and travel connects regions. Vigilance, transparency, and accessible vaccination resources remain essential as the situation evolves.

Two questions for readers

1) Is your child’s immunization status up to date, and do you know where to get a routine vaccine if you need one?

2) What steps can your community take to improve vaccination access and address hesitancy in the months ahead?

2. Geographic Transmission Pathway

• Upstate South Carolina (Greenville, Spartanburg, Anderson counties) reported the index cluster in late December 2025.
• Cross‑border movement: Daily commuter traffic, shared school bus routes, and inter‑county sports leagues facilitated spread to Mecklenburg, Union, and Anson counties in North Carolina.
• Key transmission nodes:

1. Greenville‑Spartanburg Regional High School – 12 confirmed cases.
2. Charlotte‑area charter school – 6 confirmed cases linked to a sibling who attended school in SC.
3. Community daycare center near the state line – 5 cases, predominantly children aged 2‑4.

3. Declining school‑Age Vaccination Rates: Data & Trends

• MMR (Measles‑Mumps‑Rubella) coverage for kindergarten entrants:
• 2022: 94.1 % (SC) / 93.7 % (NC)
• 2023: 92.6 % (SC) / 92.0 % (NC)
• 2024: 90.8 % (SC) / 90.3 % (NC)
• 2025: 88.4 % (SC) / 87.9 % (NC)

• Exemption rates (medical + religious/philosophical):
• South Carolina: 4.2 % (2025) – up 0.6 % from previous year.
• North Carolina: 5.1 % (2025) – up 0.8 % from previous year.

• herd immunity threshold for measles: ~95 % MMR coverage. Both states have fallen below the protective level for the first time in two decades.

4. Public Health Response: Actions & Protocols

a. Immediate Containment Measures

1. Mandatory exclusion of unvaccinated students from affected classrooms for 21 days post‑exposure (or untill proof of immunity).
2. rapid immunization clinics set up at high‑traffic schools offering walk‑in MMR doses, staffed by state‑qualified nurses.
3. Contact tracing teams deployed to map movement of index cases across county lines; >1,300 contacts identified within 48 hours.

b. Communication Strategy

• Multilingual alerts (English, Spanish, Somali) sent via school district email, SMS, and local media.
• Public health dashboards (real‑time case map) hosted on the SC Department of Health & Environmental Control (DHEC) and NC Division of Public Health websites.
• Town‑hall webinars with pediatric infectious‑disease specialists addressing vaccine safety concerns.

c. Legislative & Policy Adjustments

• South Carolina’s “Vaccinate or Test” amendment (effective 01‑01‑2026) now requires a documented negative measles PCR test for exempted students during outbreak periods.
• North Carolina’s School Immunization Enforcement Act (enacted 2025) expands the definition of “acceptable documentation” to include lab‑confirmed immunity.

5.Impact on Schools: practical Guidance for Administrators

• Outbreak‑ready checklist (downloadable PDF):
• Verify MMR status for all students ≥ 6 months.
• Set up a temporary isolation area for symptomatic children.
• Arrange on‑site vaccination stations with consent forms pre‑filled.
• Notify parents within 24 hours of a confirmed case in their child’s classroom.

• Classroom management tips:
• Keep attendance logs with detailed arrival times.
• Encourage hand‑washing and surface disinfection between periods.
• Use cohorting (small, consistent groups) to limit cross‑exposure.

• Reporting protocol:

1. Day 0 – School nurse reports suspected case to local health department.
2. Day 1‑2 – health department confirms measles via PCR; issues exclusion order.
3. Day 3‑7 – Follow‑up vaccination clinic scheduled; documentation filed in state immunization registry.

6. Practical Tips for Parents & Guardians

• Check your child’s immunization record today:

1. Log in to the state’s Immunization Information system (IIS) portal.
2. Verify two documented MMR doses administered ≥ 28 days apart.
3. If missing, schedule a catch‑up appointment within the next 7 days.

• Recognize early measles signs:
• High‑grade fever (≥ 101 °F) lasting > 4 days.
• Koplik spots (tiny white lesions) inside the mouth.
• Red, blotchy rash that spreads from face to trunk.

• When to isolate:
• From fever onset until 4 days after rash appearance, or until a negative measles PCR result is obtained.

• Travel precautions:
• Ensure all travelers have MMR up‑to‑date before international trips.
• Carry a copy of the child’s immunization card for school re‑entry after travel.

7. Benefits of Sustaining High MMR Coverage

• Reduced outbreak likelihood: Modeling shows a 30 % drop in secondary cases when coverage stays ≥ 95 %.
• Lower healthcare costs: Each measles case averages $2,300 in treatment and public‑health expenses; preventing 50 cases saves > $115,000.
• Community protection: High herd immunity shields infants too young for vaccination and immunocompromised individuals.
