COVID-19 is a disease caused by the Severe Acute Respiratory Syndrome Coronavirus - 2 (SARS-CoV-2), first reported in Wuhan, China, in December 2019. Since then, it has caused a pandemic with public, economic, social, educational, and worldwide health crises; causing more than 500 million confirmed cases and 6.2 million deaths, according to the World Health Organization (WHO). Peru has been one of the most countries affected by COVID-19 worldwide, with more than 3,5 million confirmed cases and 212,000 deaths as of April 2022. Peru has had several limitations to control the pandemic; one of them is the inadequate monitoring of existing new cases of COVID-19 in real-time (incidence). This can be achieved with mass screening tests and clinical diagnoses at the national level. However, these tests are expensive, do not reach the entire population, and are not 100% reliable (false positives or negatives). The monitoring of SARS-CoV-2 RNA in wastewater consists of measuring the viral RNA discharged by the infected population into the sewage network system of a region, offering a reliable, unbiased, and low-cost alternative, complementing the indicators of medical care. This study proposes and validates implementing decentralized monitoring of SARS-CoV-2 RNA in the sewage network of the three most populated cities in Peru: Metropolitan Lima, Callao, and Metropolitan Arequipa. The data on viral loads showed the same trends as health indicators, such as daily positive cases or deaths from COVID-19. In addition, we were able to identify contagion hotspots within the monitored urban areas that can contribute to decision-making by health authorities, including actions to combat the COVID-19 pandemic. Overall, the results support wastewater monitoring for SARS-CoV2 RNA as a valuable and cost-effective tool to monitor the COVID-19 pandemic in the Peruvian context.
