Construction delays, inclement weather, red tape if these were not enough reasons to worry Indian Olympic Association chief Suresh Kalmadi in the run up to the Commonwealth Games, then a possible dengue outbreak in New Delhi is sure to break him down to tears.

Union Health Minister Gulam Nabi Azad had gone on record last month that due to the construction work at the Commonwealth Games village across the Yamuna bridge and stoppage of the movement of fresh water, the river had become a breeding ground for the dengue fever and had warned that the situation may worsen in days to come.

And it has.

Dengue cases in the national capital have crosses last year's figure of 1,153.

The government has said that it would launch a special cleaning drive from September 6 to prevent breeding of mosquitoes even as it assured that the strain prevalent this year was far less lethal.

The Delhi government too has started a comprehensive programme throughout the capital to create awareness among people about what could constitute to spreading the virus.

"I am from the Delhi Health Department. Please show me the cooler," demanded an officer on routine inspection at a Madhuban Enclave residence near Punjabi Bagh.

Finding that the cooler was clean with not a drop of water inside he expressed satisfaction about the good maintenance work.

"Please change the water in the bottles outside, as this too can become a breeding ground for dengue virus," he said, before marching on to next house.

Faced with international advisories against travelling to India for the Games, the Union Health Ministry is now on a damage control mode.

Azad told media persons on Friday that from Monday a massive, coordinated cleaning operation for two days would be launched which would cover all roads, lanes and bylanes.

Municipal Corporation of Delhi, New Delhi Municipal Corporation, Central Public Works Department and the Cantonment Board would conduct the operation.

He said that the ministry has also asked agencies like Metro and CPWD to close work in areas where construction is over and use insecticides at the sites of under-construction projects.

"We have asked the Delhi government to ensure cleanliness in all government hospitals," Azad said, adding that MCD has been asked to form ward-level committees to take responsibility of cleaning up the areas.

The Health Minister said he has requested MCD to institute awards for best performing wards in the cleanliness drive.

The meeting also arrived at a decision to provide Resident Welfare Associations in all localities with the chemical 'Tamiphos', which can be sprayed to kill mosquitoes and their larvae."

"All government buildings, especially multi-storied ones, would be monitored to check for breeding in their water tanks, coolers and other places where water collects," Azad said.

MCD and NDMC have also been asked to open call centres where people can call and report any breeding or water logging.
