If TB is diagnosed, hospitalization is required for at least 2-3 weeks because the prognosis is good and curable with reasonable and regular anti-TB treatment. 2-3 weeks later, clinical symptoms will subside and infectiousness will disappear, so hospitalization is required for at least 2-3 weeks. After discharge from the hospital, you can continue anti-tuberculosis treatment at home. During home anti-tuberculosis treatment, you should also follow the principles of anti-tuberculosis treatment, that is, reasonable, regular, adequate and combined anti-tuberculosis medication, and the medication should be used under the supervision and guidance of doctors and family supervisors, and remedial measures should be taken if the medication is not used for any reason, so as to ensure regular medication, which can reduce the occurrence of drug resistance and eventually achieve sterilization and prevent and eliminate relapse. During home treatment, because TB is a wasting disease, it is important to increase nutrition in the diet and frequent indoor ventilation to avoid infecting others.
