Tuberculosis is a contagious disease, typically affecting the lungs, caused by the bacillus Koch. It is transmitted through the air during prolonged or repeated contact in poorly ventilated areas. Symptoms can include fever, persistent cough, fatigue, night sweats, and weight loss. While vaccination is recommended, it has not been mandatory in France since 2007. Cases in France have shown an upward trend in recent years, with the Île-de-France region being the most affected area.
