⚡ TL;DR

The Bundibugyo virus Ebola outbreak in the DRC has now spread across 60 health zones in 6 provinces and is the largest Ebola outbreak ever recorded in that country, with no sign of slowing. ^[1]

Overall mood: Grave on outbreak front, cautiously active on longevity science and drug pipeline.

🦠 OUTBREAKS & VIRUSES

EBOLA (BUNDIBUGYO VIRUS) - DRC AND UGANDA: THE BIGGEST STORY

• As of August 28, 2026 the DRC Bundibugyo virus disease (BVD) outbreak spans 60 health zones across 6 provinces: Bas-Uele, Haut-Uele, Ituri, North Kivu, South Kivu, and Tshopo. ^[1]
• Six additional health zones were added in the reporting window since the August 14 Disease Outbreak News update, signaling rapid geographic acceleration. ^[1]
• WHO characterized this as the largest Ebola outbreak ever reported in DRC and noted it is expanding faster than any previous Ebola outbreak in the country. ^[2]
• Cross-border transmission to Uganda has been confirmed and sustained; CDC mobilized an international response in May 2026 and expanded enhanced airport screening to Washington-Dulles and Atlanta. ^{[3] [4] [5]}
• As of July 1, 2026 update, 1,460 confirmed cases and 452 deaths had been reported from DRC alone; by July 15 that figure rose to 2,124 confirmed cases and 828 deaths. ^{[5] [6]}
• The outbreak originated in Mongbwalu Health Zone, Ituri Province, first alerted to WHO on May 5, 2026, and confirmed as Bundibugyo virus by the Institut national de recherche biomedicale (INRB) on May 14, 2026. ^[7]

HANTAVIRUS - M/V HONDIUS CRUISE SHIP, MULTI-COUNTRY

• Seven initial cases (2 confirmed, 5 suspected) were reported among 147 passengers and crew; subsequent updates expanded the case count with additional laboratory-confirmed ANDV infections. ^{[9] [10]}
• The outbreak is notable for Andes hantavirus, the only hantavirus with documented person-to-person transmission, presenting in a mass-gathering cruise ship context. ^[8]
• CDC provided regular response transcripts through June 24, 2026, and classified U.S. public risk as extremely low.

NIPAH VIRUS - KERALA, INDIA
