使用说明
Kansen is a versatile word used for medical, digital (computers), and social (emotions/habits) contexts. It is frequently turned into a verb by adding 'suru'.
常见错误
Learners often use 'kansen' for general pollution (like air pollution), but 'ousen' should be used instead. Also, remember to use the particle 'ni' for the source (e.g., virus ni kansen suru).
记忆技巧

词源
