“…Indoor locations have a relative humidity < 40% which indicates higher chances of airborne SARS-CoV-2 transmission. Moreover, SARS-CoV-2 infection occurs in cool, dry, air-conditioned indoor environments 43 , 44 and during cold weather, people mostly stay indoors, which further potentiates transmission 45 . Presently, the USA is setting up policies which suggest maintaining indoor temperatures between 20 and 24 °C and RH around 20–60% 46 .…”

The continuing evolution of SARS-CoV-2 variants not only causes a long-term global health concerns but also encounters the vaccine/drug effectiveness. The degree of virus infectivity and its clinical outcomes often depend on various biological parameters (e.g., age, genetic factors, diabetes, obesity and other ailments) of an individual along with multiple environmental factors (e.g., air temperature, humidity, seasons). Thus, despite the extensive search for and use of several vaccine/drug candidates, the combinative influence of these various extrinsic and intrinsic risk factors involved in the SARS-CoV-2 virus infectivity has yet to be explored. Previous studies have reported that environment temperature is negatively associated with virus infectivity for SARS-CoV-2. This study elaborates on our previous findings, investigating the link between environmental temperature and other metabolic parameters, such as average total cholesterol and obesity, with the increase in COVID-19 cases. Statistical analysis conducted on a per country basis not only supports the existence of a significant negative correlation between environmental temperature and SARS-CoV-2 infections but also found a strong positive correlation between COVID-19 cases and these metabolic parameters. In addition, a multiphase growth curve model (GCM) was built to predict the contribution of these covariates in SARS-CoV-2 infectivity. These findings, for first time, support the idea that there might be a combinatorial impact of environmental temperature, average total cholesterol, and obesity in the inflation of the SARS-CoV-2 infectivity.

“…There are many researches about temperature and humidity such as: temperature should range from 17 to 28 • C, and the RH should be 40 to 70% (Guo et al, 2020), the best humidity should range from 40 to 60% at workplace and a general indoor temperature of 21-23 • C (Guo et al, 2020). In a study by Turki et al (2021) in the optimum indoor meteorological status such as temperature 23 • C, relative humidity 53%, without sunlight, the aerosolized SARS-CoV-2 may stay infectious for up to 16 h (Habeebullah et al, 2021). Some studies say that COVID-19 deactivation is best at around 50-80°C and 40-50% relative humidity (Rezaei et al, 2020).…”

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.

“…One research demonstrated that the majority of COVID-19 patients infected at home became infected in a cold, air conditioned, arid, and bad-ventilated indoor condition [17]. Masoumbeigi and colleagues mentioned that mechanical air conditioning and natural ventilation are available methods that can be used for air cleaning in hospitals [18].…”

Currently, (2019-2020) 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. The prevention of air pollutants (i.e., biological, particles, chemicals, and smoke) at the resource has the highest efficiency to keep safe air. 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? We systematically searched Embase, PubMed/MEDLINE, Scopus, PubMed Central (PMC), Google Scholar databases as well as medRxiv by using the following key-words: ‘COVID-19’, ‘healthcare settings’, ‘prevention’, ‘ventilation’, ‘Hospital, ‘Infection’, and ‘Air changes per hour. A total of 26 eligible articles were identified. The literature denotes that temperature, relative humidity, and ventilation and air conditioning systems have beneficial effects to prevent COVID-19 infection. 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.
