Is it time to consider shreds of epidemiological and environmental evidence associated with high transmission of COVID-19?

Novel coronavirus named COVID-19 that emerged in late December from Wuhan affected almost the entire globe. Recent studies provided new insight into the high transmission of the disease. This review explores the current evidence of epidemiological and environmental factors associated with high transmission of COVID-19. Even transmission and symptoms found among cats, dogs, ferrets, and tiger suggested low species barrier of the virus. The airborne transmission was found even up to 4 m, and fecal transmission with virus particles and RNA in sewage and wastewater suggests rethinking containment strategies. However, temperature, humidity, and pollution were also associated with transmission and mortality trends of COVID-19. To better mitigate and contain the current pandemic, it is a need of hours to consider the recent shreds of evidence to prevent further spread and require detailed investigations of these evidences by extensive epidemiological and meteorological studies.
