This module focuses on infectious diseases of public health concern in Singapore and internationally. The course will cover concepts in the prevention, surveillance and control of infectious diseases, with a focus on vector-borne diseases (in particular dengue and malaria), foodborne diseases, HIV/AIDS and sexually transmitted diseases, tuberculosis, acute respiratory illnesses, and nosocomial infections. In addition, students will be exposed to concepts in the evaluation of vaccines and vaccination programmes, and will obtain hands-on experience in outbreak investigation through a simulated outbreak exercise. Students will learn to critically appraise and discuss the application of current control strategies. This module is highly relevant for students who intend to work in infectious disease control in local and international governmental and non-governmental organisations, or who wish to pursue academic research on infectious diseases from a public health perspective.
