Transmission-based Precautions I: Contact, Enteric, and Droplets01:17

Transmission-based Precautions I: Contact, Enteric, and Droplets

4.2K
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Transmission-based Precautions II: Airborne and Protective Environment

1.6K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Infection01:20

Infection

9.4K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Contact-dependent Signaling01:19

Contact-dependent Signaling

45.4K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.
Gap Junctions
In animal cells, gap junctions are formed...

Area of Science:

  • Medical technology
  • Public health surveillance
  • Remote sensing applications

Background:

  • The COVID-19 pandemic necessitates rapid and accurate diagnostic tools.
  • Current methods like manual temperature screening have limitations.
  • Remote detection of symptoms is desirable for widespread screening.

Purpose of the Study:

  • To review and synthesize clinical literature on noncontact COVID-19 diagnosis.
  • To evaluate remote sensing technologies for detecting key symptoms.
  • To identify cost-effective and practical solutions for pandemic screening.

Main Methods:

  • Systematic review of clinical literature up to May 2020.
  • Analysis of noncontact vital sign monitoring technologies.
  • Evaluation of camera-based sensing methods (visible and thermal spectrum).

Main Results:

  • Common COVID-19 symptoms include fever, cough, fatigue, and visible infections.
  • Noncontact vital sign monitoring methods show potential but vary in performance.
  • Visible and thermal spectrum cameras offer the most promising noncontact detection capabilities.

Conclusions:

  • Thermal cameras excel at detecting temperature, a key fever indicator.
  • Visible spectrum cameras offer advantages in cost, availability, and adaptability.
  • Camera-based remote sensing is a viable strategy for noncontact COVID-19 symptom detection, considering cost and availability.
