Diagnostic criteria for pneumonia of unknown origin

The diagnostic criteria for pneumonia of unknown origin are strict, other causes should be excluded, pathogens should be identified through symptoms and examinations, symptomatic support and treatment should be taken, changes in disease conditions should be closely monitored, and medical observation should be carried out for close contacts. According to the diagnostic criteria for pneumonia of unknown origin, the following is a serious medical original compilation. 1. Pneumonia of unknown origin is a potentially infectious disease that requires strict diagnostic measures. 2. Diagnostic criteria mainly include the following: fever: temperature above 38 ° C.

Other known causes such as bacterial, viral, fungal, mycoplasma infections, and other non-infectious diseases are excluded. 3. For patients with pneumonia of unknown cause, detailed history collection, physical examination, and laboratory tests are required to determine the cause. 4. Laboratory examination includes blood routine, C-reactive protein, procalcitonin, serological examination, etc., which is helpful to judge the pathogen of infection. 5. Pathological examination: nucleic acid detection, virus isolation culture, drug sensitivity test, etc., which is of great significance for identifying pathogens. 6. Chest imaging examination: X-ray or CT examination is very important for evaluating the scope and degree of lung lesions. 7. In the diagnosis process, it is necessary to pay attention to exclude other similar diseases, such as tuberculosis, lung cancer, heart failure, etc. 8. For patients highly suspected of pneumonia of unknown origin, they should be admitted to isolation wards in time and protective measures should be taken to prevent cross infection. 9.

Closely monitor the patient's condition changes and adjust the treatment plan in time. 11. Close contacts with pneumonia of unknown origin should be medically observed. If there are symptoms, seek medical attention in time. Key information: Pneumonia of unknown origin should be diagnosed strictly according to diagnostic criteria, including fever, respiratory symptoms, lung imaging changes, etc., and other possible causes should be ruled out. Laboratory tests and etiological tests are important to identify pathogens. Treatment mainly includes symptomatic supportive treatment and etiological treatment, and close monitoring of disease changes. Close contacts should be medically observed. The above contents are for reference only. Specific diagnosis and treatment should be carried out under the guidance of doctors. In the face of pneumonia of unknown cause, vigilance should be maintained, medical treatment should be sought in time, and appropriate protective measures should be taken to protect the health of oneself and others.
