Highly doubt that. The CDC would have been required to NOT screw up the test kits. All that would have happened is a delayed version of what's already happening. Community spread started in late January and the first confirmed COVID-19 death occurred in early February in Santa Clara County, although this wasn't known at the time. Taiwan backed up their mandatory quarantines with aggressive testing, but that requires that you can actually test and trace contacts. The US was not setup to do this because it didn't get hit hard enough by SARS and MERS and failed to learn the lesson by watching other countries fail. South Korea (hit by MERS in 2015) failed to learn the lesson by watching Hong Kong, Taiwan, and Singapore get hit hard by SARS, and those 3 failed to learn the lesson by reading papers by epidemiologists. It seems to be a common pattern in the world that a society needs to actually get screwed by an outbreak in order to create a plan to deal with one.
