pertussis or whooping cough, though vaccine-preventable, has remained a public health threat despite the availability of vaccine. In May 2016, we investigated a pertussis outbreak in Gidan Kanawa and Ungwar Yamma settlements in Kano State, North-West Nigeria to characterize the outbreak and determine its associated factors.
we conducted an unmatched case-control study with ratio 1:1. A case was defined
as any person < 10 years in Gidan Kanawa and Ungwar Yamma settlements with a-cough
lasting up to 2 weeks with paroxysmal or whooping cough with/without vomiting;
while a control was any person < 10 years in the neighborhood without cough.
Data was collected on socio-demographic characteristics, immunization history
and probable risk factors using a semi-structured questionnaire. We calculated
frequencies and proportions to characterize the outbreak in time, place and
person. We conducted bivariate and multivariate analyses to identify factors
associated with the outbreak. Ten oropharyngeal swabs were taken from cases
for culture in the laboratory.
a total of 83 cases were line listed, 43 (52.5%) were males. Median age of cases was 36 months (range 2 - 108 months) with case fatality rate of 9.7%. The attack rates were 1.92% in Ungwar Yamma and 22.1% in Gidan Kanawa. Among cases, the drop-out rate for pentavalent vaccine was 33.3% while 61 (59.8%) were zero dose for pentavalent vaccine in both settlements. The independent factors associated with pertussis, were concerned with the contact with cases (Adjusted Odds Ratio, AOR 4.5; 95% CI = 2.2 - 9.5) while the history of complete pentavalent vaccination (AOR = 0.3, 95% CI = 0.1 - 0.8) was protective. Laboratory results were inconclusive.
the major determinants of the outbreak were concerned with the contact with cases and having zero or no dose of pentavalent vaccine. Cases were managed with antibiotics and supportive treatment. We recommended immediate vaccination of contacts.
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.
