The ongoing Ebola virus disease (EVD) outbreak in the North Kivu and Ituri provinces saw a stabilization in the number of new cases this past week, with 19 confirmed cases reported in the past week (23�29 October), essentially equivalent to the 20 confirmed cases the week before. The majority (63%) of newly confirmed cases link back to chains of transmission in Biakato Mine Health Area, Mandima Health Zone, including a further three cases detected outside of Mandima in individuals who recently travelled from Biakato.
Onward local transmission has been observed in a limited number of towns and villages within family/social networks or health centers where cases visited prior to their detection and admission to treatment. In Mabalako, seven new cases were reported, of which two were linked to Biakato, two reported local family contact, and two were contacts within local health facilities, suggesting possible nosocomial exposure; investigations are ongoing for the remaining case. In Mambasa Health Zone, one additional case was reported, linked to a large cluster of cases. In Butembo, after over 21 days with no cases, two were reported this week. Both were residents of Kalunguta Health Zone where they were likely exposed. Thus far, there is no evidence of onward transmission in Butembo; nonetheless, these events demonstrate the high risks of reintroduction and resurgence in previously cleared health zones.
During the past 21 days (from 9 � 29 October), 59 confirmed cases were reported from eight active health zones in North Kivu and Ituri provinces (Figure 2, Table 1) with the majority reported in three health zones: Mandima (49%, n=29), Mabalako (20%, n=12), and Mambasa (10%, n=6). As of 29 October, a total of 3269 EVD cases were reported, including 3152 confirmed and 117 probable cases, of which 2182 cases died (overall case fatality ratio 67%). Of the total confirmed and probable cases, 56% (n=1841) were female, 28% (n=926) were children aged less than 18 years, and 5% (n=163) were health workers.
