Chlamydia pneumoniae , a recently defined bacterium, is a common cause of respiratory tract infections in children and adults.
Congested nose is a frequently found symptom.
C. pneumoniae has been reported to be associated with asthma and with other chronic respiratory conditions. We have earlier reported an association with chronic pharyngitis and persistent otitis media with effusion. Patients seeking medical attention for symptoms such as longstanding nasal congestion, longstanding sore throat, aggregation of viscous mucus behind and in the throat, and tiredness are common in primary health care. We have investigated a group of twelve patients with persistent nasal congestion. Three of them were smokers.
