Countries across the Americas are facing a sharp rise in measles, recording their highest numbers in over twenty-two years. Disease experts explain that a combination of low vaccination rates and heavy international travel during the FIFA World Cup has driven the resurgence of this contagious virus.
Between January and August, the region recorded more than fifty-one thousand cases, which is almost triple the total from the previous year. Guatemala, Mexico, the United States, and Peru account for ninety-five percent of these cases. In response, the Pan American Health Organization urged governments to strengthen vaccination programs and improve rapid response measures.
Data reveals that seventy-three percent of the cases involved people who were not vaccinated. Overall immunization coverage remains below the ninety-five percent threshold needed for herd immunity. Only eighty-five percent of the population has received the two necessary doses of the vaccine.
Experts emphasize that travel mobility accelerates the spread of the virus. They recommend that local authorities identify why coverage rates are low and address these immunity gaps quickly.
