One-house one-person testing: Strategical plan to limit COVID-19 spread in stage three in the developing world

A strategy was proposed after the advent of a virus-specific molecular polymerase chain reaction (PCR) test called “mass screening” that involved testing nasal and throat swabs from the random population to assess viral spread and to isolate those infected from the healthy population.2 The strategy gained widespread approval in developed countries, and huge random populations were screened. [...]COVID-19 outbreaks across the globe have continued to occur, with less PCR testing of the population because of overburdened healthcare system and economic limitations under strict lockdowns. [...]if 1 person from the slum gets tested, there is a high probability that the test results reflect the status of those nearby.
