Numbers of new TB breakdowns have remained very low in the Low TB Area over many years. Yet, evidence has been emerging of an increasing number of new TB incidents in localised areas of the Low TB Area, known as TB hotspots. The key recent finding is that these new incidents have been locally linked. Measures are now needed to address this emerging issue.
We have introduced new measures in a phased approach between 1 June and November 2021. This is:
- in response to this emerging disease situation, and
- to protect the long-term health status of the Low TB Area
We have published details of these measures on Low TB Area: frequently asked questions.
On 1 November 2021, a temporary reclassification of the three Denbighshire/Conwy Valley spatial units CL1, CL2 and GW1. This is as part of the Intermediate TB Area North (ITBAN) from the Low TB Area.
This change has now been reflected in:
- Defra National Statistics, and
- our Bovine TB Epidemiological Dashboard
This change has affected the historical data in these outputs to provide trends over time of these new TB Areas. This means there has been:
- an increase in some measures in the Intermediate TB Area North, and
- a decrease in some metrics in the Low TB Area
following this temporary reclassification. The remaining TB Areas remain unaffected.
The tables below provide an illustrative example of what some 2021 Q3 measures would have looked like under the old TB Area boundaries compared with the new TB Area boundaries for the Intermediate TB Area North and Low TB Area which have been published in the latest dashboard.
