“…This possible transmission route raises serious concerns, especially in low-income countries where raw wastewater is discharged directly into natural water bodies or through inefficient wastewater treatment plants (Figure 1). The presence of SARS-CoV-2 in natural water has been reported by many studies [9,49]. Guerrero-Loterra et al [23] reported the presence of SARS-CoV-2 in urban rivers with low sanitation facilities, indicating the transmission of the viral particles from untreated wastewaters and increasing the threat of COVID-19 to the environment and human health.…”

Impacts of COVID-19 on the Aquatic Environment and Implications on Aquatic Food Production

The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), resulted in ecological changes of aquatic ecosystems, affected the aquatic food supply chain, and disrupted the socio-economy of global populations. Due to reduced human activities during the pandemic, the aquatic environment was reported to improve its water quality, wild fishery stocks, and biodiversity. However, the sudden surge of plastics and biomedical wastes during the COVID-19 pandemic masked the positive impacts and increased the risks of aquatic pollution, especially microplastics, pharmaceuticals, and disinfectants. The transmission of SARS-CoV-2 from wastewater treatment plants to natural water bodies could have serious impacts on the environment and human health, especially in developing countries with poor waste treatment facilities. The presence and persistence of SARS-CoV-2 in human excreta, wastewaters, and sludge and its transmission to aquatic ecosystems could have negative impacts on fisheries and aquaculture industries, which have direct implications on food safety and security. COVID-19 pandemic-related environmental pollution showed a high risk to aquatic food security and human health. This paper reviews the impacts of COVID-19, both positive and negative, and assesses the causes and consequences of anthropogenic activities that can be managed through effective regulation and management of eco-resources for the revival of biodiversity, ecosystem health, and sustainable aquatic food production.

“…Thus, turbid rivers and lakes with high suspended solids contents are more susceptible to carrying viral particles and form an important route for the viral spread in a community. Wang et al [49] reported that river hydrology plays an important role in the long transmission route of SARS-CoV-2.…”

“…For example, several studies used the SEIR model to evaluate the relationship between meteorological conditions (temperature and relative humidity) and COVID-19 in China, but the results were inconsistent due to the different input parameters of their models ( Pan et al, 2021 ; Guo et al, 2020 ; Shi et al, 2020 ). Besides, to allow for over-dispersion of COVID-19 data, some studies used the generalized linear model with negative binomial distribution to fit the relationship between environmental factors and COVID-19 based on R software with "MASS" package ( Liu et al, 2020 ; Wang et al, 2020 ). A limitation of the generalized linear model is that it can’t fit the nonlinear-lagged effects between environmental factors and COVID-19.…”

With the global lockdown, meteorological factors are highly discussed for COVID-19 transmission. In this study, national-specific and region-specific data sets from Germany, Italy, Spain and the United Kingdom were used to explore the effect of temperature, absolute humidity and diurnal temperature range (DTR) on COVID-19 transmission. From February 1 st to November 1 st , a 7-day COVID-19 case doubling time (Td), meteorological factors with cumulative 14-day-lagged, government response index and other factors were fitted in the distributed lag nonlinear models. The overall relative risk (RR) of the 10th and the 25th percentiles temperature compared to the median were 0.0074 (95% CI: 0.0023, 0.0237) and 0.1220 (95% CI: 0.0667, 0.2232), respectively. The pooled RR of lower (10th, 25th) and extremely high (90th) absolute humidity were 0.3266 (95% CI: 0.1379, 0.7734), 0.6018 (95% CI: 0.4693, 0.7718) and 0.3438 (95% CI: 0.2254, 0.5242), respectively. While the DTR did not have a significant effect on Td. The total cumulative effect of temperature (10th) and absolute humidity (10th, 90th) on Td increased with the change of lag days. Similarly, a decline in temperature and absolute humidity at cumulative 14-day-lagged corresponded to the lower RR on Td in pooled region-specific effects. In summary, the government responses are important factors in alleviating the spread of COVID-19. After controlling that, our results indicate that both the cold and the dry environment also likely facilitate the COVID-19 transmission.

“…Of the 20 studies, three investigated two basic strategies to control COVID-19, including effective ventilation, and social distancing (Sun and Zhai, 2020). One study conducted on the effect of hydrological parameters (river length, lake area, rain, and water resources) on the SARS-CoV-2 pandemic reported that hydrological parameters play an important role in SARS-CoV-2 spread (Wang et al, 2020). Jayaweera et al reported that ventilation may cause transmission of the virus to taxi passengers (Jayaweera et al, 2020).…”

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