Insights

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), the virus causing COVID-19, spreads through presymptomatic and asymptomatic individuals. This review examines all transmission routes and prevention strategies to curb its spread.

Area of Science:

  • Virology
  • Infectious Diseases
  • Public Health

Background:

  • Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) causes coronavirus disease-2019 (COVID-19), a global health crisis.
  • The virus's efficient spread is partly due to transmission from presymptomatic and asymptomatic individuals.
  • Standard precautions include droplet and contact measures, with airborne and eye protection for healthcare workers.

Purpose of the Study:

  • To conduct an evidence-based review of all potential transmission routes of SARS-CoV2.
  • To discuss comprehensive preventive measures against the spread of COVID-19.
  • To highlight the need for increased awareness among healthcare professionals, governments, and the public.

Main Methods:

  • Literature review of existing studies on SARS-CoV2 transmission.
  • Analysis of viral presence in various body fluids.
  • Synthesis of data on transmission dynamics and prevention strategies.

Main Results:

  • SARS-CoV2 transmission occurs efficiently, including from individuals without symptoms.
  • Viral particles have been detected in diverse bodily fluids such as feces, saliva, semen, and tears.
  • This suggests potential for transmission through routes beyond respiratory droplets.

Conclusions:

  • Universal precautions are essential, but awareness of all transmission routes is critical.
  • Enhanced education on potential transmission pathways is urgently needed for all stakeholders.
  • Strict adherence to comprehensive preventive measures is vital to control the COVID-19 pandemic.

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

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...

Infection01:20

Infection

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...

Transmission-based Precautions II: Airborne and Protective Environment

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...

Standard Precaution

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Conjugated Proteins02:50

Conjugated Proteins

Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with non-protein moieties.
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
