  • The 2014–2016 West Africa Ebola epidemic was far larger than the current outbreak, reaching Guinea, Liberia and Sierra Leone and causing roughly 28,600 cases and 11,300 deaths; it was controlled only over many months through case isolation, contact tracing, safe burials and clinic infection control, scaled up mainly in 2014 and 2015.

  • Ebola vaccines were not part of the early response in 2014 because no vaccine was yet approved; later outbreaks in DR Congo (2018–2020) and Uganda (2022) were contained faster partly because vaccines and treatments existed by then. Hephaestus
  • The current outbreak now has cases in DR Congo, Uganda, Kenya and Nigeria. Nigeria's first case in over a decade is a Ugandan-born wife of a Swiss diplomat in Abuja, who had not travelled to Congo and is believed by Swiss authorities to have been infected in Uganda, though Kampala says Uganda is Ebola-free.

  • Kenya has recorded two deaths, both linked to a man who had travelled from DR Congo; the second, a 65-year-old close relative, developed symptoms in quarantine. Health officials say all cases are in one cluster with no evidence of community spread. Iris
  • The WHO has started a clinical trial in Bunia, DR Congo, testing whether Ervebo, approved for the Zaire strain, gives cross-protection against the Bundibugyo virus behind this epidemic. Uganda has ordered a 21-day quarantine for citizens returning from DR Congo. Iris

Still open: Where the Nigerian patient was infected, since Swiss authorities point to Uganda while Kampala says it is Ebola-free, and whether the current cluster can be contained as quickly as earlier outbreaks.

Switzerland says Nigeria's first Ebola patient in more than a decade, the Ugandan-born wife of a Swiss diplomat in Abuja, had not travelled to Congo and is believed to have caught the virus in Uganda, as health officials across Africa try to establish how she was infected. The Guardian

With cases now in Congo, Uganda, Kenya and Nigeria, what would you most want health authorities to make public about how this outbreak is spreading?

@ai weren’t they able to control a previous spread across even more countries?

Partly. The 2014–2016 West Africa epidemic was far larger: it reached Guinea, Liberia and Sierra Leone, with a few cases in Nigeria, Senegal, Mali and the United States, and some in Europe, and the WHO counted roughly 28,600 cases and 11,300 deaths. It was not brought under control quickly. Recognition was late, the first response was overwhelmed, and transmission ran for months, partly because of burials, community mistrust and health workers who were infected. Control came from the usual tools, done at scale: isolating cases, tracing contacts, safe burials and infection control in clinics. Most of that scaling-up happened in 2014 and 2015, and the region was declared free of transmission in 2016. Vaccines were not part of the response at the start, since an Ebola vaccine was still in trials then. Later outbreaks in DR Congo (2018–2020) and Uganda (2022) were contained faster, partly because a vaccine and treatments existed by then. Whether the current cluster follows that path depends on how quickly chains of transmission can be traced, which is the point the WHO situation reports track. The figures I'm giving are from memory, so check the WHO's historical summary of the 2014–2016 outbreak for exact numbers.
