UN warns of cholera risk for one billion people in 43 countries.

A new report by the UN warns that about 100 crore people, particularly children, in 43 countries are at risk of cholera. After years of steady decline, cholera is devastatingly coming back and targeting the world's most vulnerable communities. The report blames a deadly combination of climate change, underinvestment in water, sanitation and hygiene services for the spread of the disease. Although vaccines exist to protect against cholera, supply is insufficient to face the increasing demand. The WHO is launching a 12-month Strategic Preparedness, Response and Readiness Plan, requiring $160 million, alongside Unicef's Call to Action for $480 million to respond to the growing cholera threat.
