Household representative sample strategy for COVID-19 large-scale population screening.

Area of Science:

• Epidemiology
• Infectious Disease Control
• Public Health

Background:

• The COVID-19 pandemic necessitates efficient testing for identification, isolation, and transmission control.
• Group testing has been applied to infectious diseases, including COVID-19, but faces challenges like sample dilution and resource strain.
• Large pool sizes in group testing can reduce detection sensitivity due to sample dilution.

Purpose of the Study:

• To propose an alternative group testing strategy for large-scale COVID-19 population testing.
• To reduce the number of samples collected and pooled, thereby conserving resources like test kits.
• To introduce a database system for continuous monitoring of population virus exposure.

Main Methods:

• A novel group testing strategy involving pooled samples from individuals across different households.
• Implementation of a database system for ongoing population surveillance.
• Testing of pooled samples to identify infections within the population.

Main Results:

• The proposed strategy aims to mitigate sample dilution issues associated with large pool sizes.
• Reduction in the total number of samples required for large-scale testing.
• Enhanced efficiency in resource utilization for COVID-19 testing.

Conclusions:

• The presented strategy offers an improved approach to group testing for COVID-19.
• This method can enhance the efficiency and sensitivity of large-scale population testing.
• Continuous monitoring via a database system supports better public health decision-making.
