Recent advances in the nucleic acid-based diagnostic tool for coronavirus

Area of Science:

• Virology
• Molecular Biology
• Infectious Diseases

Background:

• A novel coronavirus, SARS-CoV-2, emerged causing the COVID-19 pandemic with pneumonia-like symptoms.
• This virus belongs to the same family as SARS and MERS, affecting the respiratory system.
• Current detection relies heavily on polymerase chain reaction (PCR) methods.

Purpose of the Study:

• To summarize existing nucleic acid-based diagnostic methods for coronavirus detection.
• To identify the limitations of current diagnostic approaches.
• To emphasize the need for improved, rapid, sensitive, and specific diagnostic tools for SARS-CoV-2.

Main Methods:

• Review of currently available nucleic acid-based diagnostic techniques for coronavirus.
• Analysis of the advantages and disadvantages of methods including PCR, microarray, real-time quantitative PCR, and CRISPR-Cas13.
• Discussion on the limitations hindering widespread and rapid diagnosis.

Main Results:

• Existing methods like PCR, while effective, present various limitations.
• Improved techniques such as real-time PCR and CRISPR-Cas13 offer advancements but still have drawbacks.
• A significant need exists for diagnostic tools that are faster, more sensitive, and can process more samples efficiently.

Conclusions:

• Nucleic acid-based detection is crucial for diagnosing SARS-CoV-2 infections.
• Current methods require enhancement to meet the demands for rapid and accurate large-scale testing.
• Development of superior diagnostic technologies is essential for effective pandemic control.
