Question
If a child coughs again, it is likely due to weak immunity or viral infection. Severe coughing may lead to dry retching again. It is necessary to go to the hospital promptly for blood tests and imaging to determine the cause and receive nourishment. Generally, the condition will stabilize after one week of medication, but cough recurrence is common, so additional medication for a few days is needed to stabilize the condition.
Answer
During the flu peak season, the child was infected with the flu, experiencing high fever, coughing, and a runny nose. Although the fever has subsided and there is no more runny nose, the cough persists, especially at night. The child vomited from coughing yesterday. Based on the above description, the child may have coughed again due to weak immunity or viral infection, with severe coughing potentially causing vomiting. It is recommended that parents take their child to the hospital promptly for a blood test and imaging to determine the cause and receive nourishment. Typically, the condition will stabilize after one week of medication, but cough recurrence is a common occurrence, so additional medication for a few days is needed to stabilize the condition.
