For people with chronic obstructive pulmonary disease (COPD), fever is often linked to some kind of virus or infection in the respiratory system, such as:

Acute bronchitis
Flu
Pneumonia
Any intermittent or high-grade fever should ring alarms for lung infection. Visiting your doctor is always the best way forward to prevent further deterioration of health.
