Lassa fever is an acute viral haemorrhagic illness caused by Lassa fever
virus. Primary infection can occur by ingesting or inhaling excreta from
the multi-mammate rat. On January 15th 2016, Lagos State reported
its first case of Lassa fever (LF) following an outbreak in Nigeria which
started in August 2015 and affected more than 26 out of 36 states. We investigated
confirm the outbreak, characterize it, and institute public health actions.
we traced contacts among community members, family, caregivers and healthcare workers and classified as high or low risk based on responses to a standardized questionnaire assessing contact directly or indirectly with a case. We used IDSR standard case definition for LF to identify and line-list cases we captured socio-demographic and clinical information of the cases. All contacts of confirmed cases were also line listed and followed up for 21 days.
we identified 4 cases (all-laboratory confirmed), and two deaths (CFR: 50%). The mean age 34.75 ± 11.9 years, two were female. The cases were not epidemiologically linked and two of them were imported from other states. There was evidence of rat infestation in their homes. We line listed 700 contacts from 6 Local Government Areas (LGA): Ikorodu - 207 (29.6%); Ifako-Ijaye - 100 (14.3%); Mushin - 18 (2.6%); Eti-Osa - 69 (9.9%); Alimosho - 41 (5.9%); and Amuwo-Odofin - 220 (31.4%). Five (0.7%) contacts were epidemiologically linked to Ogun State.
outbreak of LF in Lagos State was confirmed, it was controlled through active case search, effective contact tracing and strict infection control. We sensitized the community and health workers in Lagos State on LF. We recommended that surveillance of LF should be strengthened and efforts at environmental sanitation should be intensified.
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.
