DRC health ministry said on the 10th the current Bundibugyo ebolavirus outbreak
has 4,209 confirmed cases and 1,916 deaths, a case fatality rate of 45.5%. The
World Health Organization said transmission began earlier than publicly
reported: genomic sequencing suggests the virus may have been circulating
silently as early as February, months before the government’s May 15
announcement. WHO warned the outbreak is accelerating and called for urgent
strengthening of control measures. Authorities have shifted from traditional
contact tracing to door‑to‑door, community‑wide screening for hidden cases and
said expanded screening could cause the outbreak to worsen in the coming weeks.
