“Recovered from fever but still have congestion? Here's when it may be a risk”

Key points

• Fever may fade while respiratory symptoms persist for days after flu.
• Inflammation of nasal passages and respiratory tract can narrow airways.
• Persistent mucus drainage and bronchospasm can cause chest tightness and wheezing.
• Change in mucus colour to green/yellow may suggest secondary bacterial infection.
• Seek respiratory consultation if chest pain, worsening symptoms, or breathing difficulty occurs.
