Incidence of TB in UK Cattle - August 2009

19 August 2009

UK - The provisional April 2008 estimate lies below the incidence rate for April 2007.

However, care needs to be taken not to read too much into a single month's figure, especially as this figure includes a high number of unclassified incidents. As such the incidence rates are subject to further revisions as more tests and their results are input.

Provisional statistics show a 1.4 per cent decrease in the number of new TB incidents in January - May 2009 compared to the same period in 2008. Combined with an increase in the number of herds tested over the same period, this equates to a provisional overall decrease in the TB incidence rate (new TB incidents, as a proportion of tests on unrestricted herds) of 7.1 per cent.

The provisional average confirmed incidence rate (confirmed new TB incidents, as a proportion of tests on unrestricted herds) was 4.1 per cent for January - May 2009, compared to 5.0 per cent for the same period in 2008.
