Patients with pneumonia may experience sweating, which is clinically seen as a gradual increase in body temperature caused by specific pathogenic infections. At this time, the body sweats in order to balance the body temperature and lower it to the normal range in order to carry away the body heat and achieve a lower body temperature. It is commonly seen in hypothermia with a persistently elevated body temperature. It is common in pulmonary tuberculosis caused by Mycobacterium tuberculosis infection, and also in inflammatory reactions in the lungs caused by other specific pathogens, such as Staphylococcus aureus, Klebsiella, and Pseudomonas aeruginosa. Blood tests, CT of both lungs, and if necessary, lung secretions for pathogen culture and drug sensitivity tests can be taken to clarify the diagnosis and provide timely symptomatic and etiologic treatment.
