Which of the following is a challenge to TB eradication?

One significant challenge to tuberculosis (TB) eradication involves the risk associated with the movement of infected individuals and animals across borders, which can perpetuate the spread of the disease. In particular, the importation of Mexican cattle and the potential for interaction with infected humans heighten the transmission risk. This zoontic aspect of TB, coupled with the human-to-human transmission potential, complicates effective control measures.

Understanding how TB can be spread through both human and animal populations underscores the need for comprehensive public health strategies that address various pathways of transmission. This challenge emphasizes the interconnectedness of health systems and the importance of monitoring and controlling TB not only within human populations but also in relation to livestock and animal health.
