Cameroon: Cholera Outbreak - Jul 2018

Disaster types

The cholera outbreak in Cameroon, officially declared by the Ministry of Health on 15 July 2018, is steadily declining, after peaking in week 29 with 42 cases. In week 32 (week ending 12 August 2018), four new suspected cholera cases were reported, compared to 21 cases reported in week 31 and 40 cases in week 30. Three of the new cases reported during the reporting week came from Central Region and one case from North Region...Insecurity in parts of the country (especially South West Region), where there are reports of frequent kidnappings and attacks by organized group of bandits, may have implications on surveillance and response efforts. Additionally, the presence of large number of refugees (from Central African Republic and Nigeria) living in unsanitary and unhygienic conditions, and with limited access to healthcare services, is an important factor. The rainy season, which began in May, is expected to last until September and could facilitate further spread of the disease. (WHO, 10 Aug 2018)

The cholera outbreak that started on 18 May 2018 (Week 20) in Cameroon is persisting. The outbreak initially spread from the North region of the country to the Central and Littoral regions. Although the North and Littoral regions continue to report new suspected cases, the Central region has not reported suspected cases since 27 August 2018 (Week 35). Since our last report on 7 September 2018 (Weekly Bulletin 36) and as of 24 September 2018, an additional 116 suspected cases and 11 deaths have been reported, raising the total number of suspected cholera cases to 367, including 31 deaths (case fatality ratio 8.4%), 14 of which occurred in the community. (WHO, 1 Oct 2018)

Cholera has been detected in Far North region, bringing to four the number regions where the disease has erupted. Seven of the 38 suspected cases reported between 3 – 12 October were in Far North, where two deaths were also recorded. Humanitarian organizations and the Ministry of Health are working to curb the spread of infection. However, the area where the disease has been detected in Far North is hard to reach due to insecurity and bad roads. Since cholera broke out in July, 470 cases and 34 deaths have been registered.

Outbreak is showing a decreasing trend. Between 12 to 16 October 2018, one case was confirmed in the Littoral region and thirty seven new suspected cases notified in North (n=36) and Littoral. Two deaths were reported in the North. No new case was confirmed in the Central region since the 27 august 2018. (WHO, 19 Oct 2018)

From 23 to 29 October 2018, 44 new suspected cases were reported from the Far North (8 cases with zero deaths) and North (36 cases with three deaths) regions. No new confirmed case has been reported from the Central and Littoral regions since the 27 August 2018 and 11 October 2018 respectively. (WHO, 2 Nov 2018)
