Humanitarian partners have stepped up response to the outbreak...Projections of 15,000 severe and 60,000 moderate cases over the coming months have led to plans for a significant and rapid scale up of the response. To help stabilize and contain the outbreak, the CERF rapid response grant of $2 million will strengthen and complement response activities already underway by WASH and Health partners. (OCHA, 30 May 2016)

Since the beginning of [2016], a total of 14165 case of AWD and 497 deaths have been reported in different parts of Somalia. Of these 47.7% are female while 57.9% are children below 5 years. [...] there has been a gradual reduction in number of cases from the peak 1,853 cases and 187 deaths (CFR 10.0%) in week 15 to 194 cases and 0 death in week 46. (WHO, 20 Nov 2016)

Drought conditions have increased the spread of epidemic-prone diseases such as acute watery diarrhoea, cholera and measles. In the first 7 weeks of 2017, more than 6000 cases and 65 deaths by acute watery diarrhoea/ cholera were reported. (WHO, 27 Feb 2017)

The AWD/cholera epidemic in Hiraan, Nugal, Mudug and Bari and Banadir region has been controlled and the cholera treatment centre in Beletweyne has been closed. 2016's outbreak was one of the worst and longest in which the country has experienced in the last five years. (WHO, 5 Mar 2017)

On 15 March 2017, the Government of Somalia, together with humanitarian partners, launched an Oral Cholera Vaccination campaign, the first of its kind in Somalia, targeting over 450,000 people in seven high-risk areas around the country...WASH partners have furthermore scaled up response to AWD/Cholera, reaching 316,000 people in southern and central Somalia through distribution of hygiene kits, chlorination of water points and hygiene promotion campaigns as of end of February. In total, some 568,600 people were assisted with temporary and/or sustainable access to safe water, 36,000 people with safe sanitation and 498,000 people with hygiene promotion activities. (OCHA, 24 Mar 2017)

In 2017, a total of 53,015 AWD/Cholera cases have been reported across 52 districts in 16 regions, including 795 deaths (CFR 1.5 per cent). This represents the worst case scenario with an attack rate (AR) of 5.5 per 1,000 people. 41 per cent of the cases are among children below five years with a slightly higher CFR (1.8%) compared to children above five years (1.4 per cent). The number of AWD/Cholera cases in 2017 is more than three times the 2016 caseload, and 10 times the 2015 caseload. Whilst the cumulative CFR is declining from 2.3 per cent at the beginning of the outbreak to 1.5 per cent as of last week, the reported CFR from inaccessible areas is still four times higher. (UNICEF, 30 Jun 2017)

Over the past two months there has been a significant reduction in the number of new AWD/Cholera cases in all regions of Somalia. No AWD/cholera related deaths have been reported since August in any region across Somalia. (Health Cluster, 31 Oct 2017)

As of 18 March 2018, a total of 1613 cholera cases, including nine deaths (case fatality rate = 0.6%), have been reported from four regions: Hiraan, Banadir, Lower Juba and Middle Shabelle. The outbreak started in Beletweyne, Hiraan Region; it spread to Banadir Region in early January 2018, to Lower Juba in early February 2018, and to Middle Shabelle in early February 2018... Banadir Region is one of the regions with the highest concentration of internally displaced persons (IDPs). (WHO, 29 Mar 2018)

Following the heavy rains that have led to the floods in the Juba land and Shabelle basins, there has been an observed increase in the number of new AWD/Cholera cases. The cholera outbreak that started in December 2017 in Beletweyne along river Shabelle has spread to Jowhar, Kismayo, Afgoye and Banadir. The cholera spread is expected to increase due to the floods that have led to contamination of water sources in the flood affected regions. Floods have also led to blockage of access of health services which will contribute to delayed health seeking by the affected populations with... A cumulative total of 3,280 cases including 21 deaths have been reported since December 2017. (WHO, 13 May 2018)

The cholera spread is expected to increase due to the floods that have led to contamination of water sources in the flood affected regions...Over the past 2 weeks, there has been decrease in the number of AWD/Cholera cases reported in Lower Shabelle, Banadir and Lower Jubba; the regions that are affected by floods. In week ending 8th July, active transmission of AWD/cholera was reported in Kismayo district in Lower Jubba, Afgoye Kurtunwarey, Brava and Merka in Lower Shabelle as well as in 14 districts of Banadir region (Darkenly, Daynile, Hodan, Madina, Waberi, HamarWeine, Hamarjabjab, Wardhigley, Shibis,Yaqshid, Abdiaziz, Kaaran, Huruwa, and Howlwadag districts).

(WHO, 8 Jan 2019)

Since the beginning of the outbreak a total of 7,104 including 46 deaths (CFR 0.7%). However; the drought affecting many parts of the country has led to limited access to safe water and food insecurity and this is expected to lead to increased spread of cholera cases to other regions. (WHO/Health Cluster, 30 Apr 2019)

Since December 2017, a total of 7,994 cumulative cases including 46 deaths (CFR 0.6%) were reported from 3 states of Somalia (Hirshabelle, Jubbaland and South West state) and Banadir region. The first round of Oral cholera vaccination (OCV) campaign targeting 650,000 people aged 1 year and above was started on 22 June 2019 in the districts of Kahda, Heliwa, Harmajajab, Balad, Afgoi and Kismayo.

The cholera outbreak has been contained in the districts of Jubaland, Hirshabelle and South West States following the implementation of oral cholera vaccination (OCV) campaigns and other health interventions in these areas. Active transmission is still reported in Banadir and Lower Jubba regions. These areas have experienced heavy rains in the recent past that may have contributed to the contamination of water sources leading to the continued cholera transmission. The most affected districts in Banadir are Darkenley, Madina and Hodan, while in Lower Jubba it is the district of Badhadhe. (WHO, 22 Oct 2019)
