An improved sewage surveillance algorithm (sample acquisition, processing, and molecular analysis) for wild and vaccine-derived polioviruses was developed and validated. It was based on plaque isolation with sensitive and high-throughput methods. The molecular analysis included sequencing; a comparison of the type, rate, and distribution of nucleotide substitutions with a profile for outbreaks evolving from a single progenitor; and phylogenetic analysis for relative similarity. The analyses revealed that two environmental wild type 1 isolates from the Gaza district in 2002 were imported separately, most likely from Egyptian southern governorates, and were not linked by endemic circulation. These findings illustrate the continuous spreading potential of wild-type poliovirus and underscore the value of extensive environmental surveillance employing advanced molecular analysis to monitor wild poliovirus in poliomyelitis-free regions.
