Adapted from cdcfluview::who_nrevss.
This unexported helper function leverages the CDC FluView API to pull flu surveillance data collected from U.S. World Health Organization (WHO) Collaborating Laboratories and National Respiratory and Enteric Virus Surveillance System (NREVSS) laboratories. The data retrieved can be parameterized by geographic granularity and/or flu season. The function is used internally by get_cdc_clin.
Usage

national", "hhs", "census", or "state"- years
A vector of years to retrieve data for (i.e.
2014for 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 specify a 2-digit season value the function will convert that to the corresponding season identifier (i.e.57== 2017-2018).
