Hi Everyone, I'm new here. I've been doing a search about climate/altitude and sickness such as ear infections and sinus infections.

The problem is my 10 month old grandson lives in Michigan and I live in Pennsylvania and when his parents visit it seems that the baby ends up sick with fever, runny nose, sinus & ear infections, does anyone know can this be caused from the change going through the mountains, the climate, altitude etc?

He has tubes in his ears and we thought that would help but he was just here last week and with in a day he was running a high fever, runny nose and crying constantly as if he were in pain. It breaks my heart to see him this way. 2 different emergency rooms, One said ear and sinus infection the other said a virus.

Any knowledge on this? Thank you for reading this.
