Measles Outbreak: A Growing Threat Across the US

News alerts indicate a concerning surge in measles cases, particularly in South Carolina, with ripple effects being felt across the nation. The situation is escalating rapidly, prompting urgent calls for preventative measures and increased vaccination rates.

South Carolina at the Epicenter

The South Carolina measles outbreak is experiencing an astounding rate of growth. Dr. Johnathon Elkes, an emergency medicine physician at Prisma Health in Greenville, South Carolina, reported over 200 new cases in the last seven to nine days, effectively doubling the case count in just one week. He expressed serious concern, stating, “We feel like we’re really kind of staring over the edge, knowing that this is about to get a lot worse.”

As of Friday, the state’s health department confirmed 558 total cases since the outbreak began last fall, with 124 new diagnoses reported since Tuesday. Eight individuals, including both adults and children, have required hospitalization due to complications from the disease. Experts estimate that approximately 200 people are currently actively infected.

Currently, 531 people are under a 21-day quarantine following exposure to the virus. Health officials caution that the reported numbers are likely an undercount, as not everyone with measles seeks medical attention. Each infected individual has the potential to infect up to 12 others, highlighting the virus’s highly contagious nature.

Vaccination: The Primary Defense

The measles-mumps-rubella (MMR) vaccine remains the most effective defense against the virus. Two doses, typically administered around ages 1 and 4, are 97% effective in preventing measles, according to the Centers for Disease Control and Prevention (CDC). Despite this high efficacy, vaccination rates in some areas are falling short of the 95% needed to achieve herd immunity.

In Spartanburg County, the K-12 vaccination rate for MMR is 90% for the 2024-25 school year, while neighboring Greenville County reports a rate of 90.5%. Unfortunately, uptake of free vaccinations offered by the state health department has been limited, with only 18 people (9 adults and 9 children) receiving shots during a recent mobile health unit deployment.

Community Factors and Vaccine Hesitancy

The outbreak is particularly concentrated within a community in Spartanburg County largely comprised of recent immigrants from Ukraine. Dr. Eliza Varadi, a pediatrician, notes that some families harbor vaccine distrust stemming from experiences under Soviet control. She emphasizes the importance of ongoing education and reassurance regarding vaccine safety.

Expanding Beyond South Carolina

The South Carolina outbreak is not contained within state lines. Cases have been reported in at least three other states:

• Ohio: At least three children have been diagnosed.
• North Carolina: Eight cases have been reported since December, seven linked to South Carolina.
• Washington: Three cases have been confirmed in Snohomish County, linked to a family visiting from South Carolina.

Health officials in Washington state anticipate further diagnoses, suggesting that mild cases may be going unreported. Dr. James Lewis, Snohomish County’s health officer, stated, “I really think there are cases out there in the community right now that are relatively mild, and people are managing at home.”

Urgent Call to Action

Medical professionals are expressing significant concern about the potential for further spread. Dr. Helmut Albrecht, an infectious disease specialist at Prisma Health, warned, “We have right now, the largest outbreak in the U.S., and it’s going to get worse before it gets better.” Individuals who may have been exposed to the virus, particularly those unvaccinated, are urged to seek vaccination immediately. If exposure is identified within 72 hours, vaccination can provide rapid protection and potentially avoid the need for a 21-day quarantine.
