Epidemiology is the study of health and disease conditions in defined populations of humans and animals. Epidemiology is essential for understanding how diseases emerge and spread, and for the development of effective control methods. The University of Liverpool's Institute of Infection and Global Health was established to bring together leading medical, veterinary and basic science researchers from across the Faculty of Health and Life Sciences. <br><br>In IGH we study the epidemiology of a range of infectious and non-infectious diseases of people and animals, including zoonotic diseases.<br><br>Epidemiological research in humans includes clinical and molecular epidemiological studies of a range of gastrointestinal, respiratory, vector-borne and sexually-transmitted infections of adults and children in the UK, Europe, Africa and Asia.<br><br>Epidemiological research in animals takes place predominantly at the Leahurst campus, where multidisciplinary staff, including clinically-qualified veterinary and medical researchers, statisticians, mathematicians and basic scientists, work together to address a range of issues. These include the epidemiology of zoonotic pathogens, the spread of antimicrobial resistance, understanding human behaviour as a driver of disease transmission, disease prevention and improving health and welfare in farmed and companion animals, and the influence of the environment and climate on the transmission of disease.
