We have gone past the 400 mark. The ‘Life threatening for the ill and elderly ( and also possibly those who has chronic asthma)’ range.
One issue of concern is that N95 masks are hard to get everywhere.
I empathise for those walking outside on the streets now. They must be breathing in hellfire. Mask or no mask. I can’t see five metres out from my window.
I just hope it doesn’t get any higher and that the rains will come soon.
