Important Note on Meaning

The word "lassa" has two distinct and unrelated meanings: 1. A severe infectious disease named after the town of Lassa in Nigeria, where it was first documented. 2. An archaic spelling for Lhasa, the capital of Tibet. In modern English, the spelling Lhasa is almost universally used for the city. When encountering "lassa," context is crucial to determine whether it refers to the disease or the historical name for the Tibetan city.

Noun
