When you have tuberculosis, it is important to first clarify whether it is contagious, and if it is, roommates must be isolated and treated, and try not to go to crowded places. In addition, patients with tuberculosis should start regular anti-tuberculosis treatment as soon as possible once the diagnosis is clear. Currently, the combination of four drugs – isoniazid, rifampin, pyrazinamide, and ethambutol – is required for anti-tuberculosis treatment, which usually lasts 6-9 months, so roommates are advised to go to a TB specialist as soon as possible. In addition, patients with tuberculosis also need to strengthen nutritional support therapy, such as the intake of high-protein, high-nutrition food to enhance their resistance. In addition to this, patients need to rest more, avoid straining and stay up late.
