Hypothesis

What is the prevalence of latent tuberculosis infection (LTBI) among healthcare workers in Laos?

Conclusion

A significant proportion of healthcare workers in Laos have latent tuberculosis infection, and many are unaware of their TB status.

Supporting Evidence

  • 10.2% of healthcare workers tested positive for latent tuberculosis infection.
  • None of the participants were aware of their TB status.
  • Knowledge and awareness of TB and LTBI among participants were low.

Takeaway

Many healthcare workers in Laos have a hidden infection called latent tuberculosis, which they don't know about, and this can be dangerous.

Methodology

A cross-sectional study was conducted with healthcare workers from three central hospitals in Vientiane, using IGRA blood tests and questionnaires.

Limitations

The small sample size limits the ability to generalize findings to other settings in Laos.
