In the latter part of the twentieth century, scientists became increasingly concerned about the threat of infectious diseases. Which of the following is not a reason why the incidence of infectious diseases has risen?

A) Advances in medicine

B) Mobile populations

C) Emerging microbes/diseases

D) Microbial adaptations

E) Ineffective diagnoses of diseases

Ineffective diagnoses of disease is not a reason for increasing infectious disease.

Explanation:

In twentieth century, as the number of disease are increased, scientists are more concern of producing the antibiotics for preventing the transmission. This in turn leads to change in the genetic material of the pathogen against the antibiotics.

Mobile population causes the significant proportion of chronic disease that spreads globally and is important reason for spreading of infectious diseases.

Emerging microbes are those microbes that are recently appear in the population and is rapidly increasing and is life threatening in future.

When a disease creating pathogen or microbe adapts different environmental conditions in such a way that they are less effected by any factors present in the environment and thus the population of these microbes increases rapidly and in turn creates disease.
