Yes. WHO recognises that in special situations such as in health care facilities, the COVID-19 virus can be transmitted by air currents. Therefore, following the ALARA (As Low As Reasonably Achievable) principle, it is important to minimise such a risk. In such cases, the HVAC system for the ICU’s and other areas of the hospital where COVID-19 patients are present can help to vent all air pollutants, including the virus. This can be accomplished through the ventilation of close common spaces with outdoor air and air filtration, i.e. through achieving and maintaining an elevated Indoor Air Quality (IAQ) by use of the HVAC system.
