Cause?
“Transportation of the virus by midges is believed to have occurred on a Southeasterly wind from the continent.
Thetford has been selected as a centre point of East Anglia and the centre point of the range rings that are spaced 20km apart.
As the map shows spread of the virus is greatly affected by climatic conditions such as wind and temperature.
As wind direction is a significant factor in the spread of the virus, winds from the Northeast and Southeast quadrants pose the greatest risk of the virus spreading, along with a mild winter.
DEFRA control zones could very well change on a daily basis so farmers are well advised to check with DEFRA on the latest situation.
Please check the map (gets updated).
