data: overshoots in covid-attributed death count for Chile, Ecuador, Colombia #2795
Comments
Hi @czka, I just checked the source, and this seems to come from them. You can see this in their chars in the following links (scroll down once on their site):
I just contacted them to understand these values better. You can also contact them (more info at https://covid19.who.int/info, under the "Contact us" section). |
Hey @lucasrodes Thanks for clarifying and forwarding this to the source. I suppose an OWID team member will get a better reply from WHO than an average Internet being like me ;), so let's wait to see what they tell you. I'd love to know what others think, but for me it's surprising to see such huge, singular differences between Johns Hopkins University and WHO covid death counts, which are otherwise quite similar. Has OWID considered assessing those 2 data sources from the perspective of such annomalies? Because maybe there are more such cases besides those that I spotted (while updating my charts). |
Hi @czka, Before the source switch, we ran several tests comparing both sources to ensure no significant differences. Back then, we did not observe any of these singularities in these countries, which is aligned with what you say:
We are currently not making such comparisons, but I think that we should. I'll try to come up with some weekly JHU-WHO sanity checking so we can report any anomalies to the WHO. |
@lucasrodes Hello, it's been a while 👋🏿. |
Hi @czka, We reported the issues to the WHO, but we did not get any response. We are reporting values for confirmed deaths and cases as reported by the WHO, without any alterations. We do not plan on adding any processing on our side. We have reported this incident again to the WHO, but please feel free to report this yourself as you encounter new issues. |

Which data is inaccurate or missing?
Please refer to https://ourworldindata.org/explorers/coronavirus-data-explorer?facet=none&Metric=Confirmed+deaths&Interval=7-day+rolling+average&Relative+to+Population=false&Color+by+test+positivity=false&country=ECU~CHL~COL (screenshot attached).
On that chart, the covid death count for Chile around 22.03.2022 greatly exceeds the all-cause mortality in that period. Same thing for Ecuador around 21.07.2021 and 07.09.2020.
Aditionaly, I noticed 3 less severe, but still artifficially-looking spikes: Chile ~18.07.2020, Colombia ~09.05.2020, Ecuador ~13.01.2022.
Why do you think the data is inaccurate or missing?
As explained above.
Are these issues a matter of processing on the OWID's side, or do they originate from the WHO dataset you have switched to recently? As I compare with my charts rendered from the OWID's data before 08.03.2023, these spikes are something new.
