Resource Optimization through Group, Pooling, Tests, Testing in the Detection of Asymptomatic People with COVID-19

2021 Microbiology, Immunology and Pathology  
The current ongoing coronavirus disease 2019 (COVID-19 SARS2) pandemic with mainly severe acute respiratory syndrome, is a serious global public health problem. The detection and isolation of infected people with the virus is crucial. Hitherto, the real-time polymerase chain reaction (RT-PCR) test has proven to be most useful in viral detection when performed using nasal and oropharyngeal exudate samples. Due to the global and rapidly progressive nature of the pandemic, the tests have been

The Many millions of tests have been performed almost exclusively on an individual basis and are many millions of tests [1] . To date, the United Kingdom has performed the highest number of tests globally, with 486 billion tested inhabitants [2] . In the open population, the first positivity reported by South Korea, who had performed the greatest number of tests, the statistic of positives was 1.7% in the open population, and later in May 2020 they performed 10 million tests and only had 300 positives (positivity rate of 0.9% of positivity) between 1,553,5523.. In the United States of America, the positivity rate in the suspected sample population was 19.8% and 9.6% in the general population of 32,009,840 by July 25, 20204. Based on this percentage, the negativity rate in the general population is expected to be high. It is known that a person infected by COVID-19 (SARS-CoV-2) who is asymptomatic, has an approximate viral load of 6.76 x 106 viral copies in the first five days of infection [3][4] [5] [6] [7] [8] [9] . Subsequently, the
