The air in Colombo is polluted and there is no mask that can prevent inhailing polluted air.
Therefore individuals in high-risk categories such as pregnant mothers, infants, children, the elderly, should take an extra precaution against such pollution, Consultant Community Physician attached to the Environmental and Occupational Health Unit of the Health Ministry, Dr.
Inoka Suraweera said.
Patients suffering from various other respiratory diseases, people who work in open air such as traffic police officers, and labourers are also among the high-risk groups, she said.
