Tuberculosis among health-care workers

<b>Introduction:</b> The risk of TB transmission in health-care facilities is high. The ratio of the TB notification rate for health-care workers (HCW) and general adult population is a good indicator of the impact of TB infection control in health facilities (WHO, 2016),&nbsp;at the same time TB infection control is one of the key components of the second pillar of the End TB Strategy. Moreover the indicator is useful for assessment of TB control effectiveness in region with relatively low TB incidence. <b>Methods:</b> Analysis included TB surveillance data about all 350 new TB patients registered among HCW in 2016-2020, who were employee of health facilities located on Moscow city territory. <b>Results:</b> Residents and non-residents (internal and external migrants) accounted for 61.4 % and 38.6% of TB cases among HCW, respectively. Employee of state facilities accounted for 62.6% of cases and of private facilities accounted for 37.4% cases. TB patients from HCW included 34,6% doctors, the same share (34,6%) of nursing staff, 5.7% paramedical and 25,1% non-medical staff. Targeted activities for TB control among HCW led to increase of share of TB detection by screening (active detection) form 74-79% in 2016-2017 to 80.9% in 2020. As result of early TB detection among these population, the share of disseminated pulmonary TB cases in HCWs is significant less, then in total Moscow population: 5.4% (95%CI 3.3-8.3%) and 20.6% (19.9-21.5%), respectively (p &lt; 0.01). Five years average TB notification rate in HCW is 35.0 that only in 1.3 more than TB notification rate for general adult Moscow population (27.6 per 100 K). <b>Conclusions:</b> TB surveillance in HCW reflects relatively safe TB epidemiology and satisfactory TB infection control in health facilities in Moscow.
