@zhang_yueting @EricTopol @loscharlos 2021. Lots of surgical masks and maybe cloth too. A couple of KF94/KN95 too.
I think any mask especially universal (so effective source control) plus good ventilation or outdoors and some behavior change (e.g. reduced and quiet talking) reduces viral load. https://t.co/zafyGIRiMW
@zhang_yueting @EricTopol @loscharlos 2021。很多外科口罩，也许还有布。还有几个 KF94/KN95。
我认为任何特别通用的口罩（如此有效的源头控制）加上良好的通风或户外以及一些行为改变（例如减少和安静说话）都会减少病毒载量。 https://t.co/zafyGIRiMW
