Situation Overview

  • The cholera/Acute Watery Diarrhea (AWD) epidemic curve shows a declining trend of incidences from week 51 onwards (18 to 24 Dec). The downward trend is occurring in most affected districts, while in some the outbreak is stabilizing. Similarly, the case fatality rate (CFR) of 0.6 percent has been declining steadily since week 41 of 2016 (9 to 15 Oct), when it peaked at 8.6 per cent.

  • As of 11 January, a total of 15,658 suspected cholera/AWD cases were reported from 157 districts in 15 governorates: Al Hudaydah (23 per cent), Taiz (14.7 per cent), Aden (10.2 per cent), Ibb (9.5 per cent), Al Bayda (8.9 per cent), Al Dhale’e (8.2 per cent), Hajjah (7.1 per cent), Sana’a (6.7 per cent), Lahj (5.2 per cent),
    Raymah (3.7 per cent), Amanat Al Asimah (1.6 per cent), and 1.3 per cent from Abyan , Dhamar, Amran, Al Jawf governorates. An estimated 34 per cent of the total suspected cholera/AWD cases are children below five years of age. Cumulatively, 180 (21 per cent) of the samples from 46 districts tested positive for Vibrio Cholera, serotype Ogawa (see Table 3.2).

  • A total of 99 deaths associated with Cholera/AWD have been reported from Aden, Abyan, Al Bayda, Dhamar, Al Dhale’e, Al Hudaydah, Amanat Al Asimah, Hajjah, Ibb, Sana’a and Taizz, of which 11 deaths in Aden, Amran, Hajjah, Raymah, Ibb and Sana’a have been confirmed by laboratory to be cholera. The cumulative cholera case fatality rate (CFR) as of 11 Jan is 0.6%.

  • The attack rate as of 11 January is 6.7 per 10,000 of population compared to 6 per 10,000 of population as of 31 December 2016. The high risk districts based on the attack rate and number of cholera/AWD cases are Mukayras in Al Bayda (187 per 10000); Al Hali in Al Hudaydah (96 per 10000); Sa'fan in Sana’a (92 per 10000); Al Mahabishah in Hajjah (90 per 10000); and Al Husha in Al Dhale'e (55 per 10000) (see figure 1.1). The high attack rate indicates the need to scale up response in these priority districts.

  • More than 20 months of conflict has caused the collapse of basic services and institutions. Only 45 per cent of health facilities are functioning, and even these face severe shortages in medicines, equipment, and staff. The lack of capacity, coupled with predisposing conditions such as population displacement, overcrowding and inadequate sanitation have contributed to the occurrence and spread of the Cholera/AWD outbreak.
