Lassa fever is an endemic Viral Hemorrhagic Fever (VHF) in Nigeria. Improvements
in case detection and treatment outcome could be achieved by understanding the
transmission dynamics better and applying the lessons from previous outbreaks
considering the resource constrained setting. This study assessed age-sex disparities
in treatment outcome using data from 2016/2017 lassa fever outbreak surveillance
Lassa fever surveillance and outcome data from December 2016 to May 2017
from 14 States was extracted from the VHF platform. Univariate and bivariate
analysis were carried out using Epi info 7 for socio-demographics and treatment
outcome. Possible association between treatment outcome and selected variables
(age, sex) were analyzed using Chi square at 0.05 level of significance.
there were 168 confirmed cases of Lassa fever during the study period, data was complete for 139 (82.7%). More men were affected (56%), as 61 of the 139 patients (46%) were female. The median age for all the patients treated was 32 years (IQR 25 - 44). Symptoms at presentation prior to treatment included fever (67%), nausea and vomiting (34.5%), diarrhea (14.4%), and intense fatigue (39%) while only 10.8% experienced unexplained bleeding. A total of 75 (54%) patients were treated and discharged alive, while 64 (46%) died. No significant association was found between gender and treatment outcome (p value = 0.976). Although survival was higher among patients aged 15 to 24 years (72%) and lowest among patients who were 45 years and above (35%), age of the patient was not significantly associated with the adverse treatment outcome (p-value = 0.06).
for the 2016/2017 Lassa fever outbreak in Nigeria, age and sex did not influence
the treatment outcome of the recorded cases. There is a need for further
analysis and more large scale studies on Lassa fever treatment outcomes.
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.
