The World Health Organization declared the last mpox global emergency over in May 2023. And just over a year later, here we are again.

Since the start of 2024, a deadlier, more transmissible strain of the virus has killed about 575 people in the Democratic Republic of Congo and infected 30 times more. New cases have recently appeared in Europe and Asia. In August, the WHO declared a new mpox global health emergency. 

Bloomberg’s Ashleigh Furlong joins host Sarah Holder to explain why the latest outbreak could have been avoided — and what it will cost to beat it.
