Main symptoms:
- Persistent cough, often with sputum
- Shortness of breath or wheezing
- Chest pain when breathing or coughing
- High fever and chills
- Extreme tiredness
Bluish coloration of the skin or lips (sign of poor oxygenation, in the most serious cases)

- A high fever (above 39°C) persisting for more than 3 days
- Severe difficulty breathing or wheezing
- Severe chest pain
- Coughing up blood

Â

- Blood test: For systemic check
- Oximetry: For oxygen levels in the blood check
Advice: Do not hesitate to consult a doctor for an accurate diagnosis.
What To Do In Case Of Infection
1. General Treatments
- Rest: Fundamental to recover energy.
- Hydration: Stay hydrated by drinking plenty of fluids to loosen mucus
