Gujarat’s Health Department reported on World Mosquito Day, August 19, that malaria, dengue and chikungunya cases have all declined sharply this year compared with the same period in 2025. Data through epidemiological week 33 shows malaria cases down 45%, from 1,407 to 774; dengue down 39.1%, from 1,293 to 788; and chikungunya down 48.1%, from 154 to 80. ANI reported zero deaths from malaria or dengue during this period, and Prokerala’s coverage of the same health department release confirms the figures.
What is behind the drop
The state ran a two-phase house-to-house surveillance campaign this year, the first from April 27 to May 6 and the second from July 1 to 10. In the second phase alone, nearly 19,600 teams covered 6.51 crore people, collected 2.57 lakh blood samples and identified 28 malaria patients for treatment. Vector-control crews cleared 29.63 lakh mosquito breeding sites, fogged more than 3.21 lakh houses, and stocked 5,024 waterlogging-prone sites with larvivorous fish that eat mosquito larvae. Health authorities also expanded diagnostic capacity, with 42 medical-college-affiliated hospitals now running dengue and chikungunya testing, processing more than 95,000 serum samples this year.
Gujarat’s history with these diseases
Vector-borne disease outbreaks are a recurring monsoon-season concern in Gujarat’s cities, where waterlogging after heavy rain creates breeding conditions in urban drains, construction sites and open plots. Ahmedabad, Surat and Vadodara have all seen periodic dengue and chikungunya spikes in past monsoons, occasionally straining municipal hospital capacity in September and October. Sustained double-digit declines across all three major vector-borne diseases in the same year, if they hold through the rest of this year’s monsoon, would mark a genuinely unusual result compared with the state’s recent track record.
What it means for Gujarat residents
Fewer cases mean fewer families dealing with the lost workdays, medical bills and, in bad years, hospitalisations that come with dengue and chikungunya in particular, both of which can cause weeks of debilitating joint pain and fatigue even in mild cases. Free testing availability at 42 medical college hospitals also gives residents in smaller towns better access to confirmed diagnosis rather than relying on private labs, which matters for early treatment. The scale of the fogging and larvicide campaign additionally suggests municipal bodies put real resources into this year’s pre-monsoon and monsoon preparation rather than reactive spraying after outbreaks were already underway.
Outlook
Peak dengue and chikungunya transmission in Gujarat typically runs from August through October, so this year’s real test is still ahead. Health officials will need to sustain surveillance and larval-source management through the rest of the monsoon to hold onto these gains, particularly in low-lying urban pockets that flood repeatedly each year.
