A major malaria outbreak in Ethiopia came from an invasive Asian mosquito
In early 2022, malaria cases in the Ethiopian city of Dire Dawa surged, with more than 2,400 people sickened. The spike in infections was the work of an invasive mosquito species that’s spreading across Africa, scientists report.
