  3. ‡ The number represents both in and out of country migrants and those applicants who were staying over 12 months and submitted full medical. Applicants who may have been screened with only a CXR and no medical (those people from high-incidence countries who are staying for more than 6 months but less than a year) would not have been included and the 279 represents the number of people who were defined as having an unacceptable standard of health out of the people who submitted full medical certificates likely to mean they had TB however this data was not available.
