Summary
Tula hantavirus (TULV) was detected in European common voles in Belgium, marking the first evidence of this virus in the country. This finding suggests TULV is more widespread across Europe than previously understood.
Area of Science:
- Virology
- Zoonotic Diseases
- Mammalian Ecology
Background:
- Tula hantavirus (TULV) is a known hantavirus serotype circulating in Europe.
- European common voles (Microtus arvalis) are potential reservoirs for hantaviruses.
- Puumala virus is endemic in bank voles (Clethrionomys glareolus) in similar regions.
Purpose of the Study:
- To investigate the presence of Tula hantavirus (TULV) in European common voles in Belgium.
- To determine if spill-over infections of Puumala virus occurred in the studied population.
Main Methods:
- Molecular techniques (e.g., PCR) were used for viral detection.
- Serological assays were employed to confirm infections.
- Rodent trapping and sampling were conducted in Belgium.
Main Results:
- Tula hantavirus (TULV) infection was confirmed in European common voles captured in Belgium.
- This represents the first documented evidence of TULV in Belgium.
- No evidence of Puumala virus spill-over infection was found in the common vole population.
Conclusions:
- The study confirms the presence of Tula hantavirus (TULV) in Belgium.
- The findings indicate a broader circulation of TULV across the European continent.
- Further surveillance is warranted to understand the epidemiology of TULV in common voles.
