[Mass testing for Covid-19 : what can we learn from real-world implementation ?]

Area of Science:

• Epidemiology
• Public Health Policy

Background:

• Modeling studies suggest mass testing for SARS-CoV-2 can be effective.
• Real-world implementation data is limited for evaluating mass testing's pandemic control impact.

Purpose of the Study:

• To evaluate the feasibility and effectiveness of mass testing strategies for SARS-CoV-2.
• To identify optimal approaches for utilizing testing interventions in pandemic control.

Main Methods:

• Review of existing modeling studies on mass testing.
• Analysis of real-world implementation challenges and outcomes.
• Assessment of rapid test utility for targeted screening.

Main Results:

• Mass testing requires sustained high participation and frequent testing alongside public health measures.
• Screening is more effective for targeted populations and high-risk events.
• Rapid tests offer a cost-effective solution for these targeted interventions.

Conclusions:

• Widespread, frequent mass testing for SARS-CoV-2 faces significant implementation hurdles.
• Targeted screening using rapid diagnostic tests is a more pragmatic approach for specific settings.
• Strategic use of rapid tests can aid in controlling SARS-CoV-2 transmission in defined high-risk environments.
