Viral Recombination00:57

Viral Recombination

23.4K
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.

Viral Mutations00:36

Viral Mutations

32.3K
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...

Viral Structure

62.1K
Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.

Infection

7.9K
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...

Area of Science:

  • Virology
  • Epidemiology
  • Public Health

Background:

  • Rhinoviruses (RV) are common human respiratory viruses with significant antigenic diversity.
  • The dynamics of RV infections across different social structures are not well understood.

Purpose of the Study:

  • To analyze RV diversity and dynamics across distinct social structures in Kenya.
  • To investigate the relationship between population size and RV diversity.

Main Methods:

  • Analysis of VP4/2 sequences from four social structures: households, a primary school, Kilifi Health and Demographics Surveillance System (HDSS) outpatient clinics, and countrywide hospital admissions/outpatients.
  • Quantification of RV types within each social structure.

Main Results:

  • RV diversity was highest countrywide (114 types), followed by Kilifi HDSS (78 types), school (47 types), and households (40 types).
  • Over 90% of all known RV types were identified across these structures.
  • RV diversity showed a direct correlation with the size of the observed population.
  • Specific RV variants were observed to drive infection waves.

Conclusions:

  • Social structures play a critical role in shaping RV dynamics.
  • Population size is a key determinant of RV diversity.
  • Findings can inform enhanced public health strategies for managing RV infections.
  • Future research should consider whole-genome analysis for finer evolutionary insights.
