A latent function of a behavior is not explicitly stated, recognized, or intended by the people involved. Thus, they are identified by observers. [5] In the example of rain ceremony, the latent function reinforces the group identity by providing a regular opportunity for the members of a group to meet and engage in a common activity. [4]
In epidemiology, particularly in the discussion of infectious disease dynamics (modeling), the latent period (also known as the latency period or the pre-infectious period) is the time interval between when an individual or host is infected by a pathogen and when that individual becomes infectious, i.e. capable of transmitting pathogens to ...
In a typical infectious disease, the incubation period signifies the period taken by the multiplying organism to reach a threshold necessary to produce symptoms in the host. While latent or latency period may be synonymous, a distinction is sometimes made whereby the latent period is defined as the time from infection to infectiousness. Which ...
Sociobiology is a field of biology that aims to explain social behavior in terms of evolution.It draws from disciplines including psychology, ethology, anthropology, evolution, zoology, archaeology, and population genetics.
An example of such a gene product is the latency associated transcripts (LAT) in herpes simplex virus, which interfere with apoptosis by downregulating a number of host factors, including major histocompatibility complex (MHC) and inhibiting the apoptotic pathway. [17] A certain type of latency could be ascribed to the endogenous retroviruses.
Latent effects are biological or developmental early life experiences that influence health later in life. Low birth weight, for instance, is a reliable predictor of incidence of cardiovascular disease and adult-onset diabetes in later life. Nutritional deprivation during childhood has lasting health effects as well.
Typhoid Mary, pictured above in a 1909 tabloid, was a famous case of a subclinical infection of Salmonella enterica serovar.. 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]
Although health research is often organized by disease categories or organ systems, theoretical development in social epidemiology is typically organized around factors that influence health (i.e., health determinants rather than health outcomes). Many social factors are thought to be relevant for a wide range of health domains.
