Measles is surging again in Mexico, with nearly 12,000 confirmed cases and 32 deaths. The outbreak reveals widening immunity gaps driven by low vaccination coverage, healthcare inequalities, and disruptions to routine immunization—and serves as a warning that measles elimination cannot be taken for granted.
Measles is resurging across the Americas, with nearly 23,000 confirmed cases reported in 2026. Here’s what the latest PAHO data reveal about the outbreak and why vaccination remains our strongest defense.
Qualitative research helps explain why people accept, delay, or refuse vaccines. By combining findings from multiple studies, systematic reviews can guide more effective vaccination policies across Latin America.
A review of 56 studies reveals that vaccine hesitancy in Latin America is influenced by much more than misinformation. Trust in healthcare providers, cultural beliefs, access to vaccination services, and clear communication all shape vaccine decisions, offering valuable lessons for improving immunization coverage across the region.
Dengue remains a major public health threat across Latin America in 2026. Explore the latest PAHO outbreak data, affected countries, circulating dengue serotypes, and why health officials continue to emphasize surveillance, mosquito control, and early detection to prevent future epidemics.
