who_nrevss: Retrieve WHO/NREVSS Surveillance Data

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).

Usage

who_nrevss(region = c("national", "hhs", "census", "state"), years = NULL)

Arguments

region

one of "national", "hhs", "census", or "state"

years

a vector of years to retrieve data for (i.e. 2014 for CDC flu season 2014-2015). CDC has data for this API going back to 1997. Default value (NULL) means retrieve all years. NOTE: if you happen to specify a 2-digit season value (i.e. 57 == 2017-2018) the function is smart enough to retrieve by season ID vs convert that to a year.

Value

list of data frames identified by

• combined_prior_to_2015_16

• public_health_labs

• clinical_labs

Details

This function retrieves current and historical WHO/NREVSS surveillance data for the identified region.
