May 2021 Update: SARS-CoV-2 Variants
The World Health Organization (WHO) has defined a SARS-CoV-2 isolate as a variant of interest (VOI) if it is phenotypically changed compared to a reference isolate of has a genome with mutations that lead to amino acid changes associated with established or suspected phenotypic implications; AND has been identified to cause community transmission/multiple COVID-19 cases/clusters, or has been detected in multiple countries.
A VOI is further classified as a variant of concern (VOC) if, through a comparative assessment, it has been demonstrated to be associated with:
- Increase in transmissibility of detrimental change in COVID-19 epidemiology;
- Increase in virulence or change in clinical disease presentation; or
- Decrease in effectiveness of public health and social measures or available diagnostics, vaccines, therapeutics.
Selected WHO-designated SARS-CoV-2 VOCs and selected VOIs, as of 1 June 2021.

Detection of key SARS-CoV-2 variants by Fortitude RT-PCR test kits
The MiRXES R&D team is constantly tracking the World Health Organization’s designation of new VOCs and VOIs and has performed in silico analyses to determine the sequence homology between the MiRXES Fortitude SARS-CoV2 RT-PCR primers and all SARS-CoV-2 sequences, including those of specific variants.
This table shows the percentage of aligned sequences in the GISAID database that have 100% homology to the primer (probe) sequence of the MiRXES Fortitude series RT-PCR test kits, as of 10 May 2021:
Overall, >99% of aligned sequences have 100% homology to either the ORF or N gene target sequence of MiRXES Fortitude RT-PCR test kits.
Sequence homology with | Fortitude 2.1 | Fortitude 3.0 | Fortitude Syndromic Panel |
|---|---|---|---|
All SARS-CoV-2 ORF target sequences | 99.63 | 99.6 | 97.9 |
All SARS-CoV-2 N gene target sequences | – | 93.5 | 98.7 |
B.1.1.7 lineage (UK) | 99.19 | 100 | 99.99 |
B.1.351 lineage (South Africa) | 100 | 100 | 100 |
