Ventilation Systems and COVID-19 Spread: Evidence from a Systematic Review Study

The main transmission mechanism of COVID-19 is through close contact, aerosols, droplets, and fomites the disease in closed spaces. In this study, importance ventilation preventing expansion reviewed. total, 20 articles are obtained results show that has a crucial role indoor air environments. However, it should be used properly; otherwise, will cause further disease, as suggested for SARS. Appropriate can effectively prevent COVID-19, more effective if combined with particle filtration disinfection. benefit highly polluted outdoor conditions an important field to investigated future studies. Finally, six basic control strategies include: hand hygiene, social distancing, screening case finding, isolation separating, decontamination disinfection, ventilation. We hope present study help researchers health decision-makers designing programs perceive factors related expansion.
