Tuberculosis contact investigation in an intermediate burden setting: implications from a large tuberculosis contact cohort in Taiwan
نویسندگان
چکیده
There are still several unanswered research questions regarding tuberculosis (TB) contact investigations [1–4]. For example, up-to-date epidemiological studies regarding TB contacts in the area of intermediate incidence are not readily available [5]. The long-term risk of TB, especially beyond 5 years, remains undetermined [6]. Risk factors for TB development among contacts are also not well defined [2]. To expand current understanding and knowledge of TB contact investigation, we recruited a population-based TB contacts cohort utilising the National Health Insurance Research Database of Taiwan, which included medical care claims data of 99% Taiwan residents [7].
