Mexico's most populous state has announced the deployment of enhanced health screening measures at schools, including temperature checks and recommendations for face mask usage among students and staff. This move comes as the nation confronts a significant and expanding measles outbreak, with confirmed cases now reported across all 32 states.
Nationwide Outbreak and State Responses
The decision by Mexico state, which borders Mexico City on three sides, follows similar preventative actions taken last week in Jalisco, the epicentre of the country's largest outbreak. In Jalisco, masks have been made mandatory in schools across its capital, Guadalajara, Mexico's second-largest city. This marks the first such public health mandate in Mexico since the COVID-19 pandemic, prompted by urgent calls from medical groups.
Current Case Numbers and Spread
As of 6 February, Mexico had recorded 2,143 confirmed measles cases nationwide, with nearly 6,000 additional suspected cases under investigation. Jalisco alone accounted for over half of these confirmed infections, though the virus has spread from northern to southern borders. The initial surge began last year in the northern border state of Chihuahua, traced to an unvaccinated eight-year-old Mennonite boy who had visited relatives in Seminole, Texas, a known centre of the US outbreak. While the Chihuahua outbreak is now under control, the disease's presence is widespread.
Health Measures and Vaccination Efforts
Mexico state Health Secretary Macarena Montoya Olvera stated on Monday that the outbreak in the state is under control, with cases so far being light, though the federal government has confirmed 40 cases there. The state's health department will implement temperature checks upon school entry and renew vaccination campaigns. Additionally, classes were recently suspended in 15 schools in Jalisco and the central state of Aguascalientes due to outbreaks of the highly contagious airborne virus.
Regional and Global Context
The Pan American Health Organization issued an epidemiological alert last week following a surge of measles cases across the Americas. Scientists attribute rising outbreaks across the hemisphere to declining vaccination rates. In a concerning development, Canada lost its measles-free status in November, and the same could potentially happen to the United States and Mexico if the current trend continues.
Local Initiatives and Future Outlook
Mexico City has launched an aggressive vaccination campaign, with 166 confirmed cases as of last Friday. Jalisco health authorities have mandated masks in Guadalajara schools across seven specific neighbourhoods for the next 30 days. As the situation evolves, health officials emphasize the importance of vaccination and preventive measures to curb the spread and protect public health.
