## TL;DR

Enhanced surveillance in Panama detected Oropouche and Punta Toro viruses before a major outbreak, showing the need for broader arbovirus testing.

## Contribution

Early detection of Oropouche virus and identification of Punta Toro virus through expanded surveillance in Panama.

## Key findings

- Oropouche virus was detected 5 months before the 2025 national outbreak.
- An additional case of Punta Toro virus was identified through contact tracing.

## Abstract

Enhanced arboviral surveillance in Panama revealed an Oropouche virus case, 5 months before the 2025 national outbreak, in samples that tested negative for routinely screened arboviruses. Subsequent contact tracing identified an additional case of Punta Toro virus. Our findings highlight the importance of expanding diagnostic efforts to identify circulating arboviruses.
