Abstract

Health care workers (HCWs) are exposed to patients with tuberculosis (TB) and are at risk of nosocomial infection. Most of them acquire Mycobacterium tuberculosis but do not progress to the active disease- latent tuberculosis infection (LTBI). The objective of this study was to assess the prevalence and risk factors associated with LTBI among HCWs in Bach Mai Hospital. Methods: This cross-sectional study of HCWs was conducted from February to December in 2018. Participants (n = 794) were administered a questionnaire on demographics and occupational tuberculosis exposure and had a tuberculin skin test (TST) administered. Results: The overall prevalence of LTBI among HCWs was 44,1%. Factors significantly associated with LTBI were working duration in healthcare over one year [8.8(CI:1.14;69)]; worked as a nursing assistant [2,32(CI:1.16;4.64)], those who had no BCG vacccination in history [4.91(CI:3.52;6.88)] and recent history of contact to TB patients diagnosed TB without any protection measures [1.59(CI:1.12;2.02)]. Conclusions: The prevalence of LTBI in Bach Mai hospital was high. Adequate infection control measures are warranted to prevent and control transmission in health care settings.
