What causes sinobronchitis?

Viral Infection

- The majority of sinobronchitis cases are caused by viruses, such as:

- Influenza virus

- Parainfluenza virus

- Respiratory syncytial virus (RSV)

- Adenovirus

- Rhinovirus

- Coronavirus

Bacterial Infection

- Bacteria can cause sinobronchitis, especially in people with underlying medical conditions, such as:

- Streptococcus pneumoniae

- Haemophilus influenzae

- Moraxella catarrhalis

- Staphylococcus aureus

- Mycoplasma pneumoniae

- Chlamydophila pneumoniae

- Legionella pneumophila

Allergies and Irritants

- Allergies to substances, such as pollen, dust mites, pet dander, and mold, can cause the sinuses and airways to become inflamed, leading to sinobronchitis.

- Certain irritants, such as smoke, chemicals, and air pollution, can also cause sinobronchitis.

Risk Factors

Certain factors can increase the risk of developing sinobronchitis, such as:

- Cigarette smoking

- Exposure to secondhand smoke

- Chronic respiratory conditions, such as asthma, COPD, and cystic fibrosis

- Weakened immune system, such as from HIV infection, diabetes, or cancer treatment

- Seasonal changes

- Crowded living conditions

- Young age (children are more likely to develop sinobronchitis than adults)
