WHO Warns Most New Ebola Cases In Congo Linked To Unknown Transmission Chains

Health officials say the virus is spreading faster than response teams can contain it, raising the risk of wider community transmission.

WHO: Virus Has Spread Undetected
Most of the recent Ebola cases are not linked to previously identified patients or known contacts, the WHO’s emergencies chief said. 

That suggests “unknown transmission chains” — infections spreading through communities unnoticed. This development makes it much more difficult to identify cases and break the cycle of transmission.

Efforts to Respond Outrun Outbreaks
The WHO said the outbreak is still outstripping medical and public health efforts on the ground. 

Response hampered by several challenges:
Delayed case detection in remote areas due to limited access
Overburdened health systems in eastern Congo
Security issues restricting the movement of health workers

Hence, teams are finding it hard to manage new infections.

Contact Tracing Problems
“The big problem right now is contact tracing. Without knowing where patients picked up the virus, it is difficult to trace and monitor others who might have been exposed.

Health authorities say the gap is allowing the virus to spread more widely before infections are even identified.

WHO Issues Call for Urgent Action
The WHO is calling for urgent action to stay ahead of the outbreak. Priorities are beefed-up disease surveillance, faster testing, expanded vaccination campaigns, and more international support.

The best way to reduce deaths and stop the spread in the community is early detection and prompt treatment, experts say.

The agency says containing the outbreak will be contingent on quickly identifying the undetected cases before they start new chains of infection.
