What Is A Chest Infection If I Have A Chest Infection Could My Puppy Get It From Being Around Me?

If I have a chest infection could my puppy get it from being around me? - what is a chest infection

I have a severe lung infection and I coughed a lot, but my puppy wants to do 4 months, is curl up and sleep on my lap. I am very concerned that he might be near me. Can not find much on Google to owners about their illness, but nothing about the transmission of diseases from human to animal. Who knows, if I could spend my dog with pneumonia?
