Cholera epidemics continue to be a major public health problem in many countries around the

A dose of oral vaccine provides effective short-term protection against cholera during an outbreak, a study in Zambia shows.
According to researchers, a shortage in the global stockpile of cholera vaccines meant that single-dose oral vacc...ination was necessary to tackle an outbreak in Lusaka, Zambia, in February 2016. The emergency vaccination campaign was implemented in April 2016, targeting more than 500,000 people in Lusaka’s overcrowded township areas.
The 2016 outbreak happened when Zambia had not reported a case of cholera in four years.
To determine the effectiveness of the single-dose cholera vaccine, the researchers enrolled 66 patients with confirmed cholera and 330 people without the disease who were neighbours of the patients.
According to the study the effectiveness of the single dose vaccination was about 90 per cent.

The cholera outbreak has affected 14 countries in the WHO African Region. The climate-induced natural disasters such as cyclone and flooding in the southern African region and drought in the Horn of Africa led to increase in cases of cholera in many of the affected countries. With the rainy season c...ommencement in the west African region there is risk of more cholera outbreaks on the horizon. The trend across the region is being closely monitored and this highlights the need for Member States to enhance readiness, heighten surveillance and institute preventive and control measures in communities and around border crossings to prevent and mitigate cross border infection. Since 1 January 2022, a cumulative number of 213 443 cholera cases has been reported to the WHO Regional Office for Africa (AFRO), including 3 951 deaths with a case fatality ratio (CFR) of 1.9% as of 16 July 2023 (Table 1). Malawi accounts for 28% (58 941) of the total cases and 45% (1 766) of all deaths reported, and together with Cameroon, Democratic Republic of the Congo, Mozambique, and Nigeria contribute to 85% (181 300) of the overall caseload and 88% (3 464) of cumulative deaths. In Epidemiologic week 28, six countries Burundi, Cameroon, Ethiopia, Kenya, Malawi and Mozambique reported a total of 667 new cases.

The report offers 20 top recommendations for getting ahead of future outbreaks in Yemen and similarly complex humanitarian settings.
In 2015, Yemen was declared a Level 3 emergency by the UN, kicking into gear the highest level of humanitarian support. A massive cholera outbreak followed, leading t...o 1 million suspected cases in 2 waves from September 2016-July 2018.
“We largely know ‘what to do’ to control cholera, but context-specific practices on ‘how to do it’ in order to surmount challenges to coordination, logistics, insecurity, access and politics remain needed,” the report states.
While the response improved between the 2 waves, there were gaps. For one, Yemen’s history of cholera should have triggered a heavy focus on pre-planning for an epidemic, such as stockpiling supplies and doubling down on community-based surveillance, the report fou
