  In 1998, of a global total of 54 million deaths, 16.7 million were due to circulatory diseases; 13.5 million were due to infectious diseases; and 7 million were due to cancer. The World Health Organization estimated that infectious diseases caused over 13 million deaths - almost a quarter of total deaths worldwide. Among the most common causes of mortality were the three diseases: pneumonia (3.5 million), diarrheal disease (2.2 million) and tuberculosis (1.5 million). Other important infectious causes of death were acquired immunodeficiency syndrome (2.3 million), malaria (1.1 million), and measles (1.0 million).

  Despite the extensive use of antimicrobial agents and vaccination programs, infectious diseases continue to be a major cause of morbidity and mortality worldwide. Widespread antimicrobial resistance, the emergence of new pathogens in addition to the resurgence of old ones, and the lack of effective new therapeutics exacerbate the problems.

  Our research involves a spectrum of basic and clinical investigations of infectious diseases which are focused on an understanding of host responses against infectious pathogens and development of immune-based interventions which, in turn, can be directly applied to human diseases. The ultimate goal of our laboratory is to promote the prevention and improve the treatment of infectious diseases, for the benefit of patients and the public.
