Tropical climate, waterlogging... reasons why Delhi is prone to dengue

‘Stagnant water bodies become perfect breeding grounds for mosquitoes’

Delhi is witnessing a significant surge in vector-borne diseases, with the city recording its highest-ever weekly dengue cases this year. Between January and September, the capital has seen 870 dengue cases, with 197 of those reported in the week ending September 14 alone.

In the same period, malaria cases have reached a three-year high with 299 reported, 37 of which occurred in the second week of September. Chikungunya cases are also rising, totaling 36 so far this year — four times higher than the entire count in 2023. Speaking to Millennium Post, experts highlighted several factors making Delhi particularly vulnerable to these diseases, including its tropical climate, waterlogging from monsoons and inadequate waste management. Last year, the city experienced its third-worst dengue outbreak in the past 8 years, peaking in August and September with a total of 9,266 cases and 19 fatalities, according to the MCD records.
