Accurate and rapid testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is crucial for controlling its spread. This study explains how to best use molecular and antigen tests in surveillance programs to prevent viral dissemination.
Area of Science:
- Virology
- Epidemiology
- Public Health
Background:
- The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic spread globally with unprecedented speed.
- Effective containment strategies like test-trace-isolate (TETRIS) are vital for controlling viral transmission.
Purpose of the Study:
- To provide guidance on interpreting and combining molecular and antigen-based detection methods for SARS-CoV-2.
- To outline optimal strategies for utilizing these tests within surveillance programs to prevent viral dissemination.
Main Methods:
- Discussion of the interpretation and combination of molecular and antigen detection methods for SARS-CoV-2.
- Algorithmic design for test application based on epidemiological contexts.
Main Results:
- Highlights the importance of accurate and rapid SARS-CoV-2 testing for effective pandemic response.
- Demonstrates how strategic application of testing algorithms can aid in controlling viral spread.
Conclusions:
- The judicious use and combination of molecular and antigen tests are essential for SARS-CoV-2 surveillance.
