After the Kpangba displacement camp ​became the first in this part of war-torn Congo to record deaths from Ebola two weeks ago, health ‌workers rushed to trace those who had come into contact with the deceased to break chains of transmission.

But the workers - from the provincial health ministry, the World Health Organization and other aid agencies - were forced away by angry locals who denied that the two women had died from Ebola, said ​Jean-Claude Lonzama, the chief doctor for the local health zone of Nizi, a heavily populated mining area.

"Up to ​this day, we are not able to follow up on the contacts of these cases," Lonzama told ⁠Reuters on Saturday.

The standoff has left health authorities flying blind as they try to stave off a surge of Ebola ​cases in this camp of around 30,000 people, most of whom have fled inter-ethnic violence in surrounding areas.

"We have 22 displaced ​persons sites in the Nizi health zone ... with around 81,124 residents," Lonzama said. "This is also our great worry because no preventive measures have been put in place in these sites aside from a few educational messages."

Since the outbreak was declared a month ago, several treatment sites have been attacked ​by locals angry about not being able to bury their loved ones because of precautions taken to keep the virus from ​spreading or convinced Ebola is a hoax.

POOR SANITATION

Aid workers fear Ebola could spread quickly in this and other displacement camps, where hundreds of ‌people sometimes ⁠share a single toilet and open defecation is common, accelerating the spread of what is already one of the world's largest-ever outbreaks.

There are more than 5 million displaced people across the three provinces affected by the outbreak - Ituri, South Kivu and North Kivu - all of which have been devastated by decades of conflict.

In Kpangba, as in towns and rural areas across eastern Democratic Republic of ​Congo where cases have been ​recorded, health workers trying to ⁠contain the outbreak are running up against deep-seated mistrust of the government and outsiders.

The attacks on Ebola treatment sites recall the widespread violence targeting health facilities by civilians and armed groups during ​a 2018-2020 outbreak in eastern Congo that killed more than 25 health workers.

The deaths in ​Kpangba occurred on ⁠May 31 and June 1, but were first made public in a report by the U.N. refugee agency published on Thursday.

According to a Congolese health ministry report seen by Reuters, the first victim, a 60-year-old woman in the camp, tested positive for Ebola on May ⁠30 but ​had, by then, broken out of quarantine and could not be located.

The ​difficulties winning trust from the population, combined with shortages of critical equipment and armed conflict across much of the affected areas, has left health experts deeply ​worried about the prospects for containing the outbreak.
