Ebola Outbreak in DRC Could Be Mutating, Officials Warn 2026

The Ebola outbreak in the Democratic Republic of the Congo (DRC) is now the second-largest on record, and health officials fear the virus could be mutating as confirmed cases pass 4,000. The Bundibugyo strain has caused unprecedented severity, prompting urgent investigations into potential genetic changes.

Ebola Outbreak in DRC: Unprecedented Scale and Severity

As of 4 August, the DRC’s national public health institute reported 3,973 cases and 1,801 deaths, with numbers continuing to climb. Dr Jean Kaseya, director general of the Africa Centres for Disease Control and Prevention (Africa CDC), confirmed that cases have now topped 4,000, making this outbreak the second-largest Ebola outbreak ever recorded.

Compared to the West Africa Ebola outbreak of 2014-18, this current crisis has eight times more cases and six times more deaths at the 11-week mark. The West Africa outbreak eventually infected over 28,000 people and killed at least 11,000, but the rapid escalation here is alarming experts.

Possible Mutation of the Ebola Virus

Officials are particularly concerned about the possibility of viral mutation. Kaseya stated that he and WHO Director General Dr Tedros Adhanom Ghebreyesus plan to conduct studies “to check if there is no additional issue, or maybe if the virus is not mutating. Because the level of severity of this Bundibugyo outbreak is unprecedented.”

This mutation concern is driven by the unusual severity and transmission patterns observed. More than two-thirds of Ebola deaths are occurring in communities rather than treatment centers, indicating high levels of untracked transmission.

Key Challenges in the Ebola Response

Contact tracing in the DRC is proving insufficient. For every Ebola patient, only 10 contacts are identified on average, far below the expected 40. This gap allows the virus to spread silently through communities.

In an MSF-run treatment center in Bunia, 90% of admitted patients are not on authorities’ lists of known contacts. This suggests that many infections are occurring outside of monitored networks, making containment extremely difficult.

Scaling Up the Fight Against Ebola

Africa CDC has announced plans to scale up every aspect of the response, including going “door to door” to find patients. “The time for incremental action is over,” Kaseya emphasized, signaling a more aggressive approach to curb the outbreak.

Ebola is a viral hemorrhagic fever that causes vomiting, diarrhea, organ damage, and internal bleeding. The current outbreak began in May, though officials suspect it may have been spreading since January.
