1/ This is big— Germany now mandating medical grade masks for all citizens in public transport & in supermarkets (last week only done in Bavaria region, which is even stricter- only FFP2 masks)
Germany is calling for FFP2, N95, KN95 or surgical masks
2/ “Meanwhile in France, the country’s health advisory council on Monday discouraged the wearing of inefficient cloth and homemade masks, also arguing they may not offer sufficient protection against the more highly transmissible coronavirus variants.”
3/ “The new European recommendations follow increases in supply since the early days of the pandemic, when there were concerns that the use of medical masks by the public would mean there would not be enough for front-line medical workers.”
Read that again. ⬆️ SUPPLY
4/ “If the virus becomes more dangerous, the mask has to get better,” Söder said
While the virus is not more virulent now (as far as we know), a more transmissible variant is spreading - #B117– & that is more dangerous. It can more quickly overwhelm our hospital systems #covid19
Remember that the Korean government literally bought 80% of the nation’s KF94 masks (N95 equivalent) & shipped them to pharmacies at a discounted price to make sure the general public had access to #BetterMasks— in MARCH 2020.
2/ “As Koreans learned of the scale and aggressiveness of #Covid19, first from Chinese reports, then from a surge of cases at home, the mask with the weave and construction that proved most effective against the virus could not be found, except at exorbitant prices online.”
1/ Just as #B117#covid19 variant is spreading more effectively, so too do each of our interventions have to be that much more effective
•masks— need better source control & personal protection
•testing— scaled up + smarter use of rapid antigen tests for control
2/
•Tracing— needs to be much faster; digital tracing was used in other countries, NY & others tried an opt in system via apps, unclear how that did
•Isolating — other countries used isolation spaces outside of the home- our efforts here started but didn’t seem to pick up
3/ •vaccines— we know this effort has been very inefficient; many others have opined strategies for how to improve
•quarantine— similar to isolation above; need masks at home, need paid time off for folks; otherwise, people will do what they need to survive/ put food on table
Short🧵 1/
So @CDCgov on their “Your Guide to Masks” has a section saying don’t use N95s or surgical masks for the general public bc they are reserved for healthcare workers. That is their reason. They invoke a *shortage of supply* as their main rationale cdc.gov/coronavirus/20…
2/ On a separate page, they talk about the presumption that most transmission of #covid19 is happening via droplets but in *special circumstances* transmission happens via aerosols as well
