Are you surprised by the arrival of the bluetongue virus?
Bluetongue has been expected for a long time, partly for the wrong reason. The midge which has transmitted it around the Mediterranean is very temperature-dependent and was moving northwards so, in the fullness of time with global warming, it was expected to arrive, bringing Bluetongue with it. In fact the virus we have is not the same as that occurring in southern Europe - there are unanswered questions about this.
Will our winter kill it off?
The crucial factor will be temperature - it needs an average temperature of 12C year-round. We are not absolutely certain if it is a question of the midges surviving or the virus surviving in infected animals and in doing so harbouring a reservoir of virus for midges the next year.The answers were given by Prof. Hugh PenningtonThis statement gives the impression that C. Imicola is involved in BTV 8 transmission in the UK. I should be grateful to learn whether recent vector surveys have shown the presence of C. Imicola in the outbreak regions.08.11.2007Standing Committee on the Food Chain and Animal Health (SCFCAH)Meeting 6/7.
