For Vancouver resident Farrell Eckman, having a long conversation or attending a workout class without breaking into coughs is a major accomplishment.

The 50-year-old is one of many people who researchers say developed pulmonary fibrosis — a condition that thickens the tissue in lungs and can affect breathing — after experiencing a severe case of COVID-19.

In January 2022, Eckman was admitted to Vancouver General Hospital because she was having trouble breathing along with flu-like symptoms.
