Health authorities in Mexico are implementing various strategies to control the spread of rickettsiosis. In the state of Sonora, the Public Health Secretariat has conducted over 500 epidemiological blockades, fumigated more than 5,000 homes, and treated thousands of dogs to combat tick populations. 

On a broader scale, officials in Ciudad Juárez have presented a binational prevention strategy during the Paso del Norte Binational Health Council conference. This coordinated effort involves municipal departments focused on animal welfare, ecology, and public services to manage the disease in the border region.
