Executive summary

  • On 29 June, routine surveillance detected a confirmed case of EVD in Margibi County.
  • This is the first new confirmed case in the country since 20 March.
  • Four additional cases were confirmed in the following two weeks in Margibi and another one in Montserrado on the 12th of July.
  • All five cases have been in contact with the index case.


Data sources & extraction

  • The daily situation reports (SitReps) are generated by the Liberia Ministry of Health and Social Welfare (MoHSW) and are available on the MoHSW website.
  • Data were extracted automatically where possible and otherwise manually.
  • Basic data cleaning was performed.
  • All figures in this report are compiled up to the week ending 10 May 2015.
  • We would like to hear about your needs in order to create more specific figures and include them in future reports. Please get in touch with us at ebola_sitrep@lshtm.ac.uk.

Weekly new cases and deaths


  • Weekly number of new cases and deaths are computed by summing daily numbers. Note that this doesn’t account for reclassification of cases that occur over the week: as such, suspected cases that are confirmed will appear in both suspected and confirmed counts.
  • A week is defined from Monday to Sunday.
  • Weeks with missing daily SitReps appear slightly transparent.
  • Where possible, numbers are stacked by case status (confirmed, probable, suspected).

Cumulative cases and deaths


  • Cumulative number of cases and deaths are plotted with a daily time-step using all available SitReps.
  • Where possible, cumulative numbers are stacked by case status (confirmed, probable, suspected).
  • Cumulative numbers should increase over time. However, the figures show several drops, in particular around the end of October 2014.
  • This is due to continuous data cleaning and reclassification of cases status in the MoHSW line list.
  • Similar changes were reported in the WHO Sitrep of 29 October 2014.

Health-Care Workers


  • New and cumulative cases/deaths are available for health-care worker.
  • New cases/deaths seem incomplete as they sum to much less than their cumulative values.
  • Status (confirmed, probable, suspected) was not indicated in the SitRep until end of November.
  • Since December, only confirmed HCW cases are reported.
