the health department does contact you but their concern is not the day of exposure. If you test positive, your quarantine is 10 days from the day of first symptoms. You then file a report daily to give your symptoms with them through your phone or computer. If at the end of your 10 days you are fever free for more than 24 hours without the help of fever reducing medications, you will be given clearance to go back to work. Your family’s quarantine is 14 days from that last day of your quarantine as it may take that long for them to show symptoms.
