Explore, research, and present emerging and re-emerging infectious diseases, including factors in disease emergence, animal reservoirs, and the principles that govern the detection, mitigation and control of pandemic disease. Study a detailed analysis of host-pathogen interactions, illuminating how viral and bacterial pathogens defeat the host's immune defenses and cause disease. Examine representative emerging and re-emerging pathogens, case-based outbreak investigations, and individual case studies. Public Health 337 (Topic: Emerg/Re-emerg Infect Diseases) and 367 may not both be counted. Three lecture hours a week for one semester.
