Hong Kong has entered the peak of the winter flu season, placing patients with chronic obstructive pulmonary disease (COPD) at heightened risk of infections and acute exacerbations. Respiratory specialists warn that once a COPD exacerbation occurs, lung function can decline more rapidly, raising the likelihood of hospitalisation and death while adding pressure on the healthcare system. Early stabilisation and personalised disease management are therefore critical for both patient outcomes and system resilience.
