In TB contact tracing, which group is prioritized as the highest risk?

In TB contact tracing, household members are prioritized as the highest risk group due to their close and prolonged exposure to the infected individual. The dynamics of living in the same household facilitate the transmission of tuberculosis, as members often share air, spaces, and daily activities, which increases the likelihood of infection.

Additionally, household contacts typically have a higher frequency of interaction with the infected person compared to other contacts. This consistent exposure means that if the infected individual is not treated promptly, the risk of spreading the disease to family members is significantly heightened.

While other groups such as transportation contacts or workplace contacts are also at risk, the nature of household relationships and the constant close proximity make household members the top priority in contact tracing efforts. Therefore, identifying and assessing the health of household members is critical in controlling the spread of TB within communities.
