Define the terms: Contamination, Colonization, Infection, Inapparent/sub-clinical infection, Infectious disease/clinical infection, Probability of manifestation, Endogenous infection, Exogenous infect

Here are the explanations for the terms provided: Contamination*: This refers to the mere presence of microorganisms on objects, in the environment, or in samples, without necessarily causing infection or disease. Colonization*: This is the presence of microorganisms on skin or mucous membranes without penetrating into tissues. It can involve normal flora or, occasionally, pathogenic microorganisms that are not yet causing disease. Infection*: This is the invasion of a host organism by microorganisms, leading to their proliferation and a host reaction. Inapparent/sub-clinical infection*: This is an infection that occurs without any observable clinical symptoms. Infectious disease/clinical infection*: This is an infection that results in the outbreak of clinical symptoms, making the disease apparent. Probability of manifestation*: This is the frequency (expressed as a percentage) with which an infection will lead to clinical symptoms in an exposed individual. Endogenous infection*: This type of infection arises from microorganisms that are already part of the host's normal colonizing flora. Exogenous infection*: This is an infection that arises from the invasion of a host by microorganisms from external sources. Nosocomial infection*: This is an infection acquired during a hospital stay, such as a urinary tract infection, respiratory infection, wound infection, or sepsis. Local infection*: This is an infection that remains restricted to the initial portal of entry and the surrounding area. Generalized infection*: This involves the spread of an invading pathogen through the lymphatic system (lymphogenous) and/or bloodstream (hematogenous) from the portal of entry. It often involves infection of organs to which the pathogen has a specific affinity (organotropism) and progresses through incubation, generalization, and organ manifestation stages. Sepsis*: This is a systemic disease caused by microorganisms and/or their toxic products. It often involves pathogens or their toxins entering the bloodstream from a localized infection, either continuously or intermittently. Transitory bacteremia/viremia/parasitemia*: This describes the brief presence of bacteria (bacteremia), viruses (viremia), or parasites (parasitemia) in the bloodstream, typically occurring during the course of a first infection. Superinfection*: This is the occurrence of a second infection during the course of an existing first infection.
