The US has significantly ramped up testing since its failure in the spring. On average, more than 640,000 tests were done in the country per day in the last week, according to the COVID Tracking Project. But a pandemic roadmap from Harvard experts suggested the US should be scaling up to 20 million tests per day by the end of July. Anthony Fauci, the US's top infectious-disease expert, told CNBC that ideally, the country would be "flooding the system with testing, so you really get a good handle about what is going on in the community." That, of course, is not happening. Instead, America's testing infrastructure is once again losing its grip as the larger-than-ever surge of new cases strains the system past its limits.
