Dry cough and prolonged low fever in the afternoon should be considered as tuberculosis, and it is recommended to consult a doctor in time for diagnosis, and receive anti-tuberculosis treatment as soon as tuberculosis is diagnosed. Dry cough and prolonged afternoon low fever are typical clinical symptoms of TB; individuals who go to the hospital and are found to have tuberculosis bacilli in their bodies should be actively treated. Combined use of anti-tuberculosis drugs is the main treatment for tuberculosis, so individuals should receive quadruple therapy, which is a combination of four anti-tuberculosis drugs, such as isoniazid, ethambutol, rifampicin, and pyrazinamide, as soon as possible after diagnosis of tuberculosis; however, the specific drug regimen needs to be formulated by a medical professional. Dry cough and prolonged afternoon low-grade fever are always present, not excluding the possibility of other diseases, such as interstitial pneumonitis, and rheumatoid immune-related diseases should also be noted. It is recommended that the patient consult a doctor in time to clarify the cause of the disease and treat the primary disease in order to effectively alleviate or eliminate all kinds of uncomfortable symptoms; therefore, if you have any abnormal discomfort, you should consult a doctor in time and do not delay.
