  • As of July 15, 2026, WHO confirmed 2,124 cumulative cases and 828 deaths from Bundibugyo virus disease (BVD) in the Democratic Republic of the Congo, with cross-border transmission ongoing in Uganda. [1]
  • The case fatality rate among confirmed cases stands near 39%, and geographic spread within DRC continues to accelerate with sustained community transmission. [1]
  • The PARTNERS clinical trial, a WHO-coordinated international study, opened patient enrolment in DRC on July 2 to evaluate the first candidate treatments specifically for Bundibugyo virus disease. [2]
  • WHO added the first molecular diagnostic test for Bundibugyo virus (BDBV) to its Emergency Use Listing on July 2, enabling rapid genetic detection from blood samples. [3]
  • Africa CDC and WHO previously launched a joint continental Ebola response plan targeting US $518 million to support African countries in preparedness and response. [4]
  • WHO released its first comprehensive clinical management guidelines covering all filovirus types including Bundibugyo, Ebola Zaire, and Marburg in June 2026. [5]

ANDES HANTAVIRUS - M/V HONDIUS CRUISE SHIP
