Please read- 4 month old diagnosed with bronchitis

Cassie

So my little one started having a runny nose and wet cough three days ago. At first I chalked it up to allergies as pollen has been flying in the south now that it’s warmed up. But cough started to get worse so I called pediatrician and they sent me to the ER.

Well she was negative for RSV, and the flu. Based off her xrays dr said no pneumonia but that she had the early stages of bronchitis. Because she doesn’t have a fever or labored breathing they won’t test for COVID 19.

Any medical professionals on here? Can COVID 19 cause bronchitis? Ive heard about pneumonia but haven’t heard anything about bronchitis. Please help. Worried about my little one
