No respirator is 100% safe?...CDC web sites...

Be alert to the infectious control in every ward. Mask printed on N95,99.
..SARS patients' /relatives' face did not..printed on 'SARS' .

-And resonable, analytic for this less than 0.1 micron
SARS virus. (<100 nm?) ?
-One gives you a pistol to fight like the thousands of
US army, can you use your own M16 machine gun? . esp. ICU staff...close
and
prolong contact....of droplets,etc..?

- No one knows what leads to the infectious contact,
over-stress of wearing mask only is adequate for close and prolong
droplets contact? Then why not all HK people wear mask(including
patients)
for 8 -10
hours per day for 7 days to exclude new infectious cases like >20 cases
daily from the buildings like Tai PO or hospitals? That is why fewer
people
would like to the restaurants,etc..? Mask down , virus comes? The same
measures to combat AIDS in the first beginning ? Mask and Goggle...to
escort
in the ambulance car....

Personal hygiene, good room ventilation, face / body
protection ..etc..are important ,too. Knowledge is
power. Be alert to the infectious control. Alert to the virus
concentration + distance + period of contact + personal equipment +
environment ..etc. Good luck.
