Pathogen transmission. In medicine, public health, and biology, transmission is the passing of a pathogen causing communicable disease from an infected host individual or group to a particular individual or group, regardless of whether the other individual was previously infected. [1] The term strictly refers to the transmission of ...
The Reed–Frost model is a mathematical model of epidemics put forth in the 1920s by Lowell Reed and Wade Hampton Frost, of Johns Hopkins University. [1] [2] While originally presented in a talk by Frost in 1928 and used in courses at Hopkins for two decades, the mathematical formulation was not published until the 1950s, when it was also made into a TV episode.
Sepsis is a potentially life-threatening condition that arises when the body's response to infection causes injury to its own tissues and organs. [4][7] This initial stage of sepsis is followed by suppression of the immune system. [8] Common signs and symptoms include fever, increased heart rate, increased breathing rate, and confusion. [1]
Tuberculosis (TB), also known colloquially as the " white death ", or historically as consumption, [8] is an infectious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. [1] Tuberculosis generally affects the lungs, but it can also affect other parts of the body. [1] Most infections show no symptoms, in which case it is known ...
Compartmental models are a very general modelling technique. They are often applied to the mathematical modelling of infectious diseases. The population is assigned to compartments with labels – for example, S, I, or R, (S usceptible, I nfectious, or R ecovered). People may progress between compartments. The order of the labels usually shows ...
Chain of infection; the chain of events that lead to infection. There is a general chain of events that applies to infections, sometimes called the chain of infection [15] or transmission chain. The chain of events involves several steps – which include the infectious agent, reservoir, entering a susceptible host, exit and transmission to new ...
The serial interval in the epidemiology of communicable (infectious) diseases is the time between successive cases in a chain of transmission. [1] The serial interval is generally estimated from the interval between clinical onsets (if observable), in which case it is the 'clinical onset serial interval'. It could in principle be estimated by ...
Infectious mononucleosis (IM, mono), also known as glandular fever, is an infection usually caused by the Epstein–Barr virus (EBV). [2][3] Most people are infected by the virus as children, when the disease produces few or no symptoms. [2] In young adults, the disease often results in fever, sore throat, enlarged lymph nodes in the neck, and ...
