Trevor, do we know how good the populace is at nasal swabbing themselves effectively?

Studies we and others have done show a loss of around 10-15% sensitivity with nasal swab v nasopharyngeal swab. Can get back towards 95% of NP sensitivity with saliva+nasal swab. That was with ~100 ppl and simultaneous collection of ea swab/saliva.

That sounds similar to our comparisons between nasal and NP as well. Interesting that saliva seems to help so much.

Saliva alone is better than NP. Pre-print should be up but medRxiv takes a while to scan human research protocols

curious it seems research has shown more virus in saliva for some time.. if so why did we start with uncomfortable NP swabs? I know our nurses have great variance in their collection techniques.. few hold for full 3s and twist 10s if they get deep enough.
