Causes and Risk Factors

Acute sinusitis is often the result of a viral upper respiratory tract, but allergens (substances that cause allergies) or pollutants may also be causes of acute sinusitis.
The bacteria responsible for acute sinusitis are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. These microorganisms, along with Staphylococcus aureus and anaerobic bacteria are responsible for chronic sinusitis.
Mushrooms lead to the occurrence of chronic sinusitis, especially in patients with diseases affecting the immune system (AIDS, leukemia, diabetes).
