Abstract:

In South Sudan there was cholera outbreak since 2014 affecting more than 14 counties. In response to the outbreak on June and July 2017, an oral cholera vaccination (OCV) campaign was conducted in Ayod County in four payams such as Jiech, Kandak, Karmuom and Padek. To assess the coverage of the vaccination, Post Campaign Evaluation survey was conducted in the above mentioned four payams. Cluster survey sampling methodology was used to determine sample size. From four targeted Payams in total 1,326(364 from Jiech, 350 from Kandak, 264 from Padek and 348 from Karmuom) respondents interviewed. The respondents categorized in to three age groups (1–4, 5–14, >15 years). The finding indicated different vaccination coverage in each Payams 86.1% (95% C.I 82.2%-89.9%) in Jiech, 81% (95% C.I 74.3%-87.9%) in Kandak, 88.6% (95% C.I 84.1%-93%) in Padek and 84.6% (95% C.I 79.9%-89.2%) in Karmuom. People who received two-doses of vaccination above 15 years of age were 84.3% (94% C.I 81.2%-87.5). The overall gender representativeness was marked by a big respondent of female compare to male respectively 536 and 464 with respective coverage of 53.6% (95% C.I 49.3-57.8) in female and 46.4% (95% C.I 41.8-50.9) in male. However, the complete two dose coverage was high in male 86.8 % (95% C.I 83.5-90.1) and female 84.3 (95% C.I 80.9-87.6). Kandak has the lowest coverage 81(74.3-87.9) of all payams. Based on the population structure and the target for reaching with oral cholera vaccination, the vaccination coverage is at the acceptable range to provide prevention and to interrupt transmission of infection.
