I M P O R T A N T
=================

The CDC migrated to a new non-Flash portal and back-end APIs changed.
This is a complete reimagining of the package and — as such — all your
code is going to break. Please use GitHub issues to identify previous
API functionality you would like ported over. There’s a [release
candidate for
0.5.2](https://github.com/hrbrmstr/cdcfluview/releases/tag/v0.5.2) which
uses the old API but it likely to break in the near future given the
changes to the hidden API. You can do what with
`devtools::install_github("hrbrmstr/cdcfluview", ref="58c172b")`.

All folks providing feedback, code or suggestions will be added to the
DESCRIPTION file. Please include how you would prefer to be cited in any
issues you file.

If there’s a particular data set from
<https://www.cdc.gov/flu/weekly/fluviewinteractive.htm> that you want
and that isn’t in the package, please file it as an issue and be as
specific as you can (screen shot if possible).

Retrieve U.S. Flu Season Data from the CDC FluView Portal

Description
-----------

The U.S. Centers for Disease Control (CDC) maintains a portal
<http://gis.cdc.gov/grasp/fluview/fluportaldashboard.html> for accessing
state, regional and national influenza statistics as well as Mortality
Surveillance Data. The Flash interface makes it difficult and
time-consuming to select and retrieve influenza data. This package
provides functions to access the data provided by the portal’s
underlying API.

What’s Inside The Tin
---------------------

The following functions are implemented:

-   `agd_ipt`: Age Group Distribution of Influenza Positive Tests
    Reported by Public Health Laboratories
-   `cdcfluview`: Tools to Work with the ‘CDC’ ‘FluView’ ‘API’
-   `cdc_coverage_map`: Retrieve CDC U.S. Coverage Map
-   `geographic_spread`: State and Territorial Epidemiologists Reports
    of Geographic Spread of Influenza
-   `hospitalizations`: Laboratory-Confirmed Influenza Hospitalizations
-   `ilinet`: Retrieve ILINet Surveillance Data
-   `ili_weekly_activity_indicators`: Retrieve weekly state-level ILI
    indicators per-state for a given season
-   `pi_mortality`: Pneumonia and Influenza Mortality Surveillance
-   `state_data_providers`: Retrieve metadat about U.S. State CDC
    Provider Data
-   `surveillance_areas`: Retrieve a list of valid sub-regions for each
    surveillance area.
-   `who_nrevss`: Retrieve WHO/NREVSS Surveillance Data

The following data sets are included:

-   `hhs_regions` HHS Region Table (a data frame with 59 rows and 4
    variables)
-   `census_regions` Census Region Table (a data frame with 51 rows and
    2 variables)

Installation
------------

``` r
devtools::install_github("hrbrmstr/cdcfluview")
```

Usage
-----
