[New viruses: myth, fantasy or reality?].
Revue Medicale Suisse
|June 10, 2014
Summary
Emerging viruses are frequently in headlines due to rapid evolution and global factors. Despite advanced detection, predicting viral outbreaks remains unreliable, a challenge for epidemiology.
Area of Science:
- Virology
- Epidemiology
- Public Health
Context:
- Increasing frequency of emerging viruses in human populations.
- Role of rapid viral evolution and adaptation.
- Influence of globalization (travel, trade) and climate change.
Purpose:
- To analyze the factors contributing to the perceived increase in emerging viral threats.
- To discuss the limitations of current surveillance and prediction models.
- To highlight the challenges in virological prediction for epidemiology.
Summary:
- Emerging viruses are prominent due to their rapid evolution and adaptation.
- Globalization and climate change facilitate viral spread and detection.
- Enhanced surveillance detects zoonotic spillover events more readily.
- Despite technological advancements, predicting viral epidemiology remains highly unreliable.
Impact:
- Highlights the complex interplay between viral characteristics and global changes.
- Underscores the need for realistic expectations regarding viral outbreak prediction.
- Informs public health strategies by acknowledging the inherent uncertainties in virology.

22.2K
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.

00:36Viral Mutations
32.9K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible...

12.0K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
