Most cases of TB arise form reactivation of latent TB amongst people who have been settled in the UK for more than two years but were born abroad in countries with a high TB burden.
Despite Wales having a relatively low prevalence of tuberculosis (TB) compared to other parts of the United Kingdom, the identification of healthy people with latent TB is an important strategy for the reduction of TB in Wales and primary care has an important role to play.
The management of TB cases, contact tracing and controlling outbreaks can place a significant demand on local services. TB cohort review was introduced into Wales in 2012 following an assessment of the North London cohort review process. It is a quality assurance process that improve TB case management and treatment completion.
