Washington D.C. – A significant increase in measles cases is prompting urgent warnings from the Pan American Health Association (PAHO). The united Nations agency issued an epidemiological alert on Wednesday, Febuary 3, 2026, calling on nations throughout the Americas to bolster surveillance and vaccination efforts to curb the spread of this highly contagious viral disease.
Rising Case Numbers demand Action
The resurgence of measles, a disease once largely eradicated, is particularly concerning. PAHO reported 1,031 confirmed cases in the first three weeks of 2026 alone, following a total of 14,891 cases confirmed throughout 2025. This sharp increase signals a critical need for immediate and coordinated action from Member States to prevent further outbreaks.
North America at the Epicenter
The most substantial outbreaks are currently unfolding in North America. The United States, Mexico, and Canada are reporting the highest numbers of infections, threatening to reverse decades of progress in Measles elimination. Concerns are growing that elimination status could be revoked in certain regions.
United States: Outbreaks in South Carolina and Texas
In the United States, 2,242 cases were confirmed in 2025 and 171 new cases have already been identified in the first three weeks of 2026. South carolina is grappling with a significant outbreak,totaling 876 cases,with the vast majority – 800 – occurring among unvaccinated individuals. A separate outbreak in texas, between January and August 2025, resulted in 762 cases, tragically leading to the deaths of two unvaccinated children and 99 hospitalizations.
Mexico Faces elimination Status Review
Mexico is experiencing its largest outbreak in decades, with 6,428 cases confirmed in 2025 and an additional 740 in early 2026. This surge has placed Mexico’s Measles elimination status at risk, with PAHO scheduling a review on April 13, 2026.
Canada Loses Elimination Status
Canada already lost its Measles elimination status in November 2025 after experiencing multiple outbreaks since October 2024, with 5,436 cases reported in 2025 and 67 cases in the first three weeks of 2026. Regaining elimination status requires sustained interruption of Measles transmission for more than a year.
Understanding Measles: A Highly Contagious Threat
Measles is an exceptionally contagious airborne virus, capable of infecting nine out of ten unvaccinated individuals exposed to it. While symptoms typically resolve within weeks, the illness can lead to severe complications and even death, particularly in young children.
Potential Complications of Measles
Measles can cause a range of health issues,including ear infections,lung inflammation,pneumonia,and encephalitis—a perilous swelling of the brain that can result in seizures and lasting cognitive impairment.
Vaccination: The Cornerstone of Prevention
the only effective means of preventing Measles and halting its spread is vaccination. The measles, Mumps, and Rubella (MMR) vaccine is highly effective and generally administered in two doses. The Centers for Disease control and Prevention (CDC) recommends the first dose before 15 months of age and the second dose before age six.
Despite its proven safety, vaccination rates have declined in recent years due to misinformation and unfounded concerns. Some public figures,like U.S. Health and Human Services Secretary Robert F Kennedy Jr., have made unsubstantiated claims about the vaccine’s efficacy and safety, contradicting scientific consensus.
MMR Vaccine Safety and Efficacy
Experts at the CDC and the Infectious Diseases Society of America consistently emphasize that the MMR vaccine is safe and far less risky than contracting Measles itself. “Ther have been no deaths shown to be related to the MMR vaccine in healthy people,” states the Infectious Diseases Society of America.
| Country | Cases in 2025 | Cases (jan 1-Feb 21, 2026) |
|---|---|---|
| United States | 2,242 | 171 |
| Mexico | 6,428 | 740 |
| Canada | 5,436 | 67 |
The current situation underscores the critical importance of maintaining high vaccination coverage to protect communities from this preventable disease.
What steps can public health officials take to address vaccine hesitancy and improve vaccination rates? How will the PAHO’s review impact public health strategies in the United States and Mexico?

What is causing the recent surge in measles cases across the Americas?
Rising Measles Cases Across the Americas Threaten Elimination Status, PAHO Urges Vaccine Boost
The Pan American Health association (PAHO) has issued a stark warning: measles is making a hazardous comeback across the Americas, jeopardizing decades of progress towards regional elimination. A surge in cases throughout 2024 and early 2026 is prompting urgent calls for increased vaccination efforts to protect populations and prevent widespread outbreaks. This isn’t just a health concern; it’s a public health emergency demanding immediate attention.
The Current Situation: A Regional overview
For years, the Americas have been a global success story in measles control. Officially declared to have eliminated the disease in 2016,the region had maintained that status through robust vaccination programs. However, declining immunization rates, exacerbated by the COVID-19 pandemic and misinformation campaigns, have created vulnerabilities.
Here’s a breakdown of the current landscape:
* Significant Increase: PAHO reports a considerable rise in confirmed measles cases in 2024, with several countries experiencing outbreaks.This trend has continued into the first month of 2026.
* geographic Distribution: While outbreaks are occurring across the region, certain areas are especially affected. Brazil, Colombia, Peru, and Venezuela have reported the highest numbers of cases.The United States has also seen a concerning uptick, largely linked to imported cases.
* Impact on Elimination Status: The sustained transmission of measles in multiple countries puts the region’s elimination status at serious risk. Re-establishment of endemic transmission could led to a resurgence of the disease and its perhaps severe complications.
* Vulnerable Populations: Children under five years of age are the most vulnerable to measles and its complications, including pneumonia, encephalitis (brain swelling), and even death. Individuals with weakened immune systems are also at higher risk.
Why the Resurgence? Understanding the Contributing Factors
Several interconnected factors are driving the increase in measles cases:
* Vaccination coverage Gaps: The primary driver is declining vaccination coverage. Many countries are falling short of the 95% coverage rate needed to maintain herd immunity – the protection offered when a large percentage of the population is immune.
* COVID-19 Pandemic Disruptions: The pandemic significantly disrupted routine immunization services, leading to delays in vaccination campaigns and reduced access to healthcare.
* Misinformation and Vaccine Hesitancy: the spread of false details about vaccine safety and efficacy has fueled vaccine hesitancy, leading some parents to delay or refuse vaccination for their children. This is a global issue, but particularly impactful in regions with existing trust deficits.
* Migration and Mobility: Increased migration and travel patterns can facilitate the spread of measles across borders, especially when individuals are unvaccinated.
* Weak Surveillance Systems: In some areas, weak disease surveillance systems hinder the early detection and rapid response to outbreaks.
PAHO’s Urgent Call to Action: A multi-Pronged Approach
PAHO is urging countries to take immediate and decisive action to address the measles resurgence. The recommended strategy involves a comprehensive, multi-pronged approach:
- Strengthen Vaccination Campaigns: Prioritize and intensify vaccination campaigns, particularly targeting children under five and ensuring access for all. Catch-up campaigns are crucial to immunize those who have missed their doses.
- Improve Surveillance systems: Enhance disease surveillance systems to detect and respond to outbreaks quickly and effectively. This includes strengthening laboratory capacity and improving reporting mechanisms.
- Combat Misinformation: Launch public health campaigns to address misinformation about vaccines and promote the benefits of immunization. Partner with trusted community leaders and healthcare professionals to build confidence in vaccines.
- Strengthen Healthcare Systems: Invest in strengthening healthcare systems to ensure access to quality healthcare services, including vaccination and treatment for measles.
- Cross-Border Collaboration: Enhance collaboration between countries to coordinate vaccination efforts and prevent the cross-border spread of measles.
Measles Complications: What You Need to Know
Measles is a highly contagious viral disease that can cause serious complications, even in previously healthy individuals. Understanding these risks is vital for promoting vaccination.
* Pneumonia: One of the most common and serious complications, especially in young children.
* Encephalitis: Inflammation of the brain, which can lead to permanent neurological damage.
* Ear Infections: Can result in hearing loss.
* Diarrhea and Dehydration: Common symptoms that can be particularly dangerous for infants and young children.
* Subacute Sclerosing Panencephalitis (SSPE): A rare but fatal brain disease that can develop years after a measles infection.
Benefits of Measles Vaccination: Protecting Individuals and Communities
Vaccination remains the most effective way to prevent measles and its complications.The benefits extend beyond individual protection:
* Individual protection: The measles, mumps, and rubella (MMR) vaccine provides long-lasting immunity against the disease.
* Herd immunity: High vaccination coverage protects those who cannot be vaccinated, such as infants too young to receive the vaccine or individuals with weakened immune systems.
* Reduced Healthcare Costs: Preventing measles outbreaks reduces the burden on healthcare systems and lowers healthcare costs.
* Economic Benefits: Preventing illness and disability contributes to a more productive workforce and a stronger economy.
Practical Tips for Parents and Caregivers
* Check Vaccination Records: Ensure your children are up-to-date on their MMR vaccinations.
* Consult Your Healthcare Provider: If you are unsure about your child
