At the request of the Government of the United Kingdom, IOM implements the Tuberculosis (TB) Detection Programme for visa applicants who intend to stay in the UK for a period of 6 months or longer. The main purpose of the programme is to address public health concerns regarding the spread of infectious tuberculosis in the UK by preventing the entry of people suffering from active TB until they have been successfully treated, as well as to facilitate access to diagnostics and referrals for treatment in the migrants’ countries of origin.
