[Hantaviruses in Germany: threat for zoo, pet, companion and farm animals?].

Hantaviruses are so-called "emerging" and "re-emerging" viruses because of the new and sudden nature of their appearance. Human infections can lead to two distinct disease patterns, the Haemorrhagic Fever with Renal Syndrome and the Hantavirus Cardiopulmonary Syndrome. All known human pathogenic hantaviruses are transmitted through rodent hosts. There are three rodent-associated hantaviruses in Germany. The bank vole-associated Puumala virus (PUUV) is responsible for most of the human hantavirus infections. The Dobrava-Belgrade virus (DOBV) associated with the striped field mouse is causing hantavirus disease in the North and Northeast of Germany. The human pathogenicity of Tula virus (TULV) is still controversially discussed--the virus has been mainly associated with the common vole as the reservoir, but was molecularly detected also in the field and the water vole. More recently, two shrew-borne hantaviruses were described in Germany, i. e. Seewis virus in the common shrew and Asikkala virus in the pygmy shrew. Systematic studies about hantavirus infections of zoo, pet, companion and farm animals are still lacking. Hence, the aim of this review article is to summarise the current knowledge on this topic and raise the attention of veterinarians to potentially overlooked clinical disease patterns.
