Congo authorities report more than 6,000 confirmed Ebola cases and nearly 3,000 deaths

BUNIA, Congo (AP) — Congo’s authorities said Monday that the fastest-growing Ebola outbreak in history has topped 6,000 cases with 2,911 deaths.

More than 1,360 people have recovered from the virus, in what authorities said was an “encouraging” development.

The outbreak in eastern Congo is spreading under extremely difficult conditions, fueled by insecurity, displacement, a health workers’ strike and intense population movements . The situation is particularly concerning at displacement sites, where residents already live in extremely precarious conditions.

Last week, the virus spilled into two new health zones in the region.

The World Health Organization has said that it remains out of control and is on track to surpass the 2014-2016 West Africa Ebola outbreak , the deadliest on record, which killed more than 11,000 people, primarily in Guinea, Liberia and Sierra Leone.

On Saturday, an Ebola response team was attacked on the outskirts of the town of Mambasa in Ituri province while responding to a call to secure a body. Young people armed with machetes stormed the site of the funeral, forcing the team to flee and injuring one member, a representative told The Associated Press.

“We demand greater security so we can operate in the field and do our work without endangering our lives,” said Floribert Magene, a member of the response team.

The outbreak is caused by the Bundibugyo virus, a rare type of Ebola that has no approved vaccine or treatment.

Last week, Congo began vaccinating health and other front-line workers with the Ervebo vaccine that was effective in past Ebola outbreaks caused by a different, more common type called Zaire.

Clinical trials are underway to find a licensed vaccine for the Bundibugyo virus .

Although the current outbreak was declared in mid-May, officials believe it had been spreading since February. It has spread from three health zones to nearly 60, with most cases and deaths occurring outside the network of monitored contacts and within communities.

Efforts to bring the outbreak under control — from limited public gatherings to social distancing and airport closures — have disrupted life in the six provinces, particularly Ituri, which also has been ravaged by rebel violence.

The government has introduced some measures, including installing health and sanitary equipment at some locations, but advocacy groups say more needs to be done to build trust with the community.

While neighboring Uganda declared itself free of Ebola last month , the risk of further cross-border spread remains, the WHO said last week.
