Districts Reporting Cases in Week 22 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 (fig 4) below. The cholera outbreak that started in December 2017 in Beletweyne along river Shabelle has spread to Jowhar, Kismayo, Afgoye Merka 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. Over the past 2 Weeks, there has been an increase in the number of AWD/Cholera cases reported in Lower Shabelle, Banadir and LowerJubba; the regions that are affected by floods. In week ending 3rd June, active transmission of AWD/cholera was reported in Kismayo district in Lower Jubba, Afgoye and Merka in Lower Shabelle as well as in 11 districts of Banadir region (Darkenly, Daynile, Page 3 of 15 Hodan, Madina, Waberi, HamarWeine, Hamarjabjab, Heliwa, and Kaaran, Yaqshid, Howlwadag districts). In Kismayo, affected communities especially in Farjano IDP are reportedly using contaminated water due to floods. There was an increase in the number of cases reported from 357 in week 21 to 396 in week 22. The Oral Cholera Vaccination that was implemented in 11 high risk districts in 2017 of the central region has greatly contributed to the reduction in the number of new AWD/cholera cases compared to the same time in 2017.
