Infectious diseases research focuses on studying the causes, transmission, prevention, and treatment of diseases caused by pathogens such as bacteria, viruses, fungi, and parasites. Researchers in this area work to understand how these pathogens infect and spread within human populations, as well as how the immune system responds to these infections. The ultimate goal of infectious diseases research is to develop interventions, such as vaccines and antimicrobial therapies, to control and prevent the spread of these diseases. This field is important for public health and has broader implications for global health security.
