Are workplaces safe from airborne Covid-19 transmissions?
Universiti Kebangsaan Malaysia researchers: Based on our (second) study, we found that enclosed spaces without any circulation of fresh air and with air-conditioning operations that recycle the same air can facilitate the transmission of the virus in the air via aerosols. This is why it is so important for buildings to have a good ventilation system. Houses should have their doors and windows kept open; in the case of offices and factories, their air-conditioning and ventilation system must be maintained regularly
