Suffix number refers to the poliovirus serotype (types 1, 2 or 3). 2. Source of specimens could be AFP cases, contacts, or non-AFP cases 3. Refers to year of last VDPV case, and aggregate total of VDPV cases for 2000-2009 4. Based on laboratory reporting only; not yet classified by AFP surveillance
