There are 16 different types of hemagglutinin (H) proteins and nine different types of neuraminidase (N) proteins. This is how names such as H1N1 or H3N2 are acquired. However, the pandemic H1N1 influenza is different because it was created from a combination of human, swine and bird flu viruses.
Last name: Butte. This interesting surname of English origin with variant spellings But, Butt, Butte, Bute, etc., is derived from the middle English personal name But(t) of unknown origin, perhaps originally a nickname meaning short and stocky and akin to the late middle English butt meaning thick end or stump.
Among the well-known non-flat-topped buttes in the United States are Bear Butte, South Dakota, and Black Butte, Oregon. In many cases, buttes have been given other names that do not use the word butte, for example, Courthouse Rock, Nebraska. Also, some large hills that are technically not buttes have names using the word butte, examples of which are Kamiak Butte and Chelan Butte in Washington State.
