viral hemorrhagic fever is a generic term for a severe illness, often accompanied by bleeding and caused by viruses. Lassa fever is a viral hemorrhagic fever caused by Lassa Virus of the family Arenaviridae. Lassa fever is endemic in Nigeria especially Edo State with zero-prevalence of 21% and 28% mortality. The aim of this study was to evaluate the laboratory based surveillance system for Lassa fever to assess its key attributes and whether it meets its objectives.
an evaluation of the laboratory based Lassa fever surveillance system was
carried out at the Institute of Lassa Fever Research and Control (ILFRC), Irrua
Specialist Teaching Hospital, Irrua, Edo State from 2013 to 2015. The evaluation
was conducted using the CDCís updated guidelines for evaluating public health
surveillance system, 2001. The methods included interview of stakeholders and
review of documents. Relevant stakeholders were identified and interviewed to
obtain their input in describing the system and assessing key attributes of
the system. Documents relevant to the surveillance of Lassa fever in Nigeria
were also reviewed.
out of 3,268 suspected cases screened for Lassa fever from 2013 to 2015, 308 were laboratory confirmed as Lassa fever. The predictive value positive was 9.4%. The case definition for Lassa fever surveillance is simple and easy to apply. The system integrates well with the Integrated Disease Surveillance and Response (IDSR) system and is representative. The system is flexible as data is also being collected on malaria fever. Data incompleteness for all variables ranged from 7% to 11%. The system is also useful. Stakeholders interviewed agreed that effective Lassa fever surveillance ensured the control and elimination of Lassa fever.
Lassa fever surveillance system in ILFRC is meeting its objectives of detecting
and controlling the disease in Nigeria. However, the surveillance system has
gaps in terms of data quality and completeness. Government should provide more
funding and support to the system.
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.
