Iproving the sensor to be better faster, or cheaper is a way we did quick classification of possibilities.  And thoughts to risk of application.

For Quick Coronavirus Testing, Israel Turns to Clever Algorithm

Israeli scientists have created a coronavirus testing procedure that they claim is faster and more efficient than any currently in use, testing samples in pools of up to 48 people simultaneously. The Pooling-Based Efficient SARS-CoV-2 Testing (P-Best) method requires only a single round of testing, based on an algorithm created by the Open University of Israel's Noam Shental. The P-Best algorithm optimizes pool design based on the expected prevalence of the virus, enabling all positive individuals in a batch to be localized, provided the total number of positives does not sharply surpass the expected number. Although the technique is less effective the higher a community's positivity rate is, it offers dramatically greater efficiency when rates are lower. P-Best accurately screened 1,115 healthcare workers with just 144 tests.  ... "
