“…According to recent studies [4,6,[30][31][32], the degree of pollution in the aquatic systems in Romania decreased with the decrease in the incidence of COVID-19 cases. Post-pandemic effects can be seen in the horizontal transmission of acquired antibiotic resistance and the perpetuation of resistant bacteria in aquatic environments, with impacts on population health.…”

The COVID-19 pandemic was a challenge for the whole world, and it had major secondary effects on humans and environmental health. The viral infection induced, in many situations, secondary bacterial infections, especially enteric infections, by destabilizing the balance of the gastrointestinal microbiota. The large-scale use of antibiotics and biocides for both curative and preventive purposes has resulted in an increase in bacterial resistance, and at the same time, the possibility of pathogenic microorganism multiplication and their dissemination to natural environments. Wastewater is the main vector of fecal microorganisms that favors their dissemination into natural aquatic ecosystems. The present paper aims to analyze the effect of the COVID-19 pandemic on the microbiological quality of wastewater from sewage treatment plants in Romania and its impact on receiving rivers. In order to highlight different and important areas in Romania, three cities from the east, center and west were selected for a microbiological evaluation of their WWTP influents and effluents from the pre-COVID-19 period and during the COVID-19 pandemic peak period, when the COVID-19 pandemic had a direct impact on WWTP microbial compositions. Our study shows that a higher level of contamination with fecal bacteria is linked to a higher COVID-19 incidence. The increased usage of pharmaceutical compounds, in turn, increases the number of resistant bacteria reaching the environment via WWTP effluents.

“…In Romania, the Covid-19 pandemic steadily spread from second part of 2020, reaching an infection peak in the middle of 2021. Covid-19 spreading rate into population was mainly monitored by hospital units, but there were reports that it could be efficiently monitored by Covid-19 quantification in domestic wastewater [6]. Furthermore, many studies have shown that wastewaterbased epidemiology has become a practical approach for monitoring Covid-19 outbreaks.…”

“…Large amounts of wastewater, including those from hospital units, have been daily generated into the sewage system from where they reached as influents the municipal WWTPs [6,8]. The modern WWTPs could process large quantities of wastewater (up to 440 000 000m3/year) and subsequently help to maintain a safe urban development and a clean environment.…”

The Covid-19 pandemic was a challenge for the whole world and it had major second-ary effects on the health of the population and the environment. The viral infection caused, in many situations, secondary bacterial infections, especially enteric infections by destabilizing the balance of the gastrointestinal microbiota. The large-scale use of antibiotics and biocides both for curative and preventive purposes has determined an increase in bacterial resistance and at the same time the possibility of the multiplica-tion of pathogenic microorganisms and their transfer in natural environments. Wastewater is the main vector of faecal microorganisms that favour their dissemina-tion in natural aquatic ecosystems. The present paper represents a sub-study of the RADAR project with the aim of demonstrating the effect of the Covid-19 pandemic on the microbiological quality of wastewater from sewage treatment plants in Romania and its impact on receiving rivers. In order to highlight different and important areas of Romania, 3 cities from the east, center and west were selected for the evaluation of microbiological quality of influent and effluent sewage in WWTPs between ante-Covid-19 and the peak period of the Covid-19 pandemic, when the Covid-19 pandemic had a direct consequence on WWTPs processes. Our study showed the high-er contamination with fecal bacteria based on higher Covid-19 incidence. The in-creased usage of pharmaceutical compounds, at their turn, increased the number of resistant bacteria reaching the environment via WWTP effluents.
