 ## Data curation
 
+UPDATE 2023-04-24: Following updates from the WHO, Global.health added 3 new probable cases to our line-list (ID# 41, 42, 43) to bring our total number of probable cases to 23 -- all probable cases have died. Global.health acknowledges differences in location data for probable cases between MINSABS and WHO reporting, as discussed in our 2023-04-19 update. We are unable to reconcile location data for probable cases at this time.

 UPDATE 2023-04-19: Confirmed case counts are updated from MINSABS and WHO reporting. Location data for the first 15 confirmed cases is consistent with MINSABS reporting through the [Epidemiological update on 2023-04-16]( https://www.guineasalud.org/archivos/Informes/Informe16042023.pdf) [n=15. Bata 9; Ebibeyin 3; Evinayong 2; Nsork 1]. Confirmed case number 16 was first added to our line-list using data from the [WHO Director-General media briefing](https://www.who.int/director-general/speeches/detail/who-director-general-s-opening-remarks-at-media-briefing-18-april-2023).
 
 Probable cases (n=20) are included in our line-list using data from [MINSABS Official Statement No. 3, Page 7]( https://www.guineasalud.org/archivos/Ordenes/Comunicado3.pdf). WHO reported an update on [2023-04-15](https://www.who.int/emergencies/disease-outbreak-news/item/2023-DON459) increasing the probable count to 23. Global.health is working to reconcile our case and location data; however, due to the presentation of aggregated data in official reporting, we may be unable to update or continue to track probable case data in our line-list moving forward.
