🖐👟👄 Disease.. Please read and help!

My 1.5 year old DS has hand foot mouth disease. I've stayed home from work the past two days and have been up all night with him the last two nights. All he wants is mama. His slobber, etc. has gotten all over me. I'm almost 22 weeks pregnant. I know I'm at an elevated risk of catching this but there is nothing I can do. I have to take care of my sick baby. Anyone with experience on this? If I get it, what happens? Just reading a lot of mixed articles. The ER dr said to keep sanitizing but understands you can't just have a little boy fend for himself. I'm just worried Bc he's been attached to me all day and night. He doesn't want my husband at all. Any similar experiences people can share would be much appreciated. Thank you!
