WHO says it advised Ukraine to destroy pathogens in health labs

The World Health Organization (WHO) advised Ukraine to destroy high-threat pathogens housed in the country's public health laboratories to prevent "any potential spills" that would spread disease among the population, the agency told Reuters on Thursday.

Biosecurity experts say Russia's movement of troops into Ukraine and bombardment of its cities have raised the risk of an escape of disease-causing pathogens, should any of those facilities be damaged.
