* The number of tests represents the total number, including tests at the time of discharge. It is determined by summing up the “number of PCR tests performed (counted foreach prefecture by public health institutes/public health centers, private inspection laboratories, and universities/medical facilities)” and the “number of persons who
underwent an antigen test (sampling) (counted for each prefecture by public health institutes/public health centers and universities/medical facilities).”* The “number of test-positive persons/number of tests” is calculated mechanically with the “number of tests (including tests at discharge)” as the denominator and the“number of new positive cases” as the numerator. The calculation result may exceed 100% due to the influence of delays in reporting the number of tests, so attention
should be paid to interpreting the results including those of other prefectures.
