[2] The pandemic reached Northern Africa in 1865 and spread to sub-Saharan Africa, killing 70,000 in Zanzibar in 1869–70. [3]
Additionally, there have been many documented major local cholera outbreaks, such as a 1991–1994 outbreak in South America and, more recently, the 2016–2021 Yemen cholera outbreak. [ 2 ] Although much is known about the mechanisms behind the spread of cholera , this has not led to a full understanding of what makes cholera outbreaks happen ...
Cholera dissemination across Asia and Europe in 1817–1831. In the years after the pandemic subsided in many areas of the world, there were still small outbreaks, and pockets of cholera remained. [8] In the period from 1823 to 1829, the first cholera outbreak remained outside of much of Europe. [8]
Recent major outbreaks are the 2010s Haiti cholera outbreak and the 2016–2022 Yemen cholera outbreak. In October 2016, an outbreak of cholera began in war-ravaged Yemen. [87] WHO called it "the worst cholera outbreak in the world". [88] In 2019, 93% of the reported 923,037 cholera cases were from Yemen (with 1911 deaths reported). [89]

The CDC reports the highest level of flu cases since the swine flu pandemic of 2009. For the first time, the death rate for flu cases is higher than the mortality rate for COVID-19.
Today we report on new genetic research that may lead to tools or treatments to prevent cholera outbreaks, and on a study of a potentially practice-changing approach to treating some liver tumors.
Cholera infections are most commonly acquired from drinking water in which V. cholerae is found naturally or into which it has been introduced from the feces of an infected person. Cholera is most likely to be found and spread in places with inadequate water treatment, poor sanitation, and inadequate hygiene.
