Data for: "Travel and tuberculosis in migrants" – Data codebook

Permanent identifier

10.17037/DATA.00003534

Description

Tuberculosis (TB) rates among migrants are higher than local rates in low-incidence countries. This study evaluated smear-positive, pulmonary TB notifications of foreign-born individuals, comparing time since arrival and time since last return travel to the country of origin. The dataset contains notification data that was routinely collected within the TB service at the Department of Respiratory Medicine at Homerton Healthcare NHS Foundation Trust between 1996 and 2018 and audited to improve early diagnosis and access to health care.
