Why do children often have recurring fevers during the Chinese New Year?

There may be several reasons for children experiencing recurrent fevers during the holiday season. During festivals, children may come into contact with more people and different environments, increasing their chances of bacterial or viral infections, especially respiratory illnesses. Changes in diet and daily routines—such as staying up late and irregular eating habits—can also affect a child's immune system, making them more susceptible to pathogens. In addition, some chronic or underlying medical conditions may flare up during the holidays, leading to repeated episodes of fever.
