Ebola in the DRC. The Humanitarian Data Exchange has been tracking cases and deaths in the North Kivu Ebola outbreak. The numbers come from the Democratic Republic of the Congo’s health ministry and distinguish between suspected, probable, and confirmed cases; they are available at both the national level and disaggregated into the ministry’s 25 currently-affected health zones. Related: “Ebola cases pass 2,000 as crisis escalates” (Nature). Also related: The World Health Organization’s weekly situation reports. Previously: Data from the 2014 Ebola outbreak (DIP 2018.05.23).

ICE solitary confinement. The International Consortium of Investigative Journalists and partners have obtained records that detail 8,000+ instances, between 2012 and 2017, in which U.S. Immigration and Customs Enforcement detention centers placed detainees in solitary confinement. For each confinement, the records indicate the detainee’s citizenship, detention facility, dates of confinement, and the stated reasons for it. Note: “ICE said it does not keep records of every solitary confinement placement. Instead it tracks only those cases where detainees were held in isolation for more than 14 days, and where immigrants with a ‘special vulnerability’ were placed in isolation.” [h/t Jason Norwood-Young]
