Porcine circovirus disease (PCVD) is a generic term for a variety of clinical diseases caused by porcine circovirus type 2 (PCV2) infection, a new infectious virus that causes enormous economic losses to the global pig industry each year. Currently known vaccination is the main method of effective prevention and treatment of this disease, but clinically, due to the different health status of pigs, other pathogenic microorganisms associated with infection, feeding environment changes in the clinical PCVD control there are still many difficulties. The article discusses the PCV2 infection to the pigs caused by the disease, the clinical and laboratory diagnosis of the disease, the virus and the widespread use of vaccines emerging problems. .
