Boyfriend and working

I’ve posted about this situation before but, my boyfriend and I live together, we’re expecting a baby within the next few weeks. He’s still been working until she comes seeing as how he’s considered an essential employee. He cleans and sterilizes in the operating rooms of a hospital. I’ve been self isolating at home for an entire month due to covid-19 and being pregnant. Literally the only places he goes are to the store when we need more groceries and to work.

I’m just curious to see what others say. Do you think his risk of exposure/contacting covid-19 and bringing it home where I am is high, being as he works in a hospital? He isn’t in direct patient care and doesn’t go in any room if a patient is in there.
