In cdcfluview: Retrieve Flu Season Data from the United States Centers for Disease Control and Prevention ('CDC') 'FluView' Portal

Description

Uses the data source from the CDC FluView and provides flu reporting data as either a single data frame or a list of data frames (depending on whether either WHO NREVSS or ILINet (or both) is chosen.

Usage

get_flu_data(
  region = "hhs",
  sub_region = 1:10,
  data_source = "ilinet",
  years = as.numeric(format(Sys.Date(), "%Y"))
)

Arguments

region	one of "hhs", "census", "national", "state"
sub_region	depends on the region_type. For "national", the sub_region should be NA. For "hhs", should be a vector between 1:10. For "census", should be a vector between 1:9. For "state", should be a vector of state/territory names or "all".
data_source	either of "who" (for WHO NREVSS) or "ilinet" or "all" (for both)
years	a vector of years to retrieve data for (i.e. 2014 for CDC flu season 2014-2015). Default value is the current year and all years values should be > 1997

Details

A lookup table between HHS regions and their member states/territories is provided in hhs_regions.

Value

If only a single data_source is specified, then a single data.frame is returned, otherwise a named list with each data.frame is returned.

Note

There is often a noticeable delay when making the API request to the CDC. This is not due to a large download size, but the time it takes for their servers to crunch the data. Wrap the function call in httr::with_verbose if you would like to see what's going on.
