Overview
- State data to the week ending June 13 show Sonora has 61 confirmed rickettsiosis cases and 22 deaths, increases of about 33% in cases and 29% in deaths versus 2025.
- Municipal hotspots in Sonora concentrate cases in Hermosillo, Guaymas, Navojoa and Cajeme, with Cajeme reporting six of the 22 deaths.
- Baja California has studied roughly 300 suspected cases, confirming 65 infections and recording 28 deaths in 2026, and officials report lethality has fallen to about 40% after clinician training and earlier detection.
- Local responses in both states include fumigation, entomological investigations, pet deworming and sterilization campaigns, and public warnings to seek care within five days of symptom onset for timely treatment.
- Fatal victims skew young, with an average age of about 34 and equal numbers of men and women, which health authorities say underscores the need to expand early detection, testing and municipal sanitation to curb further deaths.
