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 ...
A subclinical infection—sometimes called a preinfection or inapparent infection—is an infection by a pathogen that causes few or no signs or symptoms of infection in the host. [1] Subclinical infections can occur in both humans and animals. [ 2 ]
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
Antigen detection, polymerase chain reaction assay, virus isolation, and serology: Most infections are mild and require no therapy or only symptomatic treatment.

For example, the dead body of an individual who died of Ebola remains very infectious for up to a week. [ 4 ] A related concept is the shedding period , which is the time interval during which a host or patient excretes the pathogenic organism through saliva, urine, feces or other bodily fluids.
An Ohio county is experiencing a pediatric outbreak of pneumonia, including a number of cases of mycoplasma pneumonia, the illness that has driven recent outbreaks among children in Denmark and China.
Transmissibility is the probability of an infection, given a contact between an infected host and a noninfected host. [8] Community transmission means that the source of infection for the spread of an illness is unknown or a link in terms of contacts between patients and other people is missing. It refers to the difficulty in grasping the ...
