Parents don’t have to rush to take their children to the hospital when they hear of a cough, because many colds can be cured with careful care at home, except for the following five. 1. Dry cough at night: If your child has a constant cough that gets worse at night, parents should be careful. This may be a symptom of asthma. At this point, the child should be taken to the doctor, and if they appear unable to eat, drink or speak with difficulty, it is best to call an emergency vehicle. 2. Cough with abnormal sound when breathing: If the child has had a cold for several days and the coughing sound has changed somewhat, with a hissing sound and breathing that seems rapid and very temperamental, it may be caused by bronchitis. You can take him to the doctor, and at the same time, you should encourage your child to rest more, drink juice, and in serious cases, you may need oxygen. 3. Coughing with a ho-ho sound: Your child has coughing symptoms a week after catching a cold. Sometimes, he or she will cough more than 20 times in one breath and make a ho-ho sound when inhaling. This is a symptom of bacterial infection, and there may be phlegm or even lumps blocking the airway, requiring immediate hospitalization and observation for infants under 6 months of age. 4. Cough with a lot of phlegm that affects breathing: A week after the child has caught a cold, the situation has not improved, and the cough has become a lot of phlegm, and breathing is faster than usual. This is likely to be a symptom of pneumonia, and the child should be sent to the hospital for an X-ray, and antibiotics should be used. Generally speaking, pneumonia can be taken care of at home, but severe cases require hospitalization. 5. Fever accompanied by cough: The child has a high fever, along with a weak, hoarse cough, body aches and a runny nose. This symptom is usually influenza. The child should be allowed to eat as much fruit as possible, and fever-reducing medicine can be taken over 6 months of age. If the fever still persists, the child needs to seek medical attention as soon as possible.
