Philippines - Atypical PRRS virus

The OIE has informed about the presence of atypical PRRS virus in the district of Sto Nino (Pandi municipality, Bulacan province) and in the district of Pinagpanaan (Talavera municipality, Nueva Ecija province). Samples from the outbreaks were sent to the USDA Plum Island laboratory. Results show that samples were positive for porcine circovirus type 2 and atypical PRRS virus, which is 98% homologous to the atypical PRRS virus isolated in China and Vietnam. With high morbidity and mortality observed similar to China and Vietnam, it was concluded that these outbreaks were most likely caused by atypical PRRS virus.
