The study maps the endemic circulation and regional transmission of type 1 polioviruses throughout sub-Saharan Africa, identifying seven distinct genotypes.
Chezzi et al. (1997) conducted an observational in Type 1 poliovirus infection. Type 1 poliovirus genotypes was evaluated on Genetic relationships and geographical distribution of type 1 polioviruses. Seven type 1 poliovirus genotypes were identified circulating in sub-Saharan Africa, with two major genotypes currently circulating and evidence of endemic transmission and imported strains.
