T2-weighted sequences, limited to the anterior horn region throughout the spinal cord, without enhancement with gadolinium (Figure 1). The Department of Human Services, Victoria, was notified of the clinical diagnosis of poliomyelitis; the patient was admitted to a single room, and contact precautions were instituted.
VP1 phylogenetic tree constructed by using cognate sequence available in the public domain was created by using the PHYLIP DNA maximum-likelihood algorithm with 100 bootstrap replicates. Marker represents relative phylogenetic distance. AFG, Afghanistan; AUS, Australia; BAN, Bangladesh; CHN, China; GRE, Greece; IND, India; IRA, Iran; NEP, Nepal; PAK, Pakistan; SYR, Syria; TAJ, Tajikistan; UZB, Uzbekistan. Scale bar represents number of nucleotide substitutions per site.

Phylogenetic analysis showed a common ancestor with a wild poliovirus isolated from Pakistan in 2000 and clustering within a group of isolates originating in Pakistan, Afghanistan, and Iran (Figure 2).
