View Article: PubMed Central - PubMed

ABSTRACT

Polio seroprevalence surveys help measure progress towards polio eradication.

Nigeria program conducted multiple seroprevalence surveys in northern states.

This article covers seroprevalence survey in Kano Nigeria in 2013 and 2014.

Data represents levels before and after the interruption of poliovirus transmission.

Significant improvement in seroprevalence in 2014 over 2013, but gaps continue.

Good participation even by vaccine refusers in this health facility based project.

Seroprevalence and 95% confidence intervals, by poliovirus serotype in 6–9 month old cohort in 2013 and 19–22 month old cohort in 2014.

f0005: Seroprevalence and 95% confidence intervals, by poliovirus serotype in 6–9 month old cohort in 2013 and 19–22 month old cohort in 2014.

Mentions: Comparison of the seroprevalence levels for the 6–9 month cohort of 2013 becoming 19–22 months old in the 2014 survey; is shown in Fig. 1. An increase in seroprevalence to the tune of 23%, 16% and 27% was seen for the three poliovirus types: from 58% for infants 6–9 months old in 2013 to 81% for children 19–22 months old in 2014 (95% CI 75–87%) for type 1 (p < 0.001), from 41% to 57% (95% CI 50–64%) for type 2 (p = 0.004), and from 52% to 79% (95% CI 72–84%) for type 3 (p < 0.001). Even in 2014, type 2 seroprevalence remained low (approximately 60%), and was similar for both the 6–9 month and 19–22 month age groups.
