According to the local prevalence, there is no history of contact with pertussis patients. If the child has had fever, but the symptoms of cough after heat withdrawal are aggravated, especially in the evening, the cough is severe, and there is no obvious lung positive signs, it should be used as a suspected diagnosis. If there is obvious cough, the classification of white blood cells and lymphocytes in peripheral blood counts is significantly increased. According to these characteristics, the clinical diagnosis of pertussis can be made. In addition, bacterial culture positive or serological immunology, positive PCR test can confirm pertussis.

Differential diagnosis

Differential diagnosis of spastic cough:

1, paroxysmal cough: seizure refers to intermittent, there is no persistent state, paroxysmal cough is a description of the form of seizures, there is no cause, so there is no meaning, most of the episode cough is allergic cough.

2, persistent cough: cough is one of the most common symptoms in the respiratory system, is a protective measure of the human body, is beneficial to the body, when the respiratory mucosa is stimulated by foreign bodies, inflammation, secretions or allergic factors That is, it causes reflexive coughing, which helps to exclude foreign bodies or secretions that invade the respiratory tract from the outside, and eliminates respiratory tract stimulating factors. Persistent cough is a precursor to lung disease. This cough will take two to three months to heal once it starts, and any cough medicine seems to be powerless.

3. Allergic Cough: Allergic cough (AC) has not been recognized as an independent disease. The definition of it is still only in a descriptive stage, lacking a large number of systematic research observations. Mainly refers to some patients with clinical chronic cough, with some atopic factors, antihistamines and glucocorticoids are effective, but can not be diagnosed as asthma, allergic rhinitis or eosinophilic bronchitis (EB) It is not suitable for generalization to other diseases. This type of cough is defined as AC. Its relationship and similarities with allergic pharyngitis, EB, cough after a cold need to be further explored to determine whether it is an independent disease entity.
