"Centers for Disease Control" in Kenya

[mubaldino]

Describe the bug
USGS gazetteer entries

To Reproduce
USGS entry for "CDC" or "Centers for Disease Control" is an exact match for that agency in Kenya.
The USGS entry for US "CDC" -- "Centers for Disease Control and Prevention" is spelled as singular "Center for Disease Control" and is not the complete name.

• incorrect match occurs and is coded as Kenya consistently.
• inadequate entries for USGS -- should fix with additional information sources.
