Causes Of Sinusitis

Respiratory Tract Infection

Upper respiratory tract infections that cause acute sinusitis are usually viral. Recent data indicated ninety to ninety-eight percent are caused by viruses, the most common of which are rhinoviruses, influenza viruses, and parainfluenza viruses. Other viruses, such as respiratory syncytial virus have been implicated in some cases. The most common bacteria implicated were Streptococcus pneumoniae, Haemophilus influenza, and Moraxella catarrhalis. Bacterial causes are now known to be behind only a few percents of cases. With this in mind, new guidelines have been established emphasizing more focus on treating the symptoms through natural methods, especially with increased bed rest for affected patients.
