Ebola outbreak in Democratic Republic of Congo becomes deadliest in country’s history

An Ebola outbreak in the Democratic Republic of Congo (DRC) has claimed the lives of 2,325 individuals, making it the deadliest Ebola outbreak in the nation's history, according to government data released on Sunday. The outbreak, now the 17th in DRC's history, has seen case numbers rise to 4,945, with 101 new cases detected in the past 24 hours.

The situation took a concerning turn as the case fatality ratio, which measures the proportion of people dying from the outbreak after a confirmed infection, rose from approximately 20% in early June to 46%. This surge in fatalities indicates that a majority of confirmed cases are now proving fatal. Public health experts suggest that this trend does not imply the virus has become more lethal, but rather highlights persistent issues in surveillance, case detection, and access to care.

The current outbreak is caused by the Bundibugyo species of Ebola, which lacks approved vaccines or treatments. Since the outbreak was declared on May 15, weak health infrastructure, community resistance, and instability have hindered efforts to identify and respond to cases. The case fatality ratio has notably increased from around 20% in early June to 46%, signifying that almost half of the confirmed cases now result in death.

While experimental vaccines and therapies are being evaluated, global health authorities are assessing the potential of existing Ebola treatments to offer protection. However, evidence so far is limited to animal studies. Prior to this outbreak, DRC's deadliest Ebola outbreak occurred from 2018 to 2020, with a total of 2,299 reported deaths.
