globally, Nigeria is one of the three polio endemic countries. Taraba State
reported two confirmed wild polio virus type 1 (WPV 1) cases between April -
May 2013. The cases were in settlements 2 - 3 kilometers apart. The state last
reported WPV 1 in 2008. We conducted an outbreak investigation of Poliomyelitis
to determine the factor(s) that contributed to the re-emergence of WPV 1 and
to assess the extent of spread of the cases.
we defined a paralytic polio case as any case of Acute Flaccid Paralysis (AFP) with wild polio isolation in stool from April - May 2013. We reviewed medical records in health-facilities to obtain information on reported AFP cases. We interviewed household heads of cases to obtain information on socio-demographics and immunization status of cases. We also conducted an immunization coverage survey in 30 households in each affected settlement.
a total of two AFP cases were identified in the affected Local Government Area (LGA) and all 2 (100%) were positive for WPV 1. All cases were males with a mean age of 15 months; both never received Oral Polio Vaccine (OPV). Seventy-four children were sampled during the survey, 33 (45%) males and 41 (55%) females with a mean age of 24 months. 53 (71%) never received OPV through Routine Immunization (RI) and attributed it to health-facility being inaccessible due to distance. Forty-one (55%) never received OPV (Zero-dose) during Supplemental Immunization Activities (SIA) and attributed it to SIA teams not visited the house. Affected settlements are contiguous farming settlements, with underserved Fulani settlements in the surroundings. Seventy-seven children in 15 surrounding settlements were vaccinated during mop-up vaccination. Settlements were not in ward micro-plans and missed during polio immunizations.
sub-optimal immunization coverage and gaps in surveillance are plausible factors for re- emergence of poliomyelitis. We carried out a rapid mop-up vaccination in the affected and contiguous settlements, conducted a large-scale mop-up immunization in the state and recruited key informants in the communities for AFP surveillance. We included affected settlements in the micro-plans and recommended conduct of outreach sessions by health facilities offering Routine Immunization to the affected and contiguous settlements.
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.
