Hi all:


With the new variant of SARS-Cov-2 being more "infectious" either by higher
viral load in the droplet or easier to enter the cell, should we, under the
Precautionary Principle, recommend/advocate the use of higher level of
respiratory protection ( i.e. N95)?

Subject: [MCOH-EH] Assessment of contacts post vaccination,


My understanding is that individuals after vaccination need to follow the
same public health guidance as non-vaccinated individuals.   Although the
vaccine is 95% effective in limiting symptomatic disease,  it is not known
to what extent it decreases the risk of asymptomatic disease or
transmission.   For those reasons a fully vaccinated HCW who was a COVID
contact should still be furloughed from work.  Is anyone doing anything
