On 13 July the federal ministry reported seven lives confirmed dengue deaths and produced 126 severe infections, Mexican health officials intensified vector‑control cases nationwide, with 1,648 patients showing warning signs and 1,400 non‑severe infections. The highest case totals were in Nogales, Sonora. Larval treatment was applied Sonora (898), Veracruz (499), Tabasco (440), Sinaloa (439) and Baja California Sur (178); Sinaloa led with 30 severe cases. Officials reiterated advice to eliminate standing water, cover containers and remove breeding sites. The same week, Nogales repeated larval treatment of 500 homes, aerial spraying of 40 kg of larvicide and aerial insecticide were sprayed over 60 ha, reaching roughly 1,500 residents, while ha and door‑to‑door education urged people to eliminate standing water. The neighbouring Spanish town of Salobreña, which had identified West Nile‑virus‑carrying mosquitoes, also stepped up education, while Salobreña intensified fumigation, added traps and launched a public information campaign, with maintained water‑site surveillance of stagnant‑water sites scheduled through 20 August. By the end of July, heavy Heavy rains and unusually high temperatures spurred in late July triggered a broader surge in mosquito populations of mosquitoes across Mexican cities. Dr. Dr Romero A. Saldaña Vázquez of IBERO Puebla warned that untreated water in drains, containers flower pots and household items creates other containers fuels breeding grounds, and he urged residents to remove standing water, use screens, wear protective clothing and apply repellents, especially during peak activity periods. Both regions continue to emphasize community participation By early August the Yucatán Peninsula recorded a 102 % rise in dengue, with 201 confirmed cases—most (167) in Quintana Roo—prompting intensified fumigation and ongoing monitoring to curb disease transmission. public warnings.
