We agree entirely that the proposed pool testing mathematical strategy [Reference Chow and Chow1] is needed [Reference Zavascki2] in low-income countries, assisting the government in operating the public health system. The resources bottleneck can be solved via applying optimised testing policies in low-resource setting.

Further, if the mathematical strategy is well supported by disaster management personnel, quick, reliable and cheap detection testing schemes on coronavirus disease 2019 (COVID-19) with smaller number of tests can be worked out.

Another update on recent mandatory testing [Reference Cheung, Cheung and Lam3] in several suburbs with confirmed infection cases, the pooling testing strategy will be useful in handling thousands of tests quickly for picking up asymptomatic patients at a certain time. Although residents having negative results are not yet safe, and they are asked to do the test again a few days later.
