GENEVA - Malawi’s worst cholera outbreak on record has left more than 1,000 people dead even as cases have reached 30,621, health minister Khumbize Chiponda has said. The death toll announced on Tuesday breached a grim milestone and surpassed the largest recorded outbreak, which killed 968 people between 2001 and 2002, according to the World Health Organization (WHO).

In September, the WHO warned that after years of decline, there was a “worrying upsurge” in cholera outbreaks globally, with climate change adding to traditional triggers such as poverty and conflict.
