Summary
Influenza A virus (IAV) poses a significant global health threat, causing millions of infections and hundreds of thousands of deaths annually. This review details IAV
Area of Science:
- Virology
- Public Health
- Immunology
Background:
- Influenza A virus (IAV) is a major global health concern, causing annual epidemics and occasional pandemics.
- High mutation rates of hemagglutinin (HA) and neuraminidase (NA) proteins lead to novel strains, necessitating continuous vaccine and drug updates.
- IAV infections disproportionately affect the elderly, infants, and individuals with respiratory conditions.
Purpose of the Study:
- To provide a comprehensive review of influenza virus.
- To elucidate the genomic structure, evolution, pathogenicity, and clinical presentation of influenza virus.
- To aid in distinguishing influenza from other respiratory viruses and guide the development of new antivirals and vaccines.
Main Methods:
- Literature review and analysis of existing data on influenza virus.
- Examination of genomic, evolutionary, and pathogenic factors of IAV.
- Comparison of clinical presentations of influenza and other respiratory viruses.
Main Results:
- Influenza virus exhibits rapid evolution through antigenic drift and shift, driven by HA and NA protein mutations.
- Clinical diagnosis can be challenging due to symptom overlap with other respiratory viruses.
- Understanding IAV's characteristics is crucial for effective public health strategies.
Conclusions:
- A detailed understanding of influenza virus biology is essential for developing effective countermeasures.
- This review provides insights to differentiate influenza from other respiratory illnesses.
- Further research can accelerate the development of novel antiviral therapies and a universal influenza vaccine.

00:36Viral Mutations
32.1K
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...

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.

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

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,...
