Highest Detected Respiratory Pathogens

Respiratory pathogens tend to be seasonal, each one becoming widespread at roughly the same time each year. The period of higher influenza detections tends to overlap with high detections of other respiratory pathogens, making late fall and winter the traditional respiratory season.

Not all pathogens follow the same pattern, however, and the COVID-19 pandemic seems to have disrupted some typical respiratory patterns. BioFire® Syndromic Trends (Trend) offers a look at what respiratory pathogens are circulating throughout the year in the United States.
