Bundibugyo Virus Outbreak:
The World Health Organization declared the Ebola outbreak caused by the Bundibugyo virus in the Democratic Republic of the Congo and Uganda as a Public Health Emergency of International Concern (PHEIC).
- The outbreak has exposed a major gap in global vaccine preparedness, as there is currently no licensed vaccine or specific therapeutic for Bundibugyo virus.
- Bundibugyo virus is one of the species of the Orthoebolavirus genus that causes Ebola Virus Disease (EVD). It is a zoonotic disease, with fruit bats considered the most likely natural reservoir.
- Human infection occurs through direct contact with infected wildlife such as bats and non-human primates.
- The disease further spreads through contact with the blood, bodily fluids, secretions, or contaminated surfaces associated with infected individuals.
- Transmission risk becomes especially high in healthcare settings with weak infection prevention measures and during unsafe burial practices.
- The incubation period ranges from 2 to 21 days. Infected individuals generally become contagious only after the onset of symptoms.
- Early symptoms are non-specific and include fever, fatigue, headache, muscle pain, and sore throat, making diagnosis difficult in the initial stages.
- As the disease progresses, patients may develop gastrointestinal complications, organ failure, and haemorrhagic symptoms.
- Past outbreaks reported in Uganda and the Democratic Republic of the Congo during 2007 and 2012 recorded case fatality rates ranging from nearly 30% to 50%.
- BVD closely resembles other endemic febrile illnesses such as malaria, making laboratory confirmation essential.
- Detection is carried out through PCR testing and antigen or antibody-based diagnostic assays.
- As there are currently no approved vaccines or specific treatments for BVD, containment relies on rapid case detection, isolation and supportive care, contact tracing, safe burial practices, and strong community awareness and engagement.
