With the arrival of the monsoon, Delhi has stepped up its fight against mosquito-borne diseases as the risk of dengue, malaria and chikungunya begins to increase. Waterlogging after rainfall creates ideal breeding grounds for mosquitoes, prompting the Municipal Corporation of Delhi (MCD), the Delhi Government and the Centre to launch an aggressive prevention campaign across the city.

Even before the rains gathered pace, anti-larval spraying was started in drains, waterlogged areas and residential colonies. MCD teams are also carrying out door-to-door inspections to identify stagnant water, issue notices and challans where required, and educate residents about preventing mosquito breeding around their homes.

Alongside civic action, hospitals across Delhi have strengthened their preparedness for the monsoon season. Health facilities have stocked essential medicines, ensured the availability of dengue testing kits and blood components, and reserved beds for patients suffering from vector-borne diseases. Hospitals have also been directed to provide priority treatment to patients diagnosed with dengue, malaria or chikungunya.

Health officials say Delhi's healthcare system now remains prepared throughout the year instead of waiting for the monsoon season. They believe the city is well-equipped to manage any rise in cases, with adequate supplies of medicines, diagnostic facilities and blood support already in place.

Officials also pointed out that only one spell of rain has occurred so far, and the number of vector-borne disease patients remains low. They said the real concern begins when heavy rainfall leads to water stagnation for several days, creating ideal conditions for mosquito breeding. At present, hospitals are largely treating routine illnesses, while surveillance teams continue to monitor the situation closely.

Delhi Mayor Pravesh Wahi said Union Health Minister J.P. Nadda recently chaired a high-level review meeting to assess Delhi's preparedness for dengue prevention. The meeting was attended by Delhi Health Minister Dr. Pankaj Kumar Singh, NDMC Vice Chairman Kuljeet Singh Chahal and senior officials.

According to the Mayor, the implementation of the National Dengue Prevention and Control Strategy was reviewed during the meeting, and the model developed in Delhi is now being adopted across the country. Under the National Dengue Control Programme, the Centre has strengthened disease surveillance, issued advisories, improved case management, expanded free diagnostic services, launched awareness campaigns, enhanced coordination among departments and provided financial support to states.

Quoting the Union Health Minister, the Mayor said dengue cases are currently low and the fatality rate stands at only 0.11 per cent. However, he stressed that all departments must remain fully prepared as the risk is expected to increase during the peak monsoon months.

Earlier, during a review meeting on June 24, Delhi Health Minister Dr. Pankaj Kumar Singh directed all hospitals to remain on alert and ensure there is no lapse in prevention or treatment of dengue, malaria and chikungunya. He said no death due to these diseases has been officially confirmed in Delhi this year, but emphasised that public participation remains the most effective weapon in controlling mosquito breeding.

To strengthen surveillance, the Delhi Government has designated 35 hospitals as Sentinel Surveillance Hospitals. These hospitals have been instructed to report every dengue, malaria and chikungunya case in real time through the Integrated Health Information Platform (IHIP). A dedicated control room has also been established at the Directorate General of Health Services headquarters to ensure immediate response and uninterrupted availability of resources.

People showing symptoms of mosquito-borne diseases can undergo free IgM ELISA testing at these hospitals. Whenever a patient tests positive, the concerned Municipal Corporation office is immediately informed. Civic teams then carry out anti-larval spraying, fogging and mosquito control measures around the patient's residence to prevent further spread of infection.

While the current situation remains under control, health authorities have urged residents not to lower their guard. With heavier rainfall expected in the coming weeks, officials say eliminating stagnant water, maintaining cleanliness and seeking early medical care for fever can play a crucial role in preventing a surge in mosquito-borne diseases across the national capital.

"With the monsoon becoming active, every resident has an important role to play in preventing malaria, dengue and chikungunya. Mosquitoes breed in clean stagnant water that collects in coolers, flower pots, buckets, discarded tyres and containers. People should ensure that water does not remain stagnant in or around their homes, clean water storage containers regularly, and allow civic teams to carry out inspections and anti-larval measures. Simple preventive steps taken by the community can significantly reduce the spread of these diseases. If anyone develops fever, severe body ache or other symptoms, they should immediately visit the nearest health facility instead of self-medicating. Early diagnosis and timely treatment not only improve recovery but also help prevent the spread of infection," said Dr. Ashok Rawat, Municipal Health Officer, Public Health Department, MCD.
