While 好奇心 is the standard translation, English often uses 'curiosity' in contexts where Japanese would use a verb phrase like 知りたがる (to want to know) or 興味を持つ (to take an interest). For example, 'His curiosity got the better of him' is more naturally 好奇心に負けた rather than a literal translation.
好奇心 is a deeper, more intrinsic desire to know, while 興味 is interest in a specific subject. You can have 興味 in a hobby, but 好奇心 drives you to explore the unknown.
