Persistent runny nose after recovering from COVID-19

COVID-19 refers to infection with the novel coronavirus. Persistent runny nose after recovery from a novel coronavirus infection may be a normal phenomenon, or it could be caused by conditions such as rhinitis or influenza. Appropriate treatment measures can be taken based on the underlying cause.

I. Physiological Phenomenon

After recovering from a novel coronavirus infection, the virus in the body has gradually been eliminated. However, the virus may still affect the upper respiratory tract, making runny nose more likely. This is considered a normal physiological response, possibly due to incomplete recovery of the body. No special treatment is required—adequate rest is usually sufficient.

II. Pathological Phenomena

1. Rhinitis

The individual may already have rhinitis. After contracting the novel coronavirus, local mucosal tissues may become irritated, triggering an episode of rhinitis. If symptoms are mild, follow medical advice to rinse the nasal cavity with saline solution. When necessary, medications such as cetirizine hydrochloride capsules or budesonide nasal spray may be used.

2. Influenza

After recovery, the immune system may not yet be fully restored. During this period, catching a chill or being infected by another virus may trigger influenza. Antiviral medications such as oseltamivir granules or zanamivir inhalation powder can be used for treatment.

In addition, chronic sinusitis could also be a possible cause. If symptoms persist, it is recommended to seek timely medical evaluation at a hospital to determine the exact cause and receive targeted treatment.
