Dense fog has enveloped the northern district of Kurigram for the last four days, causing extensive hardship to residents and visitors alike.
With the escalation of the cold spell, the number of patients, mostly children and elderly, is increasing on a daily basis at hospitals.
Those living in char areas, on riverbanks and low-income people are the worst sufferers of the cold wave, coupled with dew-like drops of rain.
The local meteorological office recorded a 13-degree Celsius temperature at 6 am on Sunday.
Day-labourer Rafiqul Islam, a resident from Kedar Union of Nageshwari Upazila, said it is hard to endure the cold wind coupled with dense fog. "Hands and legs get iced while working," he added.
Autorickshaw driver Ashraful Hossain said they have to operate vehicles with headlights or slowly as close distances cannot be seen due to the fog.

Subal Chandra Sarkar, acting officer of the Kurigram weather office, said that the district may experience two to three more cold waves after falling temperatures this month.
