Corona Detective: a simple, scalable, and robust SARS-CoV-2 detection method based on reverse transcription...

Area of Science:

• Molecular diagnostics
• Infectious disease surveillance

Background:

• Large-scale surveillance is crucial for controlling the COVID-19 pandemic.
• Existing diagnostic methods may face limitations in accessibility and cost.

Purpose of the Study:

• To introduce Corona Detective, a novel molecular diagnostic test for SARS-CoV-2.
• To provide a sensitive, rapid, and low-cost solution for widespread surveillance.

Main Methods:

• Utilizes loop-mediated isothermal amplification (LAMP) for sensitive detection.
• Employs freeze-dried reagents for easy shipping and storage without cold-chain dependence.
• Features a sequence-specific quenched-fluorescence readout for accurate results and multiplexing capabilities with internal controls.

Main Results:

• Demonstrates a sensitive and rapid method for detecting the SARS-CoV-2 nucleocapsid gene.
• Ensures specificity through parallel positive and negative control reactions.
• Offers a user-friendly protocol and bioinformatics pipeline adaptable for viral variants.

Conclusions:

• Corona Detective offers a scalable, cost-effective solution for frequent population screening.
• The test's accessibility and ease of use support integration with vaccination campaigns for pandemic control.
• Open sharing of methods facilitates local production and diverse application formats.
