\title{Retrieve ILINet Surveillance Data}
ilinet(region = c("national", "hhs", "census", "state"), years = NULL)
5 years ago
\item{region}{one of "\code{national}", "\code{hhs}", "\code{census}", or "\code{state}"}
\item{years}{a vector of years to retrieve data for (i.e. \code{2014} for CDC
flu season 2014-2015). CDC has data for this API going back to 1997.
Default value (\code{NULL}) means retrieve \strong{all} years. NOTE: if you
happen to specify a 2-digit season value (i.e. \code{57} == 2017-2018)
the function is smart enough to retrieve by season ID vs convert that
to a year.}

The CDC FluView Portal provides in-season and past seasons' national, regional,
and state-level outpatient illness and viral surveillance data from both
ILINet (Influenza-like Illness Surveillance Network) and WHO/NREVSS
(National Respiratory and Enteric Virus Surveillance System).
This function retrieves current and historical ILINet surveillance data for
the identified region.
