Key result
Small home size, well water use, and age ≥15 years were risk factors for death during a 2010 polio outbreak, with nonsurvivors being older than survivors (median age 22 vs 18 years, P=0.01).
Observational (n=369)
p-value: p=.01
Older age, small home size, and well water use were associated with higher mortality during a wild poliovirus outbreak in the Republic of Congo.
No takes yet. Share an insight, caveat, or question.
May warrant closer monitoring of older patients in outbreaks; leaves open validation of household risks in prospective studies.
Gregory et al. (2012) conducted an observational in Poliomyelitis (n=369). Small home size, well water use, and age ≥15 years vs. Absence of these risk factors was evaluated on Fatal outcomes (p=.01). Small home size, well water use, and age ≥15 years were risk factors for death during a 2010 polio outbreak, with nonsurvivors being older than survivors (median age 22 vs 18 years, P=0.01).
