A purity separation and refining method of the virus from the infectious blood is provided to easily separate and refine the virus from the blood of human or animal, thereby facilitating the development of infectious virus separating and refining kit, and production of antibody. The virus, porcine circovirus type 2(PCV2) is separated and refined from the infectious blood of human or animal through the filtration by using celite, clarification of host material and impurities by using organic solvent, virus concentration by using polyethylene glycol(PEG) as water-soluble precipitation supplement, and the virus fractionation by using sucrose density gradient centrifugation.
