Some 635 Ebola cases have been confirmed and 127 people have died from the dangerous infectious disease in the Democratic Republic of Congo, the Africa Centres for Disease Control and Prevention (Africa CDC) said on Thursday.

The increase in confirmed cases can in part be attributed to a rise in testing and contact tracing, the World Health Organization said last week

Rising Ebola cases in eastern Congo are intensifying concerns among health officials as the outbreak continues to spread across Africa.

Three major laboratories in the Democratic Republic of Congo have run out of Ebola testing kits as infections continue to mount, the World Health Organization has said.

The Ebola outbreak in the Democratic Republic of the Congo and Uganda could lead to more than 20,000 cases and over 2,000 deaths in a worst-case scenario, according to a CDC report.

Congo’s Ebola outbreak “had a big head start, and we’re still behind,” World Health Organization Director-General Tedros Adhanom Ghebreyesus said Wednesday, but asserted that “we are catching up” as testing improves.

A new Ebola outbreak in a remote province in Congo has caused 65 deaths and 246 suspected cases so far, Africa CDC says.

The World Health Organization said on Thursday that the risk of Ebola transmission in Europe and World Cup host countries is low as the tournament gets ready to kick off across the U.S., Canada and Mexico.
