Background on Measles Situation in Mexico

Mexico is currently experiencing a surge in measles cases, primarily attributed to the low vaccination coverage during the COVID-19 pandemic. According to Mexico’s Secretary of Health, David Kershenobobich Stalnikowitz, only 87% of the target population has been vaccinated against measles.

Target Demographic and Current Vaccination Status

The age group most affected by measles is 0 to 4 years, with 1,149 confirmed cases and the highest incidence rate (11.04 per 100,000 individuals under 4 years old). The second and third most affected groups are 25 to 29 years (593 cases) and 30 to 34 years (487 cases).

Government Response and Vaccination Strategy

Kershenobich acknowledged that children did not receive vaccinations regularly during the COVID-19 pandemic, leading to lower vaccination rates among this demographic. He emphasized that the goal is to reach 95% vaccination coverage.

The current measles outbreak originated from Texas, and the strategy has focused on containing the spread in Chihuahua. Kershenobich mentioned that migrant workers in Chihuahua still need to be vaccinated.

He also clarified the vaccination schedule: 6 months, 12 months, and 18 months for the first dose; a second dose at 6 years of age. Kershenobich stressed that vaccination should not be forced and encouraged people to voluntarily get vaccinated.

Measles Cases and Mortality in Mexico

As of Tuesday, September 23, Mexico reported a cumulative total of 4,653 measles cases, with eight new cases confirmed in the last 24 hours and a total of 21 deaths due to the disease.

Chihuahua has the highest number of cases (4,293) and 20 deaths, resulting in a measles incidence rate of 108.3 per 100,000 residents. Other states with notable cases include Sonora (97 confirmed cases, 1 death), Coahuila (55 confirmed cases), Guerrero (51 confirmed cases), Michoacán (25 confirmed cases), and Durango (22 confirmed cases).

Health Routes Announcement

On Tuesday morning, President Claudia Sheinbaum announced that the second phase of health routes will conclude next Friday.

“Remember that each month, we will deliver the necessary medications for primary, secondary, and tertiary healthcare levels—that is, health centers, hospitals, and specialty hospitals,” Sheinbaum said during the federal executive’s morning press conference.

The program delivers 147 types of medications and supplies to 8,342 health centers in 23 states affiliated with IMSS Bienestar.
