Husbands co-worker came to work with civid

So yes I'm pretty hot. My husband Is a diesel mechanic and for a week his co worker came to work with covid. This guy's son recently tested positive and is in the hospital on the ventilator and the guy's wife was positive too and this dumb ass came to work with covid and told them TODAY he tested positive. Now my husband is at the doctor getting tested and I'm scared because we have a 10 month old at home and hes exposed us and others as well. Now I will ne worried for 2 weeks and praying that my baby will be protected from this because one IDIOT decided to come to work with covid
