16 Facts About Community 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.

Indirect Community transmission could involve zoonoses or, more typically, larger pathogens like macroparasites with more complex life cycles.

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.

Local Community transmission means that the source of the infection has been identified within the reporting location.

Route of Community transmission is important to epidemiologists because patterns of contact vary between different populations and different groups of populations depending on socio-economic, cultural and other features.

Common form of Community transmission is by way of respiratory droplets, generated by coughing, sneezing, or talking.

Organisms spread by droplet Community transmission include respiratory viruses such as influenza virus, parainfluenza virus, adenoviruses, rhinovirus, respiratory syncytial virus, human metapneumovirus, Bordetella pertussis, pneumococci, streptococcus pyogenes, diphtheria, rubella, and coronaviruses.

Additionally, while fecal–oral Community transmission is primarily considered an indirect contact route, direct contact can result in Community transmission through feces.

Fecal–oral Community transmission is primarily considered as an indirect contact route through contaminated food or water.

Main causes of fecal–oral disease Community transmission include lack of adequate sanitation and poor hygiene practices - which can take various forms.

Fecal oral Community transmission can be via foodstuffs or water that has become contaminated.

Fecal-oral route of Community transmission can be a public health risk for people in developing countries who live in urban slums without access to adequate sanitation.

Relationship between virulence and Community transmission is complex and has important consequences for the long term evolution of a pathogen.

Mode of Community transmission is an important aspect of the biology of beneficial microbial symbionts, such as coral-associated dinoflagellates or human microbiota.

Mixed-mode Community transmission can allow symbionts to have the “best of both worlds” – they can vertically infect host offspring when host density is low, and horizontally infect diverse additional hosts when a number of additional hosts are available.

Mixed-mode Community transmission make the outcome of the relationship more difficult to predict, because the evolutionary success of the symbiont is sometimes but not always tied to the success of the host.
