An infectious disease is a clinically evident disease resulting from the presence of pathogenic microbial agents, including pathogenic viruses, bacteria, fungi, parasites, and aberrant proteins known as prions. Infectious diseases are usually qualified as contagious due to their potential of transmission from one person or species to another. Transmission may occur through diverse pathways such as contaminated objects, airborne inhalation, sexual contact or through vector-borne spread.
