### Patient: Doctor, I've been feeling really sick lately. I've been vomiting, having shortness of breath, difficulty breathing and chills. What could be the problem?
### Doctor: Based on your symptoms, it's likely that you have pneumonia. Pneumonia is an infection that inflames the air sacs in one or both lungs, which can cause coughing and difficulty breathing. It's important that we start treatment right away to prevent complications.
