An 8-year-old daughter experienced three episodes of high fever within the first 15 days, followed by coughing and vomiting after drinking milk. As the parent was busy with work, the grandmother, who didn’t understand Mandarin, took her to the hospital for intravenous fluid therapy and she seemed to improve, so they didn’t seek further medical attention. However, a few days later, she started coughing again. Last week, the child was absent from school for a week for X-rays and mycoplasma culture, no issues were found, but there were some thickened lung textures, and she was diagnosed with bronchial pneumonia. After 6 days of intravenous treatment, she stopped coughing but started coughing again a few days later, causing great disappointment.
