transmission

Examples of transmission in the following topics:

• Chain of Transmission

  • The most important and frequent mode of transmission of nosocomial infections is by direct contact.
  • The most important and frequent mode of transmission of nosocomial infections is by direct contact.
  • Vector borne transmission occurs when vectors such as mosquitoes, flies, rats, and other vermin transmit microorganisms.
  • Contact transmission is divided into two subgroups: direct-contact transmission and indirect-contact transmission.
  • Differentiate between the various types of transmission: air-borne, common vehicle, vector borne, direct and indirect contact transmission

• Airborne Transmission of Disease

  • The airborne transmission that occurs utilizes small particles or droplet nucleithat contains these infectious agents or pathogens.
  • Many types of infections that can be a result of airborne transmission include: Anthrax, Chickenpox, Influenza, Measles, Smallpox, and Tuberculosis.
  • Airborne transmission of disease is common in unsanitary household conditions and overcrowded areas, and pathogens that are transmitted in this manner thrive in areas of poverty and poor hygienic conditions.

• Portals of Microbe Entry

  • airborne transmission (if the microorganism can remain in the air for long periods)
  • Infectious agents are generally specialized for a particular method of transmission.
  • In fecal-oral transmission, it is through the mouth.
  • In vector-borne transmission, it is at the bite or sting of the vector.
  • Recognize the various methods and types of microorganism transmission: vectors, hosts, horizontal, vertical transmissions

• Infectious Disease Transmission

  • Defining the means of transmission of a pathogen is important in understanding its biology and in addressing the disease it causes.
  • Transmission may occur through several different mechanisms.
  • A common method of transmission in under-developed countries is fecal-oral transmission.
  • Transmission of infectious diseases may also involve a vector.
  • Give examples of various modes of transmission, including direct and indirect transmission

• Portals of Exit

  • Transmission is the passing of a communicable disease from an infected host individual or group to a conspecific individual or group by one or more of the following means: droplet contact, direct physical contact, indirect physical contact, airborne transmission, and fecal-oral transmission.
  • Transmission can also be indirect, via another organism.
  • The second is vertical disease transmission – passing a disease causing agent vertically from parent to offspring, such as through perinatal transmission.
  • Direct fecal-oral transmission is rare for humans at least.
  • Some diseases transmissible by the sexual route include: HIV/AIDS and chlamydia.

• Reflection and Transmission

  • When the medium changes, a wave often experiences partial transmission and partial refection at the interface.
  • Transmission permits the passage of wave, with some or none of the incident wave being absorbed.
  • Reflection and transmission often occur at the same time .
  • When the string is driven by an external force, partial reflection and transmission occurs as in Figure 18426.
  • We can define the transmission (t) and reflection (r) coefficients as

• Synaptic Transmission

  • Synaptic transmission is a chemical event which is involved in the transmission of the impulse via release, diffusion, receptor binding of neurotransmitter molecules and unidirectional communication between neurons.
  • The chemical event is involved in the transmission of the impulse via release, diffusion, receptor binding of neurotransmitter molecules and unidirectional communication between neurons.

• Cultural Transmission

  • Cultural transmission is the way a group of people within a society or culture tend to learn and pass on new information.
  • Cultural transmission is the way a group of people or animals within a society or culture tend to learn and pass on new information.
  • Analyze the importance of cultural transmission, particularly in terms of learning styles

• Radio Waves

  • The lowest commonly encountered radio frequencies are produced by high-voltage AC power transmission lines at frequencies of 50 or 60 Hz.
  • These extremely long wavelength electromagnetic waves (about 6000 km) are one means of energy loss in long-distance power transmission.
  • FM radio waves are also used for commercial radio transmission, but in the frequency range of 88 to 108 MHz .
  • Electromagnetic waves also broadcast television transmission.
  • Note that these frequencies are those of free transmission with the user utilizing an old-fashioned roof antenna.

• Animals and Culture

  • This process, most agree, involves the social transmission of a novel behavior, both among peers and between generations.
  • The acquisition and sharing of behaviors correlates directly to the existence of memes, which are defined as "units of cultural transmission" by the evolutionary biologist Richard Dawkins.
  • Darwin was also the first to suggest what became known as 'social learning' in explaining the transmission of an adaptive behavior pattern throughout a population of honey bees.
