Detection of Chikungunya Virus in Saliva and Urine Samples of Patients from Rio de Janeiro, Brazil. A Minimally Invasive Tool for Surveillance

Abstract In this study, we collected saliva and urine samples from individuals in the metropolitan region of Rio de Janeiro, Brazil, during the years of 2017 through 2019 and we were able to detect the presence of Chikungunya virus genome in these samples. Our findings reinforce the possibility to monitor Chikungunya virus circulation by analyzing saliva and urine from individuals during inter-epidemic periods.
