This concentration will prepare students to collaborate on interdisciplinary teams that are currently needed to design , perform , and evaluate increasingly complex epidemiologic studies . This information will assist veterinarians to maintain awareness concerning the epidemiologic characteristics and the clinical signs of this new disease . The goals of hepatitis A surveillance at the national , state , and local levels include a ) monitoring disease incidence by identifying acute , symptomatic infections in all age groups ; b ) determining the epidemiologic characteristics of infected persons , including the source of infection ; c ) identifying contacts of case-patients who might require postexposure prophylaxis ; d ) detecting outbreaks ; e ) determining the effectiveness of hepatitis A vaccination ; and f ) determining missed opportunities for vaccination . Data access was requested only to confirm epidemiologic results that were claimed to support significant regulatory action . Although other tumors ( 12 skin cancers , 24 solid tumors of diverse types , and 1 multiple myeloma ) were also reported in this survey , epidemiologic analyses did not support a relationship to cyclosporine other than for malignant lymphomas . Recent publications from the epidemiologic and general medical literature will be used to illustrate the application of the concepts to specific epidemiologic issues . Different species have different syndromes ; the epidemiologic characteristics point out risk factors , which should increase or decrease the suspicion of listeriosis . As the epidemiologic characteristics of the pandemic virus are more clearly defined , CDC will provide updated infection control guidance , as needed . A representative surveillance system will better characterize the epidemiologic characteristics of a health event in a defined population .
