Highly Divergent SARS-CoV-2 Alpha Variant in Chronically Infected Immunocompromised Person
Emerging Infectious Diseases
|August 4, 2022
Summary
A highly divergent SARS-CoV-2 Alpha variant was found in an immunocompromised patient in the Netherlands. This persistent infection revealed new immune escape mutations in the spike protein.
Area of Science:
- Virology
- Immunology
- Genomics
Background:
- The SARS-CoV-2 Alpha variant previously circulated in the Netherlands.
- Immunocompromised individuals can experience prolonged viral infections.
Observation:
- A highly divergent SARS-CoV-2 Alpha variant was detected in an immunocompromised patient.
- The patient remained infected for 42 weeks despite multiple treatments.
Findings:
- The persistent infection involved a unique Alpha variant lineage.
- Several potential immune escape mutations were identified in the spike protein.
Implications:
- This case highlights the potential for prolonged SARS-CoV-2 infections in immunocompromised hosts.
- The identified mutations may inform understanding of viral evolution and immune evasion strategies.
- Further research is needed to understand the clinical and epidemiological significance of divergent variants in immunocompromised populations.

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

15.7K
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,...

23.7K
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.
