How to confirm whether it is coronary pneumonia

The diagnosis of novel coronavirus pneumonia needs to be comprehensively judged based on epidemiological history, clinical manifestations and laboratory test results. Among them, epidemiological history includes contact history with suspected or confirmed cases, recent travel history, etc.; The clinical manifestations mainly include fever, cough, fatigue and other symptoms; Laboratory tests include nucleic acid testing, antigen testing, routine blood tests, C-reactive protein, etc.

1. Epidemiological history:

1. Contact history with suspected or confirmed cases: If the patient has had close contact with the suspected or confirmed case before the onset of the disease, such as co-residents, colleagues, classmates, etc., it may be infected with the new coronavirus;

2. Recent travel history: If the patient has recently traveled to an area with a serious epidemic or traveled on business, he or she may also be infected with the new coronavirus;

3. Other conditions: If the patient has recently developed respiratory symptoms, accompanied by fever, fatigue, etc., it is also necessary to have a high suspicion of the possibility of new coronavirus infection.

2. Clinical manifestations:

1. Fever: Most patients will have fever symptoms, and the body temperature usually exceeds 37.5 °C and lasts for a long time.

2. Cough: due to inflammation irritating the airway mucosa, some patients will also have a dry cough, and a small number of patients may be accompanied by sputum;

3. Fatigue: Due to the decline of the body's immunity, it will also be accompanied by the phenomenon of general weakness.

3. Laboratory test results:

1. Nucleic acid testing: by collecting specimens such as nasopharyngeal swabs, oropharyngeal swabs and anal swabs of patients, and then extracting their nucleic acid components for testing, if the test result is positive, a preliminary diagnosis of novel coronavirus infection can be made;

2. Antigen detection: If the new coronavirus antigen detection kit is used for self-testing, when the T and C areas are observed to be colored at the same time, it generally indicates that the body may have been infected with the new coronavirus;

3. Blood routine: if the white blood cell count is normal or low, and the percentage of lymphocytes is reduced, the presence of new coronavirus infection is considered;

4. C-reactive protein: If C-reactive protein is significantly elevated, more than twice the upper limit of normal, it may also indicate the presence of novel coronavirus infection.

Chest imaging is also one of the important tools to assist diagnosis. Once the above uncomfortable symptoms appear, it is recommended to go to the respiratory medicine department of the hospital in time to improve the relevant examinations to clarify the specific situation.
