Overview
COVID-19 primarily affects the respiratory system, and lung symptoms are a major concern. The virus can cause inflammation, fluid buildup, and scarring in the lungs.
Symptoms
Shortness of breath, cough (often dry), chest pain, and difficulty taking deep breaths.
Causes
The virus enters the lungs and causes inflammation and damage to the alveoli (air sacs), impairing the exchange of oxygen.
Treatment
Treatment includes supportive care, oxygen therapy, and medications to reduce inflammation. Severe cases require mechanical ventilation.
When to See a Doctor
Any difficulty breathing or persistent cough should be evaluated by a doctor.
