Testing for latent tuberculosis infection needs to be improved in Denmark

: Tuberculosis (TB) remains a public health emergency worldwide. WHO recommends low-incidence countries to increase awareness of latent tuberculosis infection (LTBI) as part of a national preventive strategy. This review focuses on the burden of TB in Denmark, which might be reduced, if more focus was paid on diagnosing LTBI in relevant patients, and treatment to prevent future active TB cases was initiated. LTBI testing should be considered in persons at risk of TB disease, who will benefit from LTBI treatment, e.g. recently infected persons or persons having undergone organ transplantation or having comorbidity such as HIV, dialyses, and immunosuppression.
