In Coahuila, Mexico, health officials and legislators are responding to the threat of rickettsiosis, a zoonotic disease transmitted by ticks, fleas, and lice. Early reports indicated 41 confirmed cases and 30 deaths as of August, prompting Deputy Edith Hernández Sillas to propose a reform to the Coahuila State Health Law to mandate the prioritization of rickettsiosis prevention and control. As the situation progressed, health authorities in the central region intensified surveillance and medical training. While 72 suspected cases were ruled out in Monclova and Frontera, seven positive cases and five deaths were confirmed in that region. To address the high mortality rate of untreated cases, medical specialists and experts from Texas have been involved in training approximately 150 doctors. Public health efforts are currently focusing on medical personnel training and community-level prevention, such as pet hygiene and waste management to eliminate tick habitats. By September 2026, State Health Secretary Eliud Aguirre Vázquez reported that the state has recorded 51 cases of rickettsiosis with 37 deaths, representing a lethality rate exceeding 70%. While the disease is present throughout the state, the highest concentration of cases is in the Comarca Lagunera region. Officials noted that late diagnosis remains a primary challenge because symptoms are often confused with other illnesses. In response, an epidemiologist from Mexico City is leading training sessions for medical professionals in both the public and private sectors across all 38 municipalities. These efforts have already included training 300 doctors in Torreón, alongside sessions in Monclova and Piedras Negras. Additionally, health jurisdictions are conducting fumigation activities as a preventive measure. By the end of September 2026, health authorities reported that the total number of confirmed cases rose to 58, with 42 deaths recorded. The mortality rate remains above 70 percent.
