COVID-19, tracheal hypersecretion, long-term symptom


Introduction: The typical clinical picture of COVID-19 is gradually becoming clearer, both in the acute phase and in the long-term. However, new symptoms are gradually being identified. We describe a long-term symptom that has not yet been reported.

Case description: A 49-year-old man consulted for persistent asthenia. The general practitioner found a fever (39.2°C), and COVID-19 was confirmed by the polymerase chain reaction test. Further symptoms appeared, notably thick, white, painless tracheal hypersecretion for 3 months before diminishing, without disappearing.

Conclusion: Non-inflammatory tracheal hypersecretion, not yet reported in COVID-19, may be an additional long-term symptom. The hyperstimulation of tracheal goblet cells secreting mucus is 1 pathophysiological hypothesis.
