____7. If the central epidemiologist is not satisfied with the field staff's ability to investigate a rumor, one or more epidemiologists should be sent to the field.

____8. The investigation of rumors requires specialized skills most epidemiologists do not have.

____9. Mistaken diagnosis of a communicable disease may be given because of lack of experience of the medical staff.

____10. In reporting epidemiologic information to higher authorities the epidemiologist should present the preferred solution in nontechnical terms, since the decision makers do not have the background knowledge to choose from a number of alternatives.
