Parvovirus B19 infectious rheumatism

Parvovirus B19 is a new virus that has been gradually recognized recently. As early as 1975, Yvonne Cossart was the first to identify a microviral particle in the serum of a HBsAg control labeled B19 and found it to be a different antigen from HBsAg. After electron microscopy, the serum containing this antigen was recognized as a spherical particle and a typical viral enzyme shell. This new virus was originally found in the serum of healthy blood donors. Its antigen has a suspension density of 1.36 to 1.40 during cesium chloride gradient electrophoresis and is a typical microviral enzyme. In 1985 they studied the pathogenic effects of the virus. It has been confirmed that parvovirus B19 can cause rheumatism.
