Both Delhi and Gurgaon are experiencing a surge in dengue cases, with Delhi reporting over 900 cases this year and at least two deaths in the past week. The Municipal Corporation of Delhi (MCD) has ramped up efforts to control mosquito breeding through various measures, including fogging and legal actions against offenders. In Gurgaon, health authorities have identified multiple dengue hotspots and are conducting extensive inspections and fogging activities. The recent increase in cases has been linked to the humid conditions following significant rainfall, creating ideal breeding grounds for Aedes mosquitoes. Residents are urged to take preventive measures, such as eliminating stagnant water and using mosquito repellents, to mitigate the risk of infection. Experts stress the importance of seeking medical attention for flu-like symptoms instead of self-medicating, as the health system is currently under strain due to rising admissions related to dengue.
