Clinical infectiology is the medical specialty focused on the diagnosis, treatment, and management of infectious diseases in humans. It encompasses the study of pathogens, their transmission, epidemiology, and host immune responses. Infectious disease specialists, microbiologists, and epidemiologists collaborate to diagnose infections, prescribe appropriate treatments (such as antibiotics or antivirals), and implement infection control measures to prevent outbreaks. Clinical infectiology addresses a wide range of infections, from common respiratory viruses to emerging pathogens, emphasizing evidence-based medicine and public health strategies. Research in this field aims to advance diagnostics, therapies, and vaccination strategies against infectious diseases, improving global health outcomes.
