Lassa fever (LF) is an acute, highly infectious, viral haemorrhagic fever
caused by Lassa virus. It is endemic in parts of West Africa. It is a zoonotic
disease, person-to-person and laboratory transmissions are common, particularly
in hospitals lacking adequate infection prevention and control measures.
An outbreak of Lassa fever was reported in November 2016 in Taraba State,
Nigeria. We confirmed the outbreak, determined its extent, characterized
and instituted public health actions.
during the outbreak, a case was defined as any person resident in Taraba State with severe febrile illness that is not responsive to the usual therapy for causes of fever in the area with or without sore throat and at least one of the following; bloody stools, bloody vomiting, bleeding into the skin and unexplained bleeding from the nose, vagina or eyes from 1st November 2016. Hospital records and surveillance reports were reviewed. The outbreak was described by time, place and person. Data was analyzed using Microsoft excel.
the first case occurred in November, peaked in December and decreased in January with highest (36%) in Karim Lamido LGA. Seven LGAs were affected, 3 had confirmed cases. Number of cases was highest among 21 - 30 years old, Male to female ratio among cases was 2:1 (16:8) and male to female ratio among confirmed cases is 3:1 (6:2). Twenty-five suspected cases and 187 contacts were line listed. There were 8 laboratory-confirmed cases and 2 deaths (case fatality rate of 25%) between 25th November 2016 and 16th January 2017. There was no evidence of epidemiological linkage among cases. Open display of farm produce and consumption of rats are a common practice in all communities in the state.
it was a confirmed outbreak of LF. We supported the state Ministry of Health in community mobilization and sensitization on prevention and control of LF. Health care workers were sensitized on infection prevention and control. The health department implemented these recommendations, which resulted in the control of the outbreak.
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.
