Despite the cold weather, many visit Bach Mai Hospital early in the morning on Wednesday for medical check-ups. Most of them are old people who have respiratory and heart diseases as well as problems related to their bones and joints.
Children are also vulnerable due to the sudden weather changes. Nguyen Van Quyet from Ung Hoa District, Hanoi, said that his three children had to go to hospital due to coughs and fever.
