"Things are improving day-by-day. We are taking care of each and everything, be it health or any other issue. All athletes are living here happily and comfortably," Walia told reporters outside the Athletes Village.
"Our officers have already sprayed anti-larvae insecticides all over the Games Village. About 400 athletes have visited the polyclinic inside the Village and there has been no case of dengue.
"We have a team of medical officers and they are coordinating to deal with any health related issues. We have sufficient number of doctors to treat athletes for any small or big disease. All test can also be conducted at this clinic," she added.
The Delhi Health Minister also said the accreditation problems of medical officials for the Delhi Games, starting Sunday, have been sorted out.
"Accreditation is a matter related to the Organising Committee. There were some problems with police verification and other issues but most of the accreditation process is done. Almost all the doctors have got their cards," Walia said.
"At Games Village we have a team of expert doctors, paramedics and all facilities like ambulance, masseurs to take care of any health concern," she said.
Fears of a dengue epidemic is one of the reasons that kept the foreign athletes away from the Commonwealth Games, which has been marred by shoddy construction, corruption charges and issues related to hygiene in the village.
