The CDC FluView application uses a composite basemaps of coverage areas
within the United States that elides and scales Alaska, Hawaii,
Puerto Rico &amp; the Virgin Islands and some further provide elided and scaled
breakouts for New York City and the District of Columbia.This function retrieves the given shapefile, projects to EPSG:5069 and
returns it as an <code>sf</code> (simple features) object.

The 'U.S.' Centers for Disease Control and Prevention (CDC) maintain
a portal <https://gis.cdc.gov/grasp/fluview/fluportaldashboard.html> for
accessing state, regional and national influenza statistics as well as
mortality surveillance data. The web interface makes it difficult and
time-consuming to select and retrieve influenza data. Tools are provided
to access the data provided by the portal's underlying 'API'.
