Hidden Ebola Transmission Challenges Congo Containment

The outbreak, which began in mid-May, has officially claimed 625 lives among 1,792 confirmed cases. However, WHO modelling indicates the actual infection toll could be two to four times higher. In the Ituri province, particularly within the city of Bunia, roughly half of all individuals tested for the virus return positive results, confirming intense and sustained community spread.

Health officials identify the Bundibugyo strain as a significant factor in this silent propagation. The variant appears to produce milder symptoms than other known strains, which may inadvertently encourage infected individuals to delay seeking care. With 70% of early fatalities occurring outside of treatment facilities, the virus continues to move through households before responders can intervene. To counter this, authorities are deploying 21,000 community health workers to conduct door-to-door screenings, attempting to bridge the gap between clinical surveillance and the reality on the ground.
