Central America Faces a Resurgent Measles Threat: What’s Driving the Comeback?
A worrying trend is emerging across Central America: a resurgence of measles. Recent reports from Mexico, Guatemala, Honduras, and El Salvador indicate a rise in cases, prompting health authorities to issue alerts and scramble to contain potential outbreaks. This isn’t just a regional issue; it reflects a global decline in measles vaccination rates and highlights vulnerabilities in public health infrastructure.
The Numbers Paint a Stark Picture
Mexico is currently at the epicenter of the outbreak. As of January 23rd, 2026, the country has recorded 987 measles cases this year, adding to a total of 7,417 cases since 2025, tragically resulting in 26 deaths. Jalisco, Chiapas, and Sinaloa are the hardest-hit states, with active outbreaks in 32 regions and transmission occurring in 265 municipalities. Guatemala has confirmed 82 cases, a significant portion affecting children under 14. Honduras reports four suspected cases, a concerning development given the country hadn’t seen an indigenous case since 1997. Even El Salvador, which had maintained a measles-free status since 1996, recently confirmed an imported case from Guatemala.
Did you know? Measles is one of the most contagious diseases known to humankind. It’s estimated that one infected person can spread the virus to 90% of those who are not immune.
Why Now? Unpacking the Root Causes
The resurgence isn’t accidental. Experts point to a confluence of factors. Declining vaccination rates are a primary driver. Vaccine hesitancy, fueled by misinformation and distrust in public health institutions, is a growing problem globally. Access to healthcare remains unequal, particularly in rural and marginalized communities. This means even when vaccines are available, reaching those who need them most is a challenge. The COVID-19 pandemic also disrupted routine immunization programs, creating a backlog of unvaccinated individuals.
The World Health Organization (WHO) has repeatedly warned about the dangers of falling vaccination coverage. A 2024 WHO report indicated that over 22 million infants missed their first dose of the measles vaccine in 2023, the highest number since 2008. This global trend is directly reflected in the outbreaks we’re now seeing in Central America.
The Risks: Beyond a Childhood Illness
Measles is far more dangerous than many realize. While often perceived as a mild childhood illness, it can lead to severe complications, including pneumonia, encephalitis (brain swelling), and even death. The WHO estimates that measles remains a leading cause of death among children worldwide. Complications are particularly severe in malnourished children and those with weakened immune systems. Even in developed countries, outbreaks can overwhelm healthcare systems.
Pro Tip: If you or your child experience symptoms of measles – fever, cough, runny nose, red, watery eyes, and a rash – seek medical attention immediately. Isolate yourself to prevent further spread.
Future Trends and Potential Scenarios
Several trends suggest the situation could worsen before it improves. The upcoming school year poses a significant risk. Schools are breeding grounds for infectious diseases, and increased contact among children will likely accelerate transmission. Climate change could also play a role, as extreme weather events disrupt healthcare access and displace populations, increasing vulnerability to outbreaks.
We can anticipate increased investment in vaccination campaigns, but these efforts will need to be targeted and culturally sensitive to address vaccine hesitancy. Strengthening public health infrastructure, particularly in underserved communities, is crucial. This includes improving surveillance systems to detect outbreaks early, ensuring adequate vaccine supply, and training healthcare workers. Digital health solutions, such as mobile vaccination clinics and telemedicine, could also help reach remote populations.
The Role of International Collaboration
Containing the measles resurgence requires a coordinated international response. Organizations like the WHO, UNICEF, and the Pan American Health Organization (PAHO) are working with governments in Central America to provide technical assistance and financial support. Sharing data and best practices is essential. Cross-border collaboration is particularly important, as measles can easily spread across national boundaries.
FAQ: Measles – Your Questions Answered
- Is measles preventable? Yes, measles is highly preventable through vaccination. Two doses of the measles vaccine are highly effective.
- How is measles spread? Measles spreads through the air when an infected person coughs or sneezes.
- What are the symptoms of measles? Symptoms include fever, cough, runny nose, red eyes, and a rash that spreads from the head to the body.
- Can adults get measles? Yes, adults who were not vaccinated or did not have measles as children are susceptible.
- Is the measles vaccine safe? Yes, the measles vaccine is safe and effective. Serious side effects are rare.

The situation in Central America serves as a stark reminder of the importance of vaccination and the fragility of public health systems. Addressing the root causes of this resurgence requires a sustained commitment to immunization, equitable access to healthcare, and international collaboration. Ignoring this threat will have devastating consequences, particularly for the most vulnerable populations.
