The detection of TBEV in the United Kingdom is important because TBEV can infect humans, causing febrile illness and neurologic complications including encephalitis. (medscape.com)
However, in addition to climate change, the spread of the tick vector, TBEV, and associated viruses into new regions can be influenced by a variety of other factors, such as transportation of animals and alterations in land management. (medscape.com)
[ 30 ] The hypothesis that TBEV infection might be maintained in Thetford Forest is supported by previous work in the United Kingdom that provided evidence of co-feeding between ticks from different life stages on small mammals in a southern English woodland, which is a crucial factor for the maintenance of TBEV. (medscape.com)
The genomic sequence of TBEV-UK shows close identity to a TBEV-Eu virus isolated in 2009 from questing ticks collected in Norway. (medscape.com)
This similarity suggests that TBEV-UK might have been brought to the United Kingdom on migratory birds, such as blackbirds ( Turdus merula ) and redwings ( Turdus iliacus ), [ 33 ] which are known to transport ticks over wide distances. (medscape.com)
During this migration, birds first arrive on the east coast of the United Kingdom, and it is feasible that TBEV-UK could have originated from a tick imported by an autumn migratory bird. (medscape.com)
We are collecting tick samples from migratory birds to assess the proportion of tick-infested birds arriving in the United Kingdom and testing these imported ticks for TBEV (among other potential pathogens). (medscape.com)
