Baja California Sur reports 186 dengue cases; Los Cabos leads with 74

Baja California Sur is grappling with a significant dengue outbreak, recording 186 confirmed cases so far this year. This figure places the state fifth in Mexico for dengue infections. The municipality of Los Cabos is particularly affected, with 74 cases, nearly 40% of the state's total, leading authorities to prioritize fumigation efforts in the area.

Nationally, Sonora leads with 992 cases, followed by Veracruz (614), Tabasco (488), and Sinaloa (447). Baja California Sur's 186 cases include 107 with warning signs and 10 identified as severe, while 69 are classified as non-severe.

With the onset of the rainy season, state health secretary Ana Luisa Guluarte Castro emphasized the critical need for public cooperation. Residents are urged to keep their patios clean and eliminate any standing water, which serves as breeding grounds for the Aedes aegypti mosquito, the primary vector for dengue. While fumigation campaigns are underway, covering approximately 800 hectares in 20 neighborhoods in Los Cabos, Guluarte stressed that these efforts primarily target adult mosquitoes. Eliminating breeding sites in homes remains a crucial preventative measure.

Brigades from the Vector Control Program are also conducting door-to-door inspections to apply larvicide in water storage containers, further preventing mosquito reproduction. Baja California Sur registered 677 dengue cases in 2025, and health officials warn that August and September, months typically associated with increased rainfall from tropical cyclones, pose a heightened risk for a surge in cases. The state's Civil Protection Council is calling for continued vigilance and preventative actions.
