Risk of the virus being transmitted to neighboring countries is "very high," WHO officials said, although outside of the immediate region, risk remains low.
Two Ebola fatalities were confirmed in Uganda in June, after the victims returned from a funeral in DRC. Kenya and Rwanda have also been on high alert for signs that the virus may have entered the country.
Efforts to contain the disease have been hampered by misinformation and distrust on the part of local communities, who in some cases have retaliated against health teams by attacking them. Nearly 200 attacks on medical centers and staff have been reported this year, according to the BBC. This has limited many of the health services that non-governmental organizations are able to provide.
Catholic Relief Services has been supporting local Caritas partners in responding through education campaigns to help residents know how to prevent and respond to the virus.
More than 160,000 people have received the Ebola vaccine, which is 99% effective, according to the BBC, but many more are fearful of it and refuse to receive it. In addition, violence in the eastern part of the DRC has made it difficult to reach some areas of the country, and difficult to monitor the virus as it spreads.
During the 2014-2016 outbreak in West Africa, the worst in history, Catholic Relief Services and Caritas worked to treat those who were infected, support Ebola orphans, provide food support and educate people on hygiene practices to help avoid the spread of the virus, such as hand washing and avoiding contact with dead bodies.
