Key result
Residence in the Jordan Valley was associated with lower seroprevalence for poliovirus type 3 after 5 doses of OPV compared to other regions (77% vs 98%, P<0.001).
Why the study?
What were the OPV coverage and seroprevalence rates during the 1991-1992 poliomyelitis outbreak in Jordan?
Population
37 patients with paralytic poliomyelitis and 987 children in a seroepidemiologic study in Jordan
Design
Cross-sectional

Geographic seroprevalence gaps may signal need for targeted polio surveillance; leaves open whether regional factors affect OPV response.
Cross-Sectional (n=987)
Yes
What were the OPV coverage and seroprevalence rates during the 1991-1992 poliomyelitis outbreak in Jordan?
Absolute Event Rate: 77% vs 98%
p-value: p=< .001
The outbreak highlights the need for high seroimmunity across all geographic areas and subpopulations to prevent wild poliovirus spread.
Reichler et al. (1997) conducted a cross-sectional in Paralytic poliomyelitis (n=987). Residence in the Jordan Valley vs. Residence in other regions of Jordan was evaluated on Seroprevalence for poliovirus type 3 after 5 doses of OPV (p=< .001). Residence in the Jordan Valley was associated with lower seroprevalence for poliovirus type 3 after 5 doses of OPV compared to other regions (77% vs 98%, P<0.001).
