TB among health care workers
Among the 1,313 HCWs whose records were included
in the analysis, 112 (9%) cases of TB were identified during
the five-year period of interest. A greater proportion
of HCWs 20% (n = 14) that worked in a TB ward had
TB compared with HCWs without a history of working
in a TB ward 8% (n = 98) (p < 0.01). HCWs who worked
in one ward were less likely to develop TB 8% (n = 83)
than those who worked in more than one ward 15%
(n = 29) (p < 0.01). Among HCWs diagnosed with TB,
the largest category 48% (n = 53) were clinical staff
(all nursing staff ) followed by support staff 33% (n =
36), and female 70% (n = 78). Of the 112 cases of TB
28 (25%) did not have information on type of TB recorded
in their chart. Table 2 describes TB cases
among HCWs who had type of TB (drug-susceptible
or drug-resistant) documented in their chart (n = 84).
Fourteen (13%) HCWs had drug-resistant TB, among
which 13 (93%) had MDR-TB and 1 (7%) XDR-TB.
