A fresh outbreak of Ebola has emerged in the Democratic Republic of Congo and Uganda, with nearly 400 confirmed cases and more than 100 fatalities reported. To understand the origins of this outbreak, the measures authorities are taking to contain it, and why this particular episode is raising alarm, Ian Sample speaks with Daniela Manno, a clinical epidemiologist from the London School of Hygiene and Tropical Medicine.
How Does Ebola Spread?
Ebola is transmitted through direct contact with bodily fluids of infected individuals or contaminated materials. The virus can enter the body through broken skin or mucous membranes. Fruit bats are considered natural hosts, and human outbreaks often begin through contact with infected animals.
Containment Challenges
Containing Ebola requires rapid identification of cases, isolation, contact tracing, and safe burials. In the current outbreak, challenges include remote locations, community mistrust, and concurrent health crises. Vaccination campaigns are underway, but logistical hurdles persist.
Why This Outbreak Is Concerning
This outbreak has crossed borders into Uganda, raising fears of wider regional spread. The strain is the Zaire species, which has high fatality rates. International health authorities are on high alert, with the World Health Organization considering a global health emergency declaration.
