Quick Summary#

A measles outbreak in South Carolina that began in October continues to expand rapidly. State health officials reported on Friday that 99 new cases were identified in just the last three days, bringing the total number of cases in the outbreak to 310.

Currently, 200 people are in quarantine and nine are in isolation. The outbreak is expanding so quickly that health officials are struggling to trace cases and identify people at risk due to the high number of exposure sites. Dr. Linda Bell, state epidemiologist, noted that an increasing number of public exposure sites are being identified, likely exposing hundreds more people who may not be aware they need to quarantine if they are not immune. Officials warn that one measles case can result in up to 20 new infections among unvaccinated contacts.

Outbreak Statistics and Current Status#

The South Carolina health department provided an update on the measles situation Friday, revealing a significant spike in infections. Since Tuesday, 99 new cases have been identified.

This brings the cumulative total for the outbreak, which started in October, to 310 cases. The rapid increase in numbers highlights the ongoing nature of the health crisis.

Containment efforts are currently active. There are 200 individuals currently in quarantine and nine people in isolation.

"An increasing number of public exposure sites are being identified with likely hundreds more people exposed who are not aware they should be in quarantine if they are not immune to measles."

β€” Dr. Linda Bell, State Epidemiologist

Challenges in Contact Tracing#

Health officials are facing significant hurdles in managing the spread of the virus. The outbreak is expanding so quickly that the South Carolina health department is struggling to trace cases effectively.

The difficulty stems from the sheer volume of exposure sites being identified. Officials are working to identify everyone at risk, but the speed of transmission is outpacing their efforts.

Dr. Linda Bell, state epidemiologist and incident commander for the outbreak, highlighted the scope of the problem. She stated that an increasing number of public exposure sites are being identified.

Risk of Further Transmission#

The South Carolina health department warns that there are likely hundreds more people exposed to the virus who are currently unaware of their risk. Many of these individuals may not be immune to measles and do not know they should be in quarantine.

The potential for further spread remains high. Previous measles transmission studies indicate the virus is highly contagious among vulnerable populations.

According to health officials, one single measles case can result in up to 20 new infections among unvaccinated contacts. This statistic underscores the urgency of the current containment efforts.

"Previous measles transmission studies have shown that one measles case can result in up to 20 new infections among unvaccinated contacts."

β€” Dr. Linda Bell, State Epidemiologist
