Objective:
COVID-19 diverted health system resources from tuberculosis (TB) control, potentially increasing occupational TB exposure among healthcare workers. This study examined associations between COVID-19-related reprioritisation and self-reported occupational TB exposure.
Methods:
A retrospective cross-sectional study using self-reported data was conducted in public health facilities in 2022. A questionnaire assessed occupational TB exposure, service disruptions, and resource reallocation before and during COVID-19. Descriptive statistics and exploratory logistic regression were performed.
Results:
Self-reported TB cases declined during COVID-19, while occupational exposure remained high (79.0% peri-COVID-19 vs 80.0% pre-COVID-19). Many respondents reported TB budget reallocation (81.9%), GeneXpert reassignment (61.3%), inadequate PPE (63.1%), and treatment stock-outs (31.1%). No statistically significant associations were identified.
Conclusion:
COVID-19 reprioritisation may have reduced TB visibility through diagnostic disruption rather than exposure, highlighting the need to protect HCWs during health system shocks.

Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
