In an ordinary residential complex in Feng City.
Song Zhifang was anxiously keeping watch by her son's bedside.
Her son, Wang Xingguang, who had just started second grade, had caught the flu at school the day before, joining the countless others who had fallen ill.
Having dealt with her son's illnesses so often, Song Zhifang felt she'd practically become a doctor herself. When it came to common colds and fevers, she had her own "tried-and-true" methods.
First, she gave her son children's ibuprofen to bring down the fever, followed by a pediatric cold and flu granule to alleviate his symptoms.
Lastly, worried about a possible infection, she gave him some amoxicillin.
This three-pronged approach of a fever reducer, a cold remedy, and an antibiotic seemed remarkably effective.
Wang Xingguang's high fever broke that same evening.
However, the fever was gone.
A new problem, though, had emerged.
His upper respiratory infection seemed to have worsened.
