⚡ TL;DR

The Bundibugyo virus (Ebola) outbreak in the Democratic Republic of the Congo is now the largest Ebola outbreak ever recorded, having expanded to 61 health zones across six provinces with sustained cross-border transmission into Uganda. [1] Mood: deeply alarmed on the outbreak front, cautiously watchful elsewhere as a Listeria outbreak in prepared meals claims new deaths and antimicrobial resistance signals intensify. [2] [3]
