Health fears are mounting on several fronts today, from industrial disaster to infectious disease. In northern China, a gas explosion at a Shanxi coal mine has killed at least 90 people in one of the country’s deadliest mining accidents in years, with rescuers still searching for missing workers and investigators examining possible safety breaches. In East Africa, Uganda has confirmed three more Ebola cases, bringing its current outbreak total to five and sharpening concern about cross-border spread from neighbouring Congo. Authorities are intensifying contact tracing as the Africa CDC warns that 10 countries in the region could be at risk. Those fears were amplified in eastern Congo, where an Ebola treatment tent was burned for the second time in a week, allowing 18 suspected patients to flee and complicating already fragile containment efforts. Even in Sydney, a taxi driver’s stabbing after a fare dispute underscored the everyday violence confronting frontline workers.
