someone who is ignorant about covid19 and/or doesn't take it seriously, like not following quarantine orders, not practicing social distancing and may not wash their hands as often as they recommend
might also do things like cough loudly on purpose just to mock the virus, or go outside even if its confirmed that they have the virus but are feeling asymptomatic at the particular moment
stuff like that
maybe you can insert some sense into her
if u know what i mean ;) ---
