Development and validation of RT-LAMP for detecting yellow fever virus in non-human primates samples from Brazil.

ABSTRACT: Monitoring yellow fever in non-human primates (NHPs) is an early warning system for sylvatic yellow fever outbreaks, aiding in preventing human cases. However, current diagnostic tests for this disease, primarily relying on RT-qPCR, are complex and costly. Therefore, there is a critical need for simpler and more cost-effective methods to detect yellow fever virus (YFV) infection in NHPs, enabling early identification of viral circulation. In this study, an RT-LAMP assay for detecting YFV in NHP samples was developed and validated. Two sets of RT-LAMP primers targeting the YFV NS5 and E genes were designed and tested together with a third primer set to the NS1 locus using NHP tissue samples from Southern Brazil. The results were visualized by colorimetry and compared to the RT-qPCR test. St
