Congo Ebola outbreak still spreading largely undetected, WHO official says

The Ebola outbreak in parts of the Democratic Republic of Congo is spreading undetected, with a significant portion of new cases having no known links to previous patients, according to a WHO official. This suggests the outbreak's true scale could be two to four times larger than reported. Such undetected spread raises serious concerns about the effectiveness of current containment efforts and highlights the urgent need for more comprehensive surveillance and intervention strategies to prevent a larger public health crisis.
