Study reveals survival time of SARS-CoV-2 in wastewater: Implications for public health PublicHealth SARSCoV2 Coronavirus Disease COVID ViralSurvival Effluent STOTEN_journal Tulane MorganStateU uOttawa uarizona
By Dr. Priyom Bose, Ph.D.Apr 25 2023 The rapid global transmission of Severe Acute Respiratory Syndrome Coronavirus-2 led to a pandemic commonly known as Coronavirus Disease 2019 . To date, this pandemic has affected approximately 686 million people and claimed more than 6.8 million lives worldwide. Even though this virus is primarily transmitted through respiratory droplets or direct contact with an infected person, SARS-CoV-2 has also been detected in feces.
Another study pointed out that SARS-CoV-2 survived for 1.7 days in wastewater at room temperature. The viability of SARS-CoV-2 was found to be greater in filtered river water and wastewater compared to unfiltered river water and wastewater samples. Study Findings A gradual decline in the infectivity of SARS-CoV-2 was observed in the three wastewater matrices. Consistent with previous studies, this study revealed a quick decrease in infectivity in unfiltered and filtered raw wastewater compared to secondary effluent. This finding indicates rapid SARS-CoV-2 inactivation in complex matrices compared to simpler matrices.

A rapid and affordable in vitro model to test SARS-CoV-2 susceptibility in animal speciesResearch investigates the susceptibility of seven bat species to SARS-CoV-2 by expressing their ACE2 receptor in a non-permissive avian cell line. The study found that all seven bat species were susceptible to SARS-CoV-2, but the level of virus replication differed between bat species and virus variants.
