“…Our finding that refugee and live-in caregiver classes had some of the highest TB rates among people migrating to BC complements previous Canadian findings. 3 Our study further adds to this recent cohort study reporting 2-year TB incidence among people migrating to Ontario 3 by including a longer follow-up time to assess TB incidence rates across years since immigration, by using MSP records to estimate time spent in province, by including a more detailed breakdown of immigration classes and by using recursive partitioning methods to determine the groups at highest risk of TB after immigration.…”

A s tuberculosis (TB) transmission declines in regions of low TB incidence, TB is becoming concentrated in migrant populations.1 In Canada, a country with low TB incidence, most cases of TB (about 70%) are diagnosed in people born outside of Canada, with many arriving from countries with a high TB incidence. 2Preimmigration medical screening is a cornerstone of TB prevention in Canada. Prospective permanent residents and temporary residents who will be staying in Canada for more than 6 months undergo a preimmigration medical examination that includes a history, physical examination and chest radiograph, and when indicated by radiograph abnormalities, sputum samples for smear and culture. Applicants with a diagnosis of active TB must receive treatment before they can obtain residency status.2 Postimmigration surveillance of select individuals is also conducted, whereby people considered to be at high risk for TB (i.e., evidence of prior TB or abnormalities present on chest radiographs) are highlighted for follow-up surveillance by public health authorities in Canada.2 However, a recent study found that less than 3% of active cases of TB in people migrating to Canada were detected by postimmigration surveillance.3 Currently, no routine pre-or postimmigration screening and treatment programs for latent TB infection (LTBI) for people migrating to Canada are available. Scale-up of LTBI screening and treatment in high-risk populations postimmigration is a component strategy for achieving World Health Organization (WHO) targets for TB elimination in Canada.4,5 However, with about 250 000 new permanent residents migrating to Canada annually, the large population of people who may qualify for LTBI screening and treatment is a substantial barrier to implementation.6 National guidelines recommend targeting screening for LTBI in people migrating from high-incidence countries, particularly in adult refugees up to 50 years of age and those with other risk factors for increased TB reactivation.2,4 However, many of these recommendations are based on weak evidence.

“…La surveillance post-immigration des immigrants sélectionnés et considérés comme présentant un risque élevé de développer une tuberculose active dépend également de certains facteurs de risque identifiés lors de l'examen médical réglementaire (7). L'objectif de l'examen médical réglementaire est de s'assurer que les migrants atteints de tuberculose active sont diagnostiqués et traités, et qu'ils ne sont plus contagieux avant leur arrivée au Canada.…”

Tuberculosis (TB) is the leading cause of infectious mortality in the world, affecting mainly developing countries (DC), while diabetes (DM) is one of the most prevalent chronic diseases. This review analyzes the fact that diabetes is currently an important risk factor for developing TB, also presenting more complicated TB, more relapses and higher mortality. The DCs and the fourth world of the large cities are those with the highest incidence of TB and an increase in DM, which will make it difficult to control tuberculosis disease. At the same time, the COVID-19 pandemic is complicating the management of both diseases due to the difficulty of access to control and treatment and the worsening of socioeconomic inequalities. It is necessary to establish a bidirectional screening for TB and DM and promote recommendations for the joint management of both diseases.
