Burundi mystery illness kills five as Africa CDC probes unknown pathogen
An outbreak in Burundi has killed at least five people and sickened 35 since March 30, with a 14% case-fatality rate. Symptoms include fever, vomiting, diarrhea, headache, and dark urine; tests for more than 200 pathogens (including Ebola, Marburg, Rift Valley fever, yellow fever, and Crimean-Congo hemorrhagic fever) were negative. Authorities are conducting animal testing to assess possible zoonotic transmission, while Burundi's health ministry, with WHO support, coordinates surveillance, clinical care, lab work, and sample shipments to DR Congo for further analysis.
