Geographically, this specimen probably is more nearly a topotype than any other examined. |
Prior to 1999, one group of SEA topotype viruses occurred in the eastern part of the region and another group in the western part. |
Both of isolates belong to the Sea-97 genotype of ASIA topotype. |
The Cathay topotype was reported from Vietnam in 1997 and is the only FMD virus currently endemic in the Philippines. |
