Fever, malaise, loss of appetite, cough, sputum and hemoptysis.

Hazards

May spread to brain, subcutaneous, endocardium, etc., causing abscess.

Complications

Brain abscess, subcutaneous abscess, endocarditis, etc.

Examination

Blood routine, sputum and pus smear examination, bacterial culture, X-ray film, CT, pathologic examination, etc.

Diagnosis

Diagnosis is based on fever, malaise, loss of appetite, cough, etc., combined with blood routine, X-ray film, sputum and pus smear examination.

Treatment principle

Rich in vitamins, easy to digest, light food, avoid spicy and irritating food.

Etiology

Epidemiology
