Researchers confirm six unique strains of African swine fever virus

The U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) has announced that researchers have reclassified the number of African Swine Fever (ASF) virus strains from 25 to only six unique genotypes. This scientific innovation may help redefine how ASF researchers across the globe classify ASF virus (ASFV) isolates and may make it easier for scientists to develop vaccines that match the different strains circulating in ASF endemic areas across the globe.
