text: Coronavirus occurrence surveillance and persistence in wastewater The coronavirus disease COVID 19 outbreak reported in China in December 2019 has spread throughout the world The WHO declared it as a pandemic in March 2020 The pandemic severely affected public health and the global economy Many studies conducted on the coronavirus have helped us to elucidate its pathogenicity and pathophysiology However it is important to study the behavior of the pathogen in the environment to develop effective control measures While studying the persistence and transmission of viruses in drinking water and wastewater systems a low concentration of coronavirus and its nucleic acids have been detected in municipal wastewaters This could be due to their high susceptibilities to degradation in aqueous environments Epidemiological study on coronaviruses in wastewater will serve two purposes i e in early detection of outbreak and in identifying asymptomatic carriers In such cases the epidemiological study will help in early detection of the presence of the virus in the community Secondly it will help in knowing if there are asymptomatic carriers as such people do not show any signs of symptoms but shed the viruses in feces The present review focuses on the epidemiological surveillance of wastewater for coronaviruses as in recent years these are increasingly causing global pandemics In this review we have discussed the four pertinent areas of coronavirus study 1 occurrence of coronavirus in wastewater 2 wastewater based epidemiological surveillance of coronaviruses 3 epidemiological surveillance tools used for detection of coronaviruses in sewage and 4 persistence and sustainability of coronaviruses in wastewater
