Introduction: a new swine disease in the United States is attracting the attention of pig breeders and industry experts Weaned piglets with multiple system failure syndrome (PMWS) are mainly infected with PCV2 for 6 to 14 weeks Infected piglets grow slowly, have difficulty in breathing, have diarrhea and jaundice, and those with serious illness will die Steve sorden, a veterinary pathologist at Iowa State University's veterinary diagnostic laboratory, said the virus is common and is found all over the country However, most pigs are not infected even if they are exposed to the virus In the laboratory, PCV2 can only be found in 10% of cases of swine pneumonia, he said He added that the virus was found in the tissue culture archive of the University of Iowa, dating back to 1993 So far, the USDA has not found the transmission pathway of weaning pig multiple system failure syndrome (PMWS) in the United States, because the USDA has not been able to get enough timely and accurate information from the ongoing cases However, in a recent Reuters article, British scientists reported that the virus had an infection rate of about 40% in young pigs This year, it said, 300000 piglets could be lost on British farms.
