I make a point of wearing a mask when I have a sniffle and still working - and as part of the #WellKiwi study I often know which non covid bug I have - but amazes me in the places I work the numbers of coughs and sniffles in tightly packed poorly ventilated office spaces. I might be wearing as a courtesy - but certainly reduces the #hayfever and respiratory issues from dust and particulates - even in “clean green” #Wellington - so far I mostly catch the bugs the youngest brings home from school.
