Oral Cholera Mass Vaccination Campaign Coverage Survey in Ayod County, Jonglei State, South Sudan
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.
