cord-356316-ui11jr2h	Patel, Monita R	Performance of oropharyngeal swab testing compared to nasopharyngeal swab testing for diagnosis of COVID-19 —United States, January-February 2020	2020-06-16		.txt	text/plain	1181	88	62	Among 146 nasopharyngeal (NP) and oropharyngeal (OP) swab pairs collected ≤7 days since illness onset, CDC real-time RT-PCR SARS-CoV-2 assay diagnostic results were 95.2% concordant. Current US Centers for Disease Control and Prevention (CDC) guidelines identify nasopharyngeal (NP) and oropharyngeal (OP) swabs as acceptable upper respiratory specimens to test for presence of SARS-CoV-2 ribonucleic acid (RNA) (1) . Overall, among persons with specimens collected early in the illness course, SARS-CoV-2 RNA diagnostic results were highly concordant between OP and NP swabs. Current Infectious Diseases Society of America Guidelines specifically recommend collection of NP, mid-turbinate or nasal swabs rather than OP swabs alone for all symptomatic persons; our findings suggest this recommendation may be particularly relevant for persons later in the illness course and who may have lower amount of SARS-CoV-2 viral RNA (7). Together, our findings support CDC guidelines that identify NP and OP swabs as acceptable specimens for SARS-CoV-2 RNA testing; but suggest that NP swab may comparatively be a more sensitive specimen type for testing persons later in the illness course.	./cache/cord-356316-ui11jr2h.txt	./txt/cord-356316-ui11jr2h.txt
