\title{Retrieve WHO/NREVSS Surveillance Data}
\usage{
who_nrevss(region = c("national", "hhs", "census", "state"))
}
\arguments{
\item{region}{one of "\code{national}", "\code{hhs}", "\code{census}", or "\code{state}"}
}
\value{
list of data frames identified by
\itemize{
\item \code{combined_prior_to_2015_16}
\item \code{public_health_labs}
\item \code{clinical_labs}
}
}
\description{
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).
}
\details{
This function retrieves current and historical WHO/NREVSS surveillance data for
the identified region.
}
\note{
HHS, Census and State data retrieval is not as "instantaneous" as their ILINet
counterparts.\cr\cr
Also, beginning for the 2015-16 season, reports from public health and clinical
laboratories are presented separately in the weekly influenza update. This is
the reason why a list of data frames is returned.
