cholera is an infection caused by Vibrio cholerae, which may lead to severe dehydration and death if not treated. On August 31, 2015, the Kaduna Ministry of Health received a notification of increase cases of vomiting and diarrhoea at Dusten-Abba in Zaria. A response team was sent to confirm the outbreak, describe the socio-demographic characteristics and identify possible risk factors for the outbreak.
we defined cases according to the World Health Organization (WHO) criteria. We conducted an unmatched case-control study and descriptive study. We retrieved line-listed cases at the ward facility. We interviewed cases at the facility and recruited controls from the community, and administered questionnaires to both cases and controls. We analyzed data using Epi-Info7 and Microsoft Excel 2016.
a total of 50 cases were recorded, with a median age of 20 years and age range of 1 - 50 years. There were more females (68%) than males. Majority of cases (52%) were under 20 years. Seven (7) deaths were recorded giving a Case Fatality Rate (CFR) of 14%. The CFR was higher in females (14.7%) than in males (12.5%). The index case was seen on August 29, 2015. The outbreak lasted five days. Last cases were seen on September 2, 2015. Highest number of cases seen in a day (23) was on the third day of the outbreak. Only two cases (4%) had their samples tested using cholera Rapid Diagnostic Test (RDT) and both tested positive. Drinking un-boiled water (OR: 12.67, 95% CI: 2.33 - 68.93) was associated with being a cholera case while regular hand washing (OR: 0.22, 95% CI: 0.06 - 0.90) and proper waste disposal practices (OR: 0.07, 95% CI: 0.02 - 0.36) are protective factors.
our investigation confirmed a cholera outbreak with a high CFR, especially among females. Poor hygienic practices such as drinking of un-boiled well water, improper waste disposal and not washing hands regularly were found to be factors that propagate the outbreak. We recommend that messaging that encourage good hygienic practices be intensified by the government officials in Zaria.
Nigeria CDC/Nigeria Field Epidemiology and Laboratory Training Programme 2<sup>nd</sup> Annual Scientific Conference (Abuja)
To create a platform for epidemiologists and public health physicians to share their scientific works, NCDC/NFELTP organized the 2nd annual scientific conference with the theme "strengthening one health through field epidemiology training" at Transcorp Hilton Hotel, Abuja, Nigeria from July 5-7, 2017. The objectives of the conference were to provide residents and graduates a forum to share findings from their field activities; provide training opportunity for trainees on scientific communication; provide an opportunity for epidemiological networking as well as create a forum to discuss pertinent public health issues. In attendance were dignitaries from the United States Centers for Disease Control and Prevention (CDC), USAID, WHO, Africa CDC, Ministries Departments and Agencies, University officials and other implementing partners. With the current rise in zoonotic diseases, the conference also featured a two-day pre-conference workshop on One Health which prioritized zoonotic infectious diseases in Nigeria using standardized prioritization methods. A second workshop focused on antimicrobial resistance. There were 38 oral presentations, 60 poster presentations and 2 plenary sessions. The presentations covered various sub-themes ranging from outbreak investigations, case management, health system strengthening, vaccine preventable diseases, communicable diseases and surveillance. The conference featured a National Night and climaxed with awards to outstanding presenters.
