February sees the transition from winter to spring, with temperatures remaining low and unstable. The period coincides with the Spring Festival, marked by increased travel, family visits, and gatherings, leading to higher population movement and a greater risk of disease spread.

  The Fengxian Center for Disease Control (FCDC) advises everyone to stay warm and vigilant against the concurrent spread of respiratory infections, Norovirus and other forms of infectious diarrhea, as well as non-occupational carbon monoxide poisoning.
