Infectious Disease Epidemiology Research
Infectious diseases (ID) remain key public health problems. In the developing world, diarrheal infections, respiratory infections, AIDS, malaria and tuberculosis are the principal causes of morbidity and mortality. Globally, pneumonia, meningitis, and nosocomial infections remain serious and costly health problems. Global travel and migration increase everyone’s susceptibility to epidemic and emerging diseases, from both natural (e.g., bird flu) and deliberate (terrorism) causes. The emergence and dissemination of drug resistant microorganisms represent an expanding threat. At the same time, our abilities to develop and deliver new drugs and vaccines to control these diseases have also increased. Infectious disease epidemiologists are needed to improve surveillance, identify newly emerging infections, understand transmission dynamics, and develop and evaluate prevention and control strategies.
The ID epidemiology program at UNC benefits from a close collaborative relationship with other units at UNC, such as:
- Understand the pathogenesis of infectious diseases including:
- Route of pathogen entry
- Host responses, including innate and acquired immunity
- Relationship between disease and virulence factors, immune avoidance mechanisms, and pathogen host interactions
- Host and microbial genetic factors
- Be familiar with the natural history of major infectious diseases;
- Understand the social, economic, behavioral, demographic and environmental determinants of infections, particularly emerging infections;
- Understand the causes for the enormous disproportion in infectious disease burden between resource poor and resource rich countries;
- Understand the special status in infectious disease prevention and control in marginalized populations such as prisoners, homeless, uneducated and persons of color;
- Be familiar with key surveillance systems and other sources of data relevant to the problem;
- Understand strategies for early detection and control of episodes of bioterrorism;
- Understand the principles and practices of outbreak investigation;
- Be familiar with the broad principles of infectious disease prevention including strategic use of prophylactic vaccines and vector control;
- Be familiar with the basic strategies for treatment of infectious diseases including use of antimicrobials;
- Understand the principles associated with infectious disease elimination;
- Be familiar with the broad principles of infectious disease modeling;
- Apply epidemiologic methods in the design, conduct and analysis of infectious disease epidemiologic studies;
- Communicate epidemiology concepts, methods and findings to community groups, state and local health departments, heath professionals and at-risk populations.
