Understanding the Threat

Measles is a highly contagious respiratory disease that can spread rapidly among unvaccinated populations. According to epidemiological experts, a single case can lead to up to 18 new infections in susceptible individuals .

Strengthening Public Health Preparedness

The Autonomous University of Bucaramanga (UNAB), in collaboration with Foscal and other health institutions, is actively working to bolster the region’s preparedness for public health events. This collaborative approach mirrors successful strategies previously employed to address health threats like yellow fever, as highlighted by Juan José Rey Serrano, dean of the Faculty of Health Sciences at UNAB.

Vaccination: The Primary Defense

Health authorities emphasize that vaccination remains the most effective tool for preventing measles and its complications. Edgar Augusto Bernal García, an infectious disease doctor and professor at UNAB, stated that the vaccine has a proven track record of saving lives globally.

Current Response Measures

The detected cases in Santander are believed to be linked to imported infections. In response, authorities are reinforcing measures such as contact tracing, laboratory confirmation, and the implementation of epidemiological fences to limit further spread. Public health officials are urging residents to review their vaccination status, particularly those planning travel or attending large gatherings.
