If you’re handling someone’s laundry who is or has recently been ill, make sure you immediately wash your hands when you’re finished and don’t touch your face until you have. You should also be careful not to throw their laundry around too much as there’s a chance bacteria particles could be spread through the air. Their laundry can also be washed with other people’s in the household and on a 60 degree heat is fine.
