Haze issue

Mommies, with the haze, other than trying to stay indoor, how do you keep yourself in healthy state? Apparently I got sick cause of the haze and I’m already at 37weeks. On top of that, how do you protect your newborn from it? (I don’t think the haze will go away anytime soon) and how about when times you need to bring baby go out? (Like injection, etc)
