US Measles Cases Reach 35-Year High Amid Falling Vaccination Rates

Measles cases in the United States have climbed to their highest level in 35 years, according to recently released public health data, renewing concern among officials about declining vaccination coverage.

A troubling trend

Public health officials said the rise has been concentrated in communities with lower childhood vaccination rates, with several outbreaks traced to unvaccinated individuals travelling internationally.

Measles is among the most contagious diseases known, health experts noted, meaning even small drops in vaccination coverage can allow the virus to spread rapidly through a community.

• Case counts have surpassed levels not seen since the disease was declared eliminated in the US in 2000
• Multiple states have reported clusters linked to school and community settings
• Officials are urging renewed uptake of the MMR vaccine

Calls for renewed vaccination efforts

Health departments in affected states have ramped up outreach campaigns, officials said, targeting communities with historically lower immunisation rates.

Officials warned that continued declines in vaccination coverage could jeopardise the country's previous elimination status for the disease, a designation achieved after decades of public health effort.

Pediatricians are urging parents to ensure children remain up to date on the MMR vaccine ahead of the coming school year, according to medical associations tracking the outbreak.
