Since the first disease outbreak news on the global cholera situation was published on 16 December 2022, the global situation has further deteriorated with additional countries reporting cases and outbreaks.

Since mid-2021, the world is facing an acute upsurge of the 7^th cholera pandemic characterized by the number, size and concurrence of multiple outbreaks, the spread to areas free of cholera for decades and alarming high mortality rates.

In 2021, 23 countries reported cholera outbreaks, mainly in the WHO Regions of Africa and the Eastern Mediterranean. This trend continued into 2022 as 30 countries across five of the six WHO regions reported cholera cases or outbreaks. Among those, 14 had not reported cholera in 2021, including non-endemic countries (Lebanon and Syria)^i,ii or countries that had not reported cases over three years (Haiti and the Dominican Republic), while most of the remaining countries reported higher case numbers and case fatality ratios (CFR) than in previous years.

As of 1 February 2023, at least 18 countries continue to report cholera cases (Table 1 A & B). As according to the seasonality patterns large parts of the world are in currently in low or interepidemic transmission period this number could increase in the months to come.
