Kenya-linked Ebola case stays central; Irkutsk officials report no plague
The main development in the last 24 hours is continued official and media reporting around a Kenya-linked Ebola case tied to the Democratic Republic of the Congo outbreak, with 1 confirmed case and 1 death in Nairobi and 28 or 23 contacts under observation. Local cholera deaths were newly reported in Walikale, France published fresh dengue and chikungunya surveillance bulletins, and Russian officials again said Irkutsk Oblast has no plague cases.
The sharpest gap remains Ebola totals: WHO's latest retrieved official DRC figure is 7890 confirmed cases and 3799 deaths, while newer media reports cite 8600 to 8665 confirmed cases and 4100 to 4178 deaths, unverified. In Kenya, collected official statements report 1 confirmed case and 1 death, with 28 contacts under observation in one count and 23 in another; in Irkutsk Oblast, officials report 0 confirmed plague cases, 0 suspected cases and no deaths, while unverified posts claim 1 to 2 deaths and about 200 contacts under observation.
Watch next for a direct WHO or Kenyan health update confirming the Nairobi Ebola importation and any secondary cases, and for the final laboratory diagnosis in Irkutsk Oblast. Also watch for fresher official totals on the high-watch Ebola, cholera, measles, diphtheria, respiratory season and antimicrobial resistance records, and on elevated dengue, filoviruses, mpox, polio, chikungunya in Nicaragua, yellow fever in Colombia and dengue in France.
