Quidel COVID-19 and influenza testing data

This is a V3/V4 endpoint. As of September 22, 2026, the V3 and V4 APIs no longer receive new data. They still serve the historical data they already have, but current data is only added to the V5 API, accessed via the epidata_snapshot(), epidata_archive(), and epidata_meta() functions. For more details on the changes, refer to vignette("migration-guide"), and visit the V5 signals documentation to see which sources are currently available.
