Resumen

We conduct statistical analysis of correlations for pre-alert system of the infection in population by wastewater screening of SARS-CoV-2 genomic fragments using qRT-PCR. We analyze data on surveillance of SARS-CoV-2 in wastewater as an epidemiological tool to anticipate outbreaks in Chile and Peru. We found there exists a positive relationship between genomic copies in wastewater and reported cases, and the relationship is of probabilistic nature.
