Other symptoms can include: hallucinations and delusions; increased agitation and confusion; depression and other mood disorders; personality changes, such as irritability and a reduced threshold for frustration; and an inability to focus or concentrate.
One explanation could be the differences in climate (environmental factors). The climate in northern Mexico could support the reproduction of the mosquito species, which is a vector of the dengue virus. Other environmental conditions that influence its endemicity could include living conditions and sanitation. The other possiblity could be that the people in the US have developed immunity for the disease, therefore, are unaffected even when infected by the virus.

Answer:
The correct answer is "the bottleneck effect".
Explanation:
The bottleneck effect, also known as a population bottleneck or genetic bottleneck, is defined as sharp reduction of a species population that occurs either by environmental effects or as a consequence of human activities. The dramatical crash the that population of American bison had due to hunting and other problems is an example of a species suffering the bottleneck effect.
I think this is an example of competitive exclusion principle. Competitive exclusion principle is a proposition that two species competing for the same limiting resource can not coexist at constant population values.For Example the Red squirrel is native to Britain but its population has declined due to competitive exclusion, disease and the disappearance of hazel coppices and mature confer forests i law land Britain.
