6 Distribución geográfica

Se han establecido dos genotipos (tipo 1 o Europeo y tipo 2 o Americano). En Europa predomina el tipo 1 mientras que en América y Asia el más prevalente es el tipo 2.

Actualmente, están clasificados como dos especies víricas diferentes: PRRSV1 y PRRSV2. Dentro del PRRSV1 se han descrito al menos 4 subtipos. El subtipo I es el más predominante en la Europa Occidental, mientras que los subtipos II, III y IV han sido aislados hasta la fecha solo en países más al Este de Polonia. Respecto al PRRSV2 se han descrito dos clados.

A pesar de todo ello, ambas especies se han diseminado por todo el mundo. Así, se pueden encontrar en casi la totalidad de países productores de cerdos, a excepción de Australia, Nueva Zelanda, Países Escandinavos, Suiza y algunos países de América del Sur.

El virus del PRRS altamente virulento que surgió en China pertenece al PRRSV2. Este se diseminó rápidamente por Asia. Actualmente se puede encontrar en el Este, Sur y Norte de Asia: Bután, Camboya, China, Indonesia, Laos, Malasia, Myanmar, Filipinas, Rusia, Singapur, Vietnam, etc. (World Organization for Animal Health; World Animal Health Information Database Interface; OIE 2013).

Tal y como puede deducirse del mapa sobre la distribución mundial del virus del PRRS, el riesgo de una transmisión intercontinental de cualquier cepa, incluyendo las cepas altamente virulentas detectadas en Asia, es muy real. Además, tal y como se ha podido observar en Chile, la reintroducción del virus en un país previamente libre puede ser devastador.
