Canadian Border Security (CBSA) Practice Exam

What could indicate that someone might present a danger to public health?

1. Recent immigration applications

2. Criminal history related to violence

3. Contagious diseases or unmanaged health issues

4. Not holding a valid visa

The correct answer is: Contagious diseases or unmanaged health issues

The correct choice highlights the significant impact that contagious diseases or unmanaged health issues can have on public health. Individuals carrying infectious diseases pose a direct threat to the wider community, as these conditions can be transmitted to others, leading to potential outbreaks. Furthermore, unmanaged health issues might suggest that a person is not receiving necessary medical care, which can exacerbate public health risks. Recent immigration applications and not holding a valid visa may indicate legal or procedural issues but do not inherently suggest a threat to public health. Similarly, while a criminal history related to violence could raise concerns for safety, it does not directly correlate with health risks in the same way that contagious diseases do. Thus, the presence of health-related issues that are infectious or unmanaged is the most relevant indicator of potential danger to public health.
