Variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce.

Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error).

Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.

Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster (bottleneck effect) or when a small group splits off from the main population to found a colony (founder effect).

In US hospitals, there are four common routes of transmission of infectious diseases. What are they?
liq [111]

Transmission is the stage in which the infectious agent gains a host and infects it. There are three main modes of transmission:

A. The transmission by contact:

Human-to-human transmission

Auto-infection (Some infections are endogenous, that is, they are caused by microorganisms that are part of normal flora but can become opportunistic pathogens.)

Indirect Contact Transmission (Indirect Contact Transmission refers to the propagation of a pathogen from a reservoir to a host through an object)

Droplet transmission (when a person coughs)

B. Transmission by a vehicle

Waterborne transmission

Foodborne transmission

Air transmission

C. Transmission by an animal vector

Mechanical transmission (In this type of transmission, insect vectors propagate infections passively.)

Biological transmission (This mode of transmission of vector-borne infections is much more complex, since the vector plays an active role in it.Normally, passage through the vector represents an essential step in the development of the pathogenic microorganism.)
