More direct access to ESR database about nz-covid19-data HOT 8 OPEN

Here's my script to extract a CSV of cases by DHB over time from that ESR shiny app - https://github.com/UoA-eResearch/nz-covid19-data-auto/blob/master/fetch_ESR.py

from nz-covid19-data.

Hi @simeonmiteff

I have been playing with both the ESR data and the spreadsheets - on Friday the Ministry missed 4 cases from their update - so I filled them in from the ESR data - but today the Ministry's update came through before the ESR one. So it seems that neither one is better - also I am relying on the overseas/nz/unknown case origin classifications which are not in the ESR data ...

Some more inferences:

The authoritative database is presumably "ESR EpiSurv", which looks to be a SharePoint system.

Here is the form that case information is being captured with: https://surv.esr.cri.nz/episurv/CaseReportForms/Field_Coronavirus_Mar2020.pdf

I believe that partially overlapping subsets of the fields seen in that form get exported from SharePoint to (at least) two different spreadsheets:

• One that is sent to MOH where it is published on the website, along with someone copying new case rows from the sheet into a CMS for the HTML tables (while their exercising creativity by subtly changing the format almost every day).

• One that is uploaded to arcgis.com to drive the geospatial dashboard.

I imagine that cases imported between the times that the two spreadsheets are exported is the cause of your two missing cases.

I've also been looking into this EpiSurv system, you can find it's details here (however the system itself requires a username/password to gain access):

I do note that the media outlet thebfd.co.nz claims to be getting data from a direct extract from this system, so possibly it's available to people outside the medical field as well:

My understanding is you are correct - everything (that the Ministry holds) sits in EpiSurv and the releases are just extracts from it.

I think the bfd is just mirroring exactly what is on the Ministry of Health update page e.g. https://www.health.govt.nz/our-work/diseases-and-conditions/covid-19-novel-coronavirus/covid-19-current-situation/covid-19-current-cases#lab

from nz-covid19-data.

Here's a more useful screenshot with the EpiSurv extract details

Ah you are right, they are just copy and pasting from the dumps on health.govt.nz.

Interestingly when I was doing sleuthing on google thebfd was showing up for my search term but not health.govt.nz.

I guess the elusive true source of this data is out of reach for us non-medical folks.

Okay so I've found another data source out of ESR:

https://nzcoviddashboard.esr.cri.nz/

This one seems to use a streaming API based around rstudio's shiny-server. I am not an expert in this kind of streaming API but if you find someone who is it might be a helpful data source. I have not analysed if this is any more up to date than the other sources of data.
