Area of Science:

• Virology
• Genomics
• Biotechnology

Background:

• The genomic sequence of SARS-CoV-2 is known, sharing similarities with SARS-CoV (80%) and MERS-CoV (50%).
• The global rise in COVID-19 cases and fatalities has increased the demand for accurate diagnostic tools like RT-PCR kits.

Purpose of the Study:

• To develop a novel algorithm for identifying low mutation rate regions in the SARS-CoV-2 genome.
• To design primers targeting these stable regions for improved RT-PCR assay accuracy and long-term feasibility.

Main Methods:

• A new algorithm was developed to analyze the SARS-CoV-2 genome for regions with minimal mutation rates.
• Primers were designed based on the identified low-mutation regions.

Main Results:

• The study presents a novel algorithm for pinpointing stable genomic areas within SARS-CoV-2.
• Primers were successfully designed using this algorithm, targeting conserved regions of the virus.

Conclusions:

• The developed algorithm offers a method to enhance the accuracy and reliability of SARS-CoV-2 RT-PCR diagnostics.
