The adage that the best is the enemy of the good, illustrated tragically in the strategy inadequate screening of the Covid-19 in the United States, argue that researchers who advocate the adoption of rapid tests in a dollar, not very precise but repeatable multiple times per week by the whole population.
Michael Mina, a professor of epidemiology at Harvard, has been fighting for weeks for what he called the tests of poor quality, " null ", or more colloquially as "shitty" (" crappy "). The idea is to bypass the current model of the molecular tests of high-precision (PCR tests), which are still too rare in a large part of the United States, for which people are often queuing for hours and waiting days, even weeks, for results.
