Rhinitis, runny nose, sniffles

A runny nose (rhinitis) is usually the symptom of a cold.


A runny nose (rhinitis) is usually the symptom of a cold. Chronic rhinitis can be caused by the persistent inflammation of the nasal mucosa. Allergic rhinitis is a seasonal condition (pollen) or caused by contact with other allergy triggers. Typical symptoms include nasal discharge (mucus) and a blocked nose. General hygiene measures (e.g. washing the hands) can have a preventive effect.
