Lassa fever (LF) is an epidemic-prone viral haemorrhagic disease caused by
the Lassa virus. However, prompt patientsí isolation, good infection control
practices and contact tracing are important in outbreak control. On January
8, 2016, the Nigeria Federal Ministry of Health was alerted of an ongoing outbreak
of Lassa fever across states including Edo State. We investigated to establish
the existence of the outbreak, contact tracing, monitoring, described the outbreak
and assessed infection control measures in Edo State.
we did a descriptive study of confirmed LF cases of Edo State from 23rd December 2015 to February 2016. Active contact tracing and laboratory surveillance were used to detect suspected and confirmed Lassa fever cases. Infection prevention and control checklist was used to assess infection control of the Lassa fever institute isolation ward. Patientsí bio-data were collected from structured questionnaires applied on patientís relatives, Lassa fever laboratory register and survey forms. Data was analyzed with Epi Info 7 and the outbreak described by person, place and time. Univariate analysis was expressed as frequency distribution, percentages, median, interquartile range and rate.
a total of 359 suspected cases were screened of which 29 (8%) tested positive
for Lassa virus. Case fatality rate was 9 (31%). The median age of cases was
30 years (IQR = 25 - 47), 17 (58.6%) were males, and 13 (44.8%) were students.
Ten LGAs were affected including Etsako West LGA 12 (41%) of cases. During the
outbreak period, 179 contacts were monitored. Clinical presentations included
redness of the eyes (79%), haematuria (69%), and facial oedema (52%). Infection
control assessment of 15 items revealed 7 (46.7%) not available in the isolation
good infection prevention and control at the isolation ward challenged by an initial unavailability of some infection control items. Active contact tracing, prompt patientsí isolation, and surveillance helped in control and detection of the outbreak. Continuous community awareness, good infection control practices, and active surveillance may prevent and detect early outbreaks.
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.
