A long cough is not necessarily tuberculosis. If so, there will be repeated low-grade fever, sweating and emaciation, which may be pharyngitis or bronchitis caused by a cold. It is recommended to drink more warm water, don't stay up late, have a light diet and don't eat spicy, stimulating and cold food. You can eat some fruits with sore throat, such as pears, passion fruit and pitaya. And you can also drink boiled loquat leaves and eat stewed rock sugar in Sydney.
