An examination
1. Peripheral blood test
The total number of white blood cells is generally not high or decreased, and lymphocytes are increased. Severe cases can also be elevated. If combined with bacterial infection, the total number of white blood cells and neutrophils rise.
2. Blood biochemical examination
In some cases, hypokalemia occurred, and in a few cases, creatine kinase, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, and creatinine were elevated.
3. Pathogen related examination
It mainly includes virus isolation, viral antigen, nucleic acid and antibody detection. Virus isolation is the primary method of laboratory testing; viral antigen and nucleic acid detection can be used for early diagnosis; antibody testing can be used for retrospective investigation, but it is of little significance for early diagnosis of cases.
4. Imaging examination
Some patients may present with signs of bronchial infection with increased bronchial texture. In severe cases, pulmonary invasive lesions or pleural effusion may occur, or even fused into a piece.
