a Haemorrhagic Fever with Renal Syndrome(HFRS: later renamed hantavirus disease, HVD)first recognized in Heilongjiang, China in the 1930s, and came to the attention of the West during the Korean war when over 3000 UN troops were afflicted It transpired that the disease was not new and had been described by the Chinese 1000 years earlier In 1974, the causative was isolated from the Korean Stripped field mice and was called Hantaan virus In 1995, a new disease entity called hantavirus pulmonary syndrome was described in the"four corners" region of the U.s

根据抗原和基因结构分型(10型) Hantaan(汉滩型) Porrogia and related viruses -This group is found in China, Eastern USSR, and some parts of S. Europe. it is responsible for the severe classical type of hantavirus disease. It is carried by stripped field mice Apodemus agrarius Seoul type(汉城型) e associated with moderate hantavirus disease. It is carried by rats and have a worldwide distribution. It has been identified in China, Japan, Westem USSR. USA and S america Puumala type mainly found in Scandinavian countries, France, UK and the Western It is carried by bank voles( Clethrionomys glareolus)and causes mild hantavirus disease(nephropathia epidemica) Sin Nombre(辛诺柏型) found in many parts of the US, Canada and Mexico. Carried by the Deer Mouse( Peromyscus maniculatus)and causes hantavirus pulmonary syndrome
