Summary
The origin and animal hosts of SARS-CoV-2 (the virus causing COVID-19) remain unclear, complicating prevention. Understanding the human-animal interface is crucial for effective control strategies.
Area of Science:
- Veterinary Medicine
- Epidemiology
- Zoonotic Diseases
Background:
- COVID-19, caused by SARS-CoV-2, emerged in 2019 with zoonotic origins, but the precise spillover source and intermediate hosts are unidentified.
- The emergence of new susceptible animal species raises concerns about viral replication and potential intra- and interspecies transmission, complicating public health efforts.
- Mapping disease patterns requires understanding the role of animals and their products in SARS-CoV-2 epidemiology.
Purpose of the Study:
- To review current knowledge on SARS-CoV-2 infection at the human-animal interface.
- To explore the genetic relatedness and origins of SARS-CoV-2 variants in animals.
- To assess the role of animals and their products in disease transmission and discuss contamination potential.
Main Methods:
- Literature review of recent updates on SARS-CoV-2 at the human-animal interface.
- Analysis of postulations regarding the genetic origins of animal-isolated SARS-CoV-2 variants.
- Examination of studies on animal roles in transmission, virus contamination, and environmental stability.
Main Results:
- The review synthesizes information on SARS-CoV-2 susceptibility in various animal species and its implications for disease spread.
- Evidence regarding the potential role of animal products in SARS-CoV-2 transmission is discussed.
- Current prevention and management strategies for SARS-CoV-2 are reviewed.
Conclusions:
- Further research into the epidemiology of SARS-CoV-2 at the human-animal interface is essential for effective prevention and control.
- One Health-based control measures are proposed as a valuable approach for managing future zoonotic disease threats.
- Identifying the source and understanding animal involvement are critical for mitigating the impact of SARS-CoV-2.

Viral Recombination
24.0K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Single Nucleotide Polymorphisms-SNPs
16.8K
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,...

Rous Sarcoma Virus (RSV) and Cancer
5.5K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

Conjugated Proteins
20.3K
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...
