Veterinary Epidemiology and Zoonosis

EXPERIMENTAL EPIDEMIOLOGY

• The experimental epidemiologist will observe and analyze data by conducting experiments.
• The epidemiologist will allot animals into different groups and can alter the factors associated with the groups (epidemiologist is having control over the groups).
• Most of the research activities in Veterinary field deal with experimental observations compared to the descriptive observations made in natural cases in human medicine.
• Experimental or intervention studies are similar in approach to cohort studies excepting that the conditions in which study is carried out are under the direct control of the investigator.
• The aim of experimental studies is to provide scientific proof of etiological factors and provide a method of measuring the effectiveness and efficiency of health services for the prevention, control and treatment of disease.
• Experimental studies are of two types,
  • Randomized controlled trials
  • Non randomized trials
