感染

• Pinyin: gǎn rǎn
• Hanzi breakdown: 感 = 咸 + 心 (feel, touch); 染 = 氵 + 九 + 木 (dye, infect — a dyeing process)

Meaning

To infect; to be infected (medically); to move or influence someone emotionally (figuratively).

Has two primary uses: (1) Medical — pathogen transmission, e.g. 细菌感染 (bacterial infection). (2) Emotional/artistic — the power to move an audience or inspire others, e.g. 她的热情感染了所有人 (her enthusiasm influenced everyone). Both uses are common in modern Chinese.
