10/18 Alert: 20211017 dataset files incomplete

8/18 Alert: QuarantineIsolation column in NightlyHousing is inaccurate
The QuarantineIsolation column in the NightlyHousing dataset is overreporting nights in quarantine and isolation. This bug has been extant since the creation of the QuarantineIsolation column. As a result, the NightlyHousing1 and 2 files have been removed from the server and will be replaced as soon as this issue is fixed.

8/17: Full / Incremental file pairs will be combined in this weekend's release
Release 2.0, scheduled for release on 8/23, will simplify dataset files by combining each _full and _incremental file pair into a single file, with the exception of NightlyHousing, which will remain two files due to its size. See Supplemental/General_dataset_features page for date range and file naming details.

8/3 Alert: Incorrect ResidentIds in NightlyHousing
The ResidentIds in the 202010801 version of NightlyHousing1 and NightlyHousing2 are incorrect -- different residents have the same ResidentId and ResidentId values do not match ResidentId values in other datasets. These files have been removed from the SFTP server and will be replaced with correct versions this coming weekend (Aug 7th or 8th, 2021).

=July 2021=

7/26: Release 1.49 deployed

Effective 6/21, the CovidTransmission files will be replaced by a single NightlyHousing file, wherein redundant information has been removed, HousingProgram has been added, and some text values are replaced with integer codes to reduce filesize. The folder name for this dataset will also be "NightlyHousing". See ResidentData/NightlyHousing for a full description of the dataset.

5/25: Alert: May 22/23 CovidTests files contain a semicolon in details string
Some strings in the Details column of May 22 and May 23, 2021 CovidTests files contain a semicolon, which will interfere with proper column separation when download. These files have therefore been removed from the SFTP server and will be replaced with corrected versions as soon as posible.

5/24: Typing cdcrdata.wiki will now get you to this wiki
Typing cdcrdata.wiki or www.cdcrdata.wiki in your web browser's address bar will now take you to the CDCR health care research archive wiki. No change was made to any other links and all your existing links will still work.

5/7 Alert: Missing records in CovidTransmission
Due to data entry errors in the source data, certain resident-days are missing from CovidTransmission even though the resident is present. These gaps occur most often for residents at NKSP and WSP, but are otherwise randomly distributed. A coding fix has been identified for this issue and we expect the gaps to be filled within the next two weeks. Check subsequent release notes for details on when this is fixed.

CovidLOC value simplified. See Releases for details.

3/21: Release 1.21 deployed
See Releases for details

3/16: Alert: Sequence value for "ViralTestResultDate" element of CovidInfection dataset is incorrect
The sequence value for "ViralTestResultDate" element of CovidInfection dataset is incorrect and will lead to incorrect matches if used to match with other test records. We anticipate correcting this issue by Monday, March 22. Using ResidentId+Sequence+Day will provide correct matches between ViralTestDate, ViralTestSpecimen, and ViralTestType elements. Please also note that until now, the description of the CovidInfection dataset did not clarify that for each element, only a maximum of one value is reported per resident per day. In cases of multiple tests collected on the same day, positive tests are chosen over negative tests.

3/15: Alert: Missing values in full version of demographics file
A number of demographic value categories including race, sex, ethnicity, and birthyear are missing from the full version of the demographics file. The are, however, in the incremental file. A corrected full demographics file is slated to be available by March 22. Details of the change will be provided in the release notes when deployed.

3/15: Release 1.2 deployed
