“…Some authors have also reported the presence of SARS-CoV-2 strains in the wastewater generated from the isolation centers and nearby hospitals where COVID-19 patients are being managed (J. Wang et al, 2020 ; Ge et al, 2020 ; Feng et al, 2021 ; Chakraborty et al, 2021 ; Ahmed et al, 2021 ; Hong et al, 2021 ), while others studies reported the presence of SARS-CoV-2 RNA in water and wastewater collected from wastewater treatment plants ( Ahmed et al, 2020a ; La Rosa et al, 2020 ; Hasan et al, 2020 ; Haramoto et al, 2020 ; Mlejnkova et al, 2020 ; Peccia et al, 2020 ; Randazzo et al, 2020 ; Wang et al, 2020 ; Rimoldi et al, 2020 ; Medema et al, 2020 ; Hokajärvi et al, 2021 ; Chavarria-Miró et al, 2021 ; Kitamura et al, 2021 ; Saguti et al, 2021 ), which are of course do not necessarily indicate the infectivity of the virus ( Buonerba et al, 2021 ). However, few studies have reported the detection and isolation of infectious SARS-CoV-2 from different environmental samples such as wastewaters ( Bivins et al, 2020 ; Lee et al, 2020 ; Sala-Comorera et al, 2021 ).…”

The recent spread of severe acute respiratory syndrome coronavirus (SAR-CoV-2) and the accompanied coronavirus disease 2019 (COVID-19) has continued ceaselessly despite the implementations of popular measures, which include social distancing and outdoor face masking as recommended by the World Health Organization. Due to the unstable nature of the virus, leading to the emergence of new variants that are claimed to be more and rapidly transmissible, there is a need for further consideration of the alternative potential pathways of the virus transmissions to provide the needed and effective control measures. This review aims to address this important issue by examining the transmission pathways of SARS-CoV-2 via indirect contacts such as fomites and aerosols, extending to water, food, and other environmental compartments. This is essentially required to shed more light regarding the speculation of the virus spread through these media as the available information regarding this is fragmented in the literature. The existing state of the information on the presence and persistence of SARS-CoV-2 in water-food-environmental compartments is essential for cause-and-effect relationships of human interactions and environmental samples to safeguard the possible transmission and associated risks through these media. Furthermore, the integration of effective remedial measures previously used to tackle the viral outbreaks and pandemics, and the development of new sustainable measures targeting at monitoring and curbing the spread of SARS-CoV-2 were emphasized. This study concluded that alternative transmission pathways via human interactions with environmental samples should not be ignored due to the evolving of more infectious and transmissible SARS-CoV-2 variants.

“…The HVAC system with a proper design and operation can disinfect polluted air, provide fresh air, interfere with air transmission route and remove airborne respiratory droplets/aerosols. 5 In order to achieve and maintain standardized medical facilities with a high-quality disinfection hygiene, there is an urgent need to develop a systematic and reliable methodology to quantitatively evaluate and optimize routine disinfection devices and HVAC system towards efficient control of the airborne disease. This paper discusses advantages/disadvantages of different hospital disinfection methods and summarizes relevant quantitative design/simulation methods.…”

As the Coronavirus disease 2019 (COVID-19) epidemic spreads all over the world, governments of various countries are actively adopting epidemic prevention measures to curb the spread of the disease. However, colleges and universities are one of the most likely places for cluster infections. The main reason is that college students have frequent social activities, and many students come from different countries, which may very likely cause college campuses to be entry points of disease transmission. Therefore, this study proposes a framework of epidemic prevention work, and further explores the importance and priority of epidemic prevention works. First of all, 32 persons in charge of epidemic prevention from various universities in Taiwan were invited to jointly formulate a campus epidemic prevention framework and determined 5 dimensions and 36 epidemic prevention works/measures/criteria. Next, Bayesian best worst method (BWM) was used to generate a set of optimal group criteria weights. This method can not only integrate the opinions of multiple experts, but also effectively reduce the complexity of expert interviews to obtain more reliable results. The results show that the five most important measures for campus epidemic prevention are the establishment of a campus epidemic prevention organization, comprehensive disinfection of the campus environment, maintenance of indoor ventilation, proper isolation of contacts with confirmed cases, and management of immigration regulations for overseas students. This study provides colleges and universities around the world to formulate anti-epidemic measures to effectively reduce the probability of COVID-19 transmission on campuses to protect students’ right to education.
