be + catching

用法筆記

This adjective is used predicatively — it comes after a linking verb (be, become, stay, remain) — and is not placed directly before a noun. It is less formal and far less common than 'contagious' or 'infectious' in modern English. Many native speakers now find it slightly old-fashioned, though it is still understood. Typical subjects are common childhood illnesses (chickenpox, measles, flu) or skin conditions (rashes, spots).
