Humanitarian workers are struggling to calm community fears in strife-torn eastern Democratic Republic of Congo, where 125 people have died of Ebola, and cases of the virus are spreading fast.The World Health Organisation said on Friday that 200 cases of the deadly virus have been registered in the outbreak first detected on August 1, with 165 of them laboratory confirmed and 35 considered probable.The UN agency voiced concern over the swelling number of cases in recent weeks, especially in the town of Beni, near the Ugandan border."Insecurity that has increased in the city is one of the reasons why we are seeing these new cases coming up," WHO spokesperson Tarik Jasarevic told reporters in Geneva.The latest outbreak - the 10th in DRC since Ebola was first detected there in 1976 - emerged in the highly-restive northeastern region of North Kivu, which is home to a clutch of armed groups.The authorities in Beni have announced measures to protect health workers after a number of incidents where response teams were assaulted.Fears and misconceptions about the virus have led to widespread mistrust and resistance to Ebola response workers, including those who come into communities wearing hazmat suits to orchestrate burials. Red Cross workers injured Two Red Cross volunteers were seriously injured when they were attacked during the burial of a suspected Ebola victim last week.The International Federation of Red Cross and Red Crescent Societies (IFRC) told AFP on Friday that it was doing everything it could to minimise the risk to its volunteers on the ground.But IFRC Secretary-General Elhadj As Sy stressed that the organisation would never resort to using armed escorts in the areas."We never use military or armed group protection to do our work... That is not part of our modus operandi," he told AFP.He said it was not surprising that people living in an area affected by armed conflict would be "totally overwhelmed with another shock like the Ebola crisis," and might have "wrong reactions". "It is not unusual for us to experience these kind of difficulties," he told AFP, adding that much of his organisation's work involved engaging with community members to build acceptance of the Ebola response work. While IFRC is taking "additional safeguards" to protect its volunteers, Sy stressed that there were no plans to withdraw from problematic areas."It is exactly when it is most difficult, in the time that it is most risky, that we are needed most," he said.WHO meanwhile did temporarily suspend its work trying to halt the outbreak in Beni last month amid increased attacks by armed oppositions groups.Jasarevic said Friday that the agency had resumed its work there, but lamented that continued attacks and violence between government and rebels, while not directly targeted at Ebola responders, meant teams were "not able to function fully"."On a daily basis, we can't go for a couple of hours to some areas because there is either a shooting going on, or there is a protest by groups in the city against this violence," he said.* Sign up to News24's top Africa news in your inbox: SUBSCRIBE TO THE HELLO AFRICA NEWSLETTERFOLLOW News24 Africa on Twitter and Facebook.
