The BioFire® RP2.1 Panel Did Not Identify Concurrent Respiratory Virus Infection in Adults with Variable SARS-CoV-2 Disease Severity and Infection Duration

Table 3

COVID-19 infection duration and concurrent respiratory infection.

					BioFire® testing
Infection length	# individuals		# NP samples		SARS-CoV-2 (+)		Other respiratory pathogens (+)
	Cohort 1 (n = 18)	Cohort 2 (n = 28)	Cohort 1 (n = 18)	Cohort 2 (n = 71)	Cohort 1	Cohort 2	Cohort 1	Cohort 2
Short	16	11	16	16	N/A ^2	14 (87.5%)	0 (0%)	0 (0%)
Long	2	5	2	17	N/A ^2	12 (70.6%)	0 (0%)	1 (5.9%)
Recrudescent	N/A ^1	12	—	38	—	26 (68.4%)	—	0 (0%)

¹Unable to determine potential recrudescent infections for cohort 1 due to limited sampling schedule. ²Selection criteria for what was considered a short or long infection were dependent on PCR ± status at the first visit.
