Lassa fever is an acute viral hemorrhagic disease endemic in West Africa.
It is transmitted to humans via contact with food or household items contaminated
by rodent, mastomys natalensis urine or droppings. Human-to-Human transmission
can occur in communities or hospitals with poor infectious control practices.
The burden of Lassa fever is not known because itís asymptomatic in 80% of cases
in addition to non-specific symptoms. The objective of the study is to describe
the cases in person, place and time which will help inform decision making.
we obtained the suspected Lassa fever cases data for all 18 Local Government Areas (LGA) in Edo State for the period of January to December, 2016. Data abstraction was done to obtain socio-demographic, clinical and laboratory information. A descriptive study was done and Data was analyzed using Epi Info to determine frequencies and proportions. Bivariate analysis was done to determined factors associated with outcome using confidence interval set at 95%.
out of 946 suspected cases, 49 (5.2%) were laboratory confirmed (RT - PCR
positive). Modal age group was 20 - 29 years, 15 (30.6%) and 27 (55.1%) were
males. Esan-West, 12 (24.5%) and Etsako-West, 13 (26.5%) Local Government Areas
had most cases. More cases were recorded between January to April with peak
in February 17 (35.4%). Case fatality rate (CFR) among the 39 cases with known
outcome was 51.3%. CFR among the suspected cases was 8%. Late confirmation of
illness (> 7 days of onset) was associated with death [OR = 2.5 (95% CI 0.6
the peak of the outbreak was in February. Case fatality rate of the outbreak was high with cases detected early having better outcome.
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.
