Abstract

A novel coronavirus (COVID-19) was detected in China at the final of 2019 and has since caused a worldwide pandemic. This virus is transferred by airborne, sneezing, and speaking. Because COVID-19 is highly infectious through airborne contamination, the high infection risk in the medium environment is a serious problem for both healthcare workers and patients.
This literature – overview provides a description of the methods to reduce infection of COVID-19 such as indoor quality, non-pharmaceutical, and air controllers. The main importance has been on how to enhance the air quality in isolation rooms. The review articles concentrate on theoretical, computational simulation, experimental investigation, or combination. From the discussion of the articles, there exist the locations of ventilation systems (air supply and exhaust opening) that play an important role in reducing the infection risk and the amount of removed or concentrated particles in isolation rooms. Beside that, types of wearing masks and indoor air quality such as temperature and relative humidity are also important issues.
