Question
A 2-year-old girl, who has previously been hospitalized for asthma and received treatment with azithromycin and asarone brain, suddenly developed a high fever of 39 degrees two days ago. After taking dexamethasone, her temperature dropped, but she continued to have a low-grade fever. Apart from the fever, she has no other symptoms. What could be the cause?
Answer
Low-grade fever in infants is often caused by viral infections, particularly throat infections, and usually does not present with systemic symptoms. Persistent low fever may require further examination to determine if it is caused by streptococcal or Staphylococcus aureus infection. It is recommended to conduct a throat secretion culture. If bacteria are found, a diagnosis can be made and appropriate treatment can be administered. Oral Qingkailing granules are a traditional Chinese medicine that can be tried, but it should be noted whether there is an effective response. If symptoms do not improve or worsen, medical attention should be sought promptly.
