NEW DELHI - Factory worker Mohammad Awwal is gripped by fever, sweats and the sort of agonising aches that mean his condition is sometimes called "breakbone disease". It's an annual plague in India and a hidden epidemic, say experts.
Dengue fever is a mosquito-borne disease with no known cure or vaccination that strikes fear into the citizens of New Delhi when it arrives with the monsoon rains - just as the scorching heat of the summer is subsiding.
Hospital wards are overwhelmed and tales abound of deaths and cases while New Delhi public authorities insist that only 3,500 have fallen sick so far this year - with only five fatalities.
"I took him first to a government hospital. I was shocked to see that it was packed with dengue patients. There was not even a single bed available," said Awwal's mother, Mehrunissa, sitting in her one-room shack in east Delhi.
She is now treating him at their home, giving him multi-vitamins, paracetamol and water as he lies on the floor with two pillows and a bedsheet but no mattress.
In a sign that this year's outbreak could be as bad as record-breaking 2010, the city's largest public hospital, Hindu Rao, announced earlier this month that it had suspended all routine surgeries to make room for more dengue patients.
The Delhi government has blamed prolonged monsoons for the hike in infections, but says it has added beds at hospitals and increased resources for spraying insecticides to tackle the mosquito menace.
"It's nothing to worry about, there is no crisis," Charan Singh, additional director of Delhi health services, told AFP, dismissing allegations that the city of 17 million under-reports the problem.
"It is a lot of hype going on... The government is in action and we report all cases according to international guidelines," he added.
