実験は同じ男性(一部マスクは4人)が強い声で“Stay healthy, people (皆さんお元気で)” と5回喋り測定。フリース素材は11番の首に巻くタイプをマスクに代用し逆に飛沫10%増加。フリース素材を通じて大きな飛沫を小さくさせた結果暫く滞留させたとの考察。12番のバンダナも半分��度しか減らない。

この研究(Harvard Grant Study)は457ページの本にまとめられ、その概要はThe American Journal of Psychiatry(アメリカ精神医学会の会誌)に掲載されてます。研究対象が男だけだが、長く観察された貴重な結果。
Amazing testing results! Abbott PanBio Rapid Antigen Test: ZERO false positives in 1575 symptomatics. 96% sensitive for patients Ct<32, and 100% sensitive for patients Ct<28 (most infectious). 50¢ to manufacture and $7 in Germany. Banned in USA.

We hear often about how delta is more transmissible, but we don't hear much about why that's the case or how that impacts exposure risk.
A new study by Li and colleagues is out on Virological that provides some insight:
NEW—Speed of testing is most critical factor in success of contact tracing strategies to slow

; a delay of 3 days or more between symptom onset & testing will not reduce onward transmission of virus sufficiently: a modelling study

The coronavirus spreads through airborne transmission, particularly indoors, and even beyond six feet, the CDC emphasized on Friday. The new guidance is a change from the agency’s previous position that most infections were through “close contact.”
NEW: Big expansion in mobile sites in NYC where you can get a covid test and, if needed, receive paxlovid pills *on the spot*. No cost, regardless of insurance or immigration status.
Now in all five boroughs. Locations and hours:
