ClinConnect Summary

This clinical trial is looking into how many students who are in close contact with active tuberculosis (TB) patients have a latent TB infection, which means they carry the bacteria but do not show symptoms. The study aims to find out the percentage of these infections among school contacts, identify factors that might increase the risk of getting TB, and evaluate the costs of different screening methods.

To participate, you need to be at least 13 years old and a student in junior high school, high school, or university. It's important that you have been in close contact with someone diagnosed with active TB, like being in the same classroom or dormitory. If you join, you'll help researchers understand more about TB in schools, and you’ll need to agree to participate with your guardian if you are under 18. The study is currently recruiting participants, and those who are already being treated for active TB or have completed treatment for TB will not be eligible.
