Measles Outbreak Locations: A Global Overview
The global resurgence of measles is a serious public health crisis. In 2023, an estimated 10.3 million people were infected, resulting in 107,500 deaths – a stark reminder of the disease’s devastating potential, especially for young children. This alarming rise is directly linked to declining vaccination rates worldwide, a trend exacerbated by the COVID-19 pandemic. Understanding the current measles outbreak locations is critical for effective prevention and control strategies. This blog post will provide an in-depth analysis of the situation, focusing on global trends, specific regional outbreaks, and the implications for businesses and public health officials.
Measles, a highly contagious viral illness, easily transcends geographical boundaries, posing a significant threat wherever vaccination rates are low. The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) consistently emphasize the importance of achieving and maintaining high vaccination coverage (95% or greater with two doses of the measles-containing vaccine) to prevent and control outbreaks. Despite these recommendations, over 100 countries have experienced measles outbreaks in the last five years, impacting a substantial portion of the world’s children.
In 2023, major outbreaks were reported in 57 countries, with a concentration in parts of Africa, the Middle East, and Asia, particularly in regions with limited resources and inadequate healthcare infrastructure. The Democratic Republic of Congo reported the largest number of cases, with a staggering 311,500 infections. Other countries with significant outbreaks included India, Indonesia, Russia, Yemen, and Iraq. The WHO provides monthly updates on measles outbreaks, and provisional data from the CDC (based on WHO data) offers a glimpse into the most affected regions. For the most up-to-date information on the top 10 countries experiencing outbreaks between February and August 2025, please refer to the CDC website.
Measles Outbreak Locations: The United States
Despite officially eliminating measles in 2000, the United States continues to grapple with sporadic cases and outbreaks, largely attributed to unvaccinated individuals, often those returning from international travel. As of September 16, 2025, a concerning 1,491 confirmed measles cases have been reported across 42 jurisdictions, making 2025 the worst year for measles in over three decades. 38 outbreaks have been identified, with a significant 86% of confirmed cases directly linked to these concentrated events. Tragically, three deaths have been reported.
- Texas: Leading the nation with over 700 confirmed cases, Texas has tragically seen two unvaccinated children succumb to the disease. This highlights the devastating consequences of low vaccination rates.
- New York: Having experienced significant outbreaks in New York City (Williamsburg and Borough Park) in 2018 and 2019, prompting mandatory vaccination orders in affected areas, New York State and New York City continue to report cases in 2025. This underscores the persistent challenge of maintaining high vaccination rates even in areas with previously successful control measures.
- California: As of September 15, 2025, 20 confirmed cases have been reported across multiple jurisdictions, including Fresno, Long Beach, Los Angeles, Orange, Placer, Riverside, Sacramento, San Diego, San Mateo, Santa Clara, Tulare, Tuolumne, and Yolo. This widespread distribution emphasizes the need for robust statewide public health initiatives.
- Ohio and Kansas: Independent outbreaks in Ohio (11 cases) and Kansas (23 cases) in April 2025, particularly affecting unvaccinated children and linked to the Texas and New Mexico outbreaks, exemplify the ease with which measles can spread across state lines.
- New Mexico: With a notable increase to 65 cases in 2025, New Mexico demonstrates the rapid escalation potential of measles outbreaks.
Measles Outbreak Locations: Canada and Europe
The rise in measles cases is not limited to the United States. Canada and Europe are also experiencing increasing numbers. Alberta, Canada, is currently facing ongoing measles transmission across all zones, with the highest concentration of cases in the north, south, and central regions. A majority of cases involve unvaccinated children under 5 years old and those aged 5 to 17. Britain reported a staggering 2,911 confirmed measles cases in 2024, the highest annual number since 2012. Ukraine’s experience, with over 57,000 cases in 2019, remains a stark reminder of the potential for large-scale outbreaks in regions with low vaccination coverage.
The Impact of the COVID-19 Pandemic
The global decline in measles vaccination rates following the COVID-19 pandemic is a crucial factor driving the current resurgence. Millions of children have become vulnerable, significantly increasing the likelihood of widespread outbreaks. This underscores the need for robust vaccination campaigns and coordinated public health interventions to restore high vaccination coverage levels globally.
Practical Takeaways and Actionable Advice
For businesses and organizations, understanding measles outbreak locations is paramount for several reasons:
- Travel Risk Assessments: Businesses with employees who travel internationally need to incorporate measles outbreak locations into their risk assessments. This includes providing necessary vaccinations and preventative measures.
- Employee Health and Safety: Companies should prioritize employee health and safety by promoting vaccination and providing information about measles prevention.
- Supply Chain Disruptions: Outbreaks can potentially disrupt supply chains, particularly in regions with significant health crises. Businesses need to develop contingency plans to mitigate these risks.
- Public Relations: A proactive approach to public health issues can enhance a company’s reputation and demonstrate its commitment to social responsibility.
Conclusion
The ongoing global measles outbreaks highlight the critical need for sustained efforts to increase vaccination rates worldwide. By understanding the current measles outbreak locations and their associated risk factors, we can better prepare for and respond to future outbreaks.
