Just got home from 32-week growth scan to see that a parcel had been delivered and left with a neighbour while we were out. I saw the parcel outsude neighbours front door (we're in flats). So I knocked on the door to check he didnt mind it waiting there till DH gets home (it's furniture so I can't carry it up the stairs). Anyway, this elderly gentleman looked very unwell so I asked if he was ok and he informed me he was recovering from what doctors think is pneumonia. I was chatting to him for 5-10 mins and made my way upstairs when it dawned on me that pneumonia might be contagious. Do I need to be worried?
