Tuberculosis is characterized by a low fever in the evening, mainly due to inflammatory changes in the lungs caused by infection with Mycobacterium tuberculosis, which leads to a series of symptoms. Tuberculosis fever is characterized as afternoon fever, which means that the patient will have a fever in the afternoon or evening and the temperature will drop to normal the next morning. In addition to the afternoon fever, tuberculosis also presents with cough, sputum, hemoptysis, loss of appetite, lethargy and weakness, and in many women of childbearing age, menstrual disorders. For pulmonary tuberculosis, positive sputum for antacid bacilli is the gold standard for the diagnosis of tuberculosis.
