In July, Mumbai reports a sharp rise in several seasonal diseases alongside heavy monsoon rains, prompting the Brihanmumbai Municipal Corporation (BMC) to intensify surveillance and prevention efforts. BMC Public Health Department data cited across outlets show malaria cases more than doubled, rising from 655 in June to 1,380 in July (about a 111% increase). Leptospirosis also increases significantly, from 33 to 78 cases (about a 136% rise). Dengue cases rise from 266 to 466 (about 75%), while gastroenteritis increases from 603 to 851 (about 41%). Reports also indicate an increase in swine flu (H1N1) from 58 to 105 (about 81%), while chikungunya remains unchanged at seven cases in both months. COVID-19 cases increase from 27 to 58. In response, the BMC expands vector-control measures such as the “Zero Mosquito Breeding Campaign,” inspections of potential breeding sites, fogging in residential buildings and slum areas, and rodent-control actions linked to leptospirosis risk. The BMC urges residents to avoid water stagnation, maintain hygiene, use protective footwear in waterlogged areas, and seek medical care for symptoms such as fever, body ache, vomiting, or breathlessness.
