maybe tell them that whatever happens you'll be there for them (if u know them personally)
if u dont know them, it might be best to nit come in contact with them bc they might be scared. so wear a mask to put them at ease. (honestly masks dont help keep the virus out, but if someone is sick it helps contain it tho. it helps put ppl at ease tho)
if this didnt make sense or anything, just ask and maybe i can say more. like what specifically do u want to say? and to who?
maybe i can help put it to words better
