  {Excerpt} On Sept 4, 2025, the DR Congo Government and Ministry of Health announced a new Ebola virus disease outbreak in the Bulape health zone (Kasai province), marking the end of over 15 years without any reported cases of Ebola virus disease in this region . As of Sept 14, 2025, there were 35 confirmed Ebola virus disease cases and 16 deaths , representing a case fatality rate of 45·7%.1,2 This unexpected resurgence in a region with insufficient preparedness capacity raises serious concerns about potential regional spread, including towards neighbouring Angola. At the same time, DR Congo is experiencing one of the most severe cholera outbreaks of the past decade , with a total of 48 139 cases and 1443 deaths reported between Jan 1 and Aug 24, 2025, resulting in a case fatality rate of 3%.3 By epidemiological week 33, high case fatality rates were reported in the provinces of Kwilu (76 cases, 26 deaths; 44%), Sankuru (42 cases, 6 deaths; 14%), and Equateur (224 cases, 19 death...

  Abstract The current panzootic of high pathogenicity avian influenza (HPAI) H5N1 has been catastrophic for wildlife , and following a significant sweep, clade 2.3.4.4b is found in every region aside from Oceania . Herein, we report the results of our third year of targeted surveillance of incoming migratory seabirds and shorebirds into Australia . We did not find evidence of HPAI H5N1 in any of the birds tested , and there were no reports of HPAI H5N1 in wildlife tested through other surveillance schemes in 2024. Unlike previous years, we detected a diversity of low pathogenicity avian influenza (LPAI) viruses in shorebirds. Through phylogenetic analysis we revealed that the H3N7 and H4N7 viruses recovered from Red-necked Stints were complex mosaic viruses, comprising segments of Eurasian, Australian shorebird, and Australian waterfowl segments . A H1N7 virus detected comprised a wholly Eurasian introduction , confirming this route for avian influenza viruses into Australian ecos...
