Whether it’s bacterial, viral—or the friendlier sounding “walking” pneumonia—chances are you or someone you know has had this illness at some point. The infection, which is caused by bacteria, viruses or fungi, can occur in one or both of the lungs. It can be mild or life-threatening, especially to the elderly, the very young or those with compromised immune systems.

There are more than 30 different types of pneumonia, and identifying the correct one isn’t always easy. At Yale Medicine, our physicians are experienced and skilled at treating everything from the most basic form of pneumonia to the more serious cases that might require hospitalization.

Researchers at Yale School of Medicine are studying how to better identify different types of pneumonia strains, so that the antibiotics given to patients are the best possible fit. “There has been a big push regarding antibiotics stewardship—how to treat patients appropriately with antibiotics, who needs antibiotics, and also what are some of the non-antibiotic alternatives to treat patients,” says Charles Dela Cruz, MD, a pulmonologist at Yale Medicine.
