Respiratory infections are climbing together in Taiwan with the start of term. Taichung has been flagged as possibly entering flu epidemic conditions next week, while Covid-related consultations are counted as 2.6 times higher.

A rise in infections just after term begins is an annual pattern. Children and adolescents dispersed over the holidays regather in the dense space of a classroom, and transmission opportunities increase sharply.

What marks this episode is the overlap of three. When influenza, Covid-19 and other respiratory infections rise together, symptoms alone are hard to distinguish, and crowding at clinics lengthens waits.

The rule of thumb for families is simple. Where fever persists, breathing is difficult, or an underlying condition exists, it is advisable to seek care rather than judge at home.

Prevention returns to basics: hand washing, ventilating indoor spaces, and staying away from school or work when symptomatic. Guidance on flu vaccination usually begins around this time as well.

Korea shows a similar seasonal pattern. In schools, including overseas Chinese schools, the weeks after term begins are a period of higher absence, sometimes requiring adjustments to the academic calendar.

For parents the practical step is reading the school's notices. Thresholds for staying home and whether a medical certificate is required vary by school and district, so individual guidance is the accurate source.
