VOICED : Nuevo coronavirus ya estaba en aguas residuales de Italia en diciembre de 2019, según estudio

A study by the Italian Institute of Health found the new coronavirus in wastewater samples from northern Italy as early as December 2019, two months before the first official case. The research, confirmed by two labs, detected the virus's RNA in samples from Milan and Turin. No traces were found in October and November samples. This study aids in understanding the virus's early spread in Italy and aligns with findings from France and Spain, where the virus was detected in December 2019 and January 2020, respectively.
