On his fascinating blog Random Analytics, Shane Granger takes an informed look at the new website of the Sierra Leone Ministry of Health and Sanitation: Ebola in Sierra Leone (to 31 Aug 2014). Click through for a knockout infographic and a table of cases by district. Excerpt:
The Ministry of Health and Sanitation for the Sierra Leone Government has recently updated its Situation Report (SITREP) on the Ebola Virus Disease (EVD) to the 31st August 2014. It is recommended viewing but here is an infographic of the situation, along with a data review for the Government of Sierra Leone for consideration (the latest update comes with a data anomaly) and a couple of laymen questions.
The Ebola in Sierra Leone (by District) infographic details the cases and fatalities from EVD including probable and suspected cases. Each District which is impacted by is listed with each figure representing 10x lives and then colour coded (see notes). The provisional CFR is based on total numbers and might not represent the Ministry of Health and Sanitation figures.
It should be noted that the outbreak is ongoing so these numbers are still very provisional.
The next is a table which highlights a very minor data anomaly (in red), which I will pass on immediately to the staff at the Ministry of Health and Sanitation.
Data anomaly aside, I hope that my small intrusion into their daily (and more important work that I am currently completing) adds some value. I know that the Ministry is under huge pressure and that their work truly does matter.
Final Thoughts, Predictions or Problems:
I’ve no problem with the data-cleansing itself anymore, outside of a small anomaly. The Sierra Leone government should be congratulated on its better presentation of the data, especially given its background story, low infrastructure prior to this new medical crisis and recent history in terms of civil war etc.
Yet I find some issues with the current data presented. I’m sure there are answers to these issues but there are questions that must be answered:
The Confirmed Fatality Rate for the most impacted regional Districts seems reasonable given the economic constraints of the country. I note the Districts of Kailahun and Kenema have a current total provisional CFR in the 40-percentile range. Yet, a couple of questions:
• The current CFR in Western Rural is 3.9% (yet including all cases is 57 including four deaths with a CFR of 7%; both totals seem a bit low; and:
• The big unexplainable for me is the CFR in Port Loko which the latest update currently states is just 2.9%. Given that when I last looked at the data (to 13 August) the CFR was 12% with 25-cases there has been either an anomaly with the data or a health deployment that I am not yet across.
