The number of confirmed Ebola cases in the Democratic Republic of Congo surpassed 1,500 on Friday after more than 40 new infections were reported, official data showed, as response and surveillance measures continue.

The death toll has also risen to 473 since the outbreak was declared on May 15, according to a health ministry situation update released on Saturday.

The outbreak remains concentrated in 34 health zones in Ituri, North Kivu and South Kivu provinces, with more than 11,000 contacts being monitored.

Health authorities reported 213 recoveries, while 628 patients remain under care.

The ministry said community mobilisation capacities continue to be strengthened amid community resistance, particularly in Ituri.

The Africa Centres for Disease Control and Prevention (Africa CDC) earlier this week convened a high-level meeting in the capital, Kinshasa, to align political leadership, partners, and resources behind what it called one priority: supporting Congo faster and protecting the region.

Speaking at the forum on Thursday, President Felix Tshisekedi emphasised the need for solidarity and strengthening the African continent’s health capacities for an effective response to epidemics.
