Influence of Ventilation in Healthcare Facilities Prevention of Infection COVID-19: Systematic Review Study

Abstract

COVID-19 global pandemic is caused by a member of the Coronaviridae group. Some human viruses are spread from human to human by way of droplets or aerosols, but fewer viruses are persistently airborne in transmission, and the healthcare-associated epidemic of airborne viral infection are restricted to very few surrogates. In addition, it is one of the most efficient tools (i.e., the second one) for preventing inside air pollution through ventilation. To our aim was to perform a rapid literature review to answer the following question: does ventilation in healthcare facilities prevention of infection COVID-19?This study is a systematic review by searching among published articles in Embase, PubMed/MEDLINE, Scopus, PubMed Central (PMC), Google Scholar databases as well as medRxiv by using the following keywords: 'COVID-19', 'healthcare settings', 'prevention', 'ventilation', 'Hospital, 'Infection', and 'Air changes per hour.After investigating the information and quality of articles, 52 articles were included in this study. The literature denotes that temperature, relative humidity, and ventilation and air conditioning systems have beneficial effects to prevent COVID-19 infection.The results of this study demonstrated that many parameters basic strategy of control COVID-19 include: hand hygiene, social distancing, screening and case finding, isolation and separating, decontamination and disinfection, and effective ventilation. Thus, based on recommendations of CDC, WHO, and other studies effective ventilation is the most important transmission of respiratory disease control strategy, specially COVID-19.

Description of control measures, attitudes, and behaviours at a scientific conference with a confirmed COVID-19 case but no reported onward transmission, November 2021 England

“…Evidence of increased frequency in hand washing during the conference period in comparison to frequency before COVID-19, suggests that hand sanitiser points were utilised. The conference also ensured effective ventilation, which has been shown as a strategy for controlling COVID-19 transmission [ 16 ]. The conference was set up to minimise the risk of environmental factors on the spread of COVID-19 in this setting.…”
