Lassa fever (LF) is a highly infectious haemorrhagic disease associated with
high morbidity and mortality. Health facility spread of infection is common
especially in settings with poor infection prevention and control practices.
In December 2016, a LF outbreak was reported in a tertiary health facility
in Ogun State which involved the death of a health worker. A team of Epidemiologists
was deployed to investigate the outbreak and institute appropriate control
we defined suspected, probable and confirmed cases using the national guidelines for integrated disease surveillance and response (IDSR). We conducted active case search and environmental assessment in 10 health facilities. Contact tracing was implemented, hospital and mortuary records were reviewed and line-list developed. We assessed Infection Prevention and Control (IPC) practices using a standard IPC checklist. Data were analyzed using Epi info version 7.2. Nineteen blood samples were collected from 14 cases and 5 high-risk contacts for virology.
all tested negative for Lassa fever virus except the first index case. We traced 3 probable cases and were able to link the confirmed case to hospital exposure. Case Fatality Rate was 100% among confirmed cases. Of the 345 contacts line-listed, 314 (89.5%) were health workers, out of which, 296 (94.5%) reported regular hand washing, 47 (15%) and 100 b (32%) reported uninterrupted water supply and availability of soap respectively. IPC practices, especially waste management in the hospital was poor.
investigation revealed a confirmed Lassa fever outbreak with a 100% Case
Fatality Rate. Source of infection strongly indicative of being hospital
acquired. Infection prevention and Control practices were sub-optimal. We supported
tracing to prevent further spread, conducted trainings and sensitization
to improve infection control and instituted control measures.
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.
