Abstract

The newly identified tick-borne Alongshan virus (ALSV), a segmented Jingmen virus group flavivirus, was recently associated with human disease in China. We report the detection of ALSV RNA in Ixodes ricinus ticks in south-eastern Finland. Screening of sera from patients suspected for tick-borne encephalitis for Jingmen tick virus-like virus RNA and antibodies revealed no human cases. The presence of ALSV in common European ticks warrants further investigations on its role as a human pathogen.

Highlights

  • In 2010, a novel segmented tick-borne RNA virus, JMTV, was detected in Rhipicephalus microplus ticks in Hubei Province, China [3]

  • Similar viruses have been identified in R. microplus and cattle in Brazil, i.e. the Mogiana tick virus (MGTV) [4,5,6]; human CrimeanCongo haemorrhagic fever (CCHF) cases in Kosovo* [7]; Amblyomma javanense, Dermacentor silvarium and I. persulcatus ticks as well as humans in China [1]; and a red colobus monkey in Uganda [8]

  • Our findings show that Alongshan virus (ALSV), a newly described tickborne human pathogen, is present in southeastern Finland
