If a migrant group moves from an area with a low incidence of a particular disease to an area with a high incidence of that disease and the disease incidence in that group subsequently increases to match the incidence in the second location,what does this suggest about the disease etiology?

This suggests that the disease etiology is mostly environmental, as the increase in incidence corresponds with the movement to a new location. If it were mostly genetic, the incidence would not be expected to increase simply by moving to a new location. Additionally, if it were caused by factors such as food, this should not be affected by migration to a new location. However, it is possible that there is an interaction between genetic and environmental factors contributing to the higher incidence. Further research may be needed to fully understand the relationship between location, genetics, and disease incidence.
