The advisory issued by the principal scientific advisors office said, “Ventilation is a community defense that protects all of us at home or at work. Introducing outdoor air in offices, homes and larger public spaces is advised. Measures to improve ventilation in these spaces must be taken up on urgent priority in urban and rural areas alike, recommendations for hutments, homes, offices and large centralized buildings are given. Simple strategic placement of fans, open windows and doors, even slightly open windows can introduce outdoor air and improve the air quality inside.”

Introduction of cross ventilation and exhaust fans will be beneficial in curtailing the spread of the disease.

In buildings with central air-management systems improving central air filtration/increased filtration efficiency is especially helpful when enhanced outdoor air delivery options are limited. In offices, auditoriums, shopping malls etc., use of gable fan systems and roof ventilators are recommended. Frequent cleaning and replacement of fiters is highly recommended.
