The Ministry of Health says Saturday that another 455 cases of COVID-19 were added to the toll of the infection since March. But it says that 68 of them should have been included in earlier reports, meaning that the true number of cases confirmed over the last 24 hours is 387. True number or otherwise, the complex and often murky process of tracking the deadly virus continues to challenge those charged with the job. Just when and how these additional 68 cases got lost is not explained except as a mix-up between labs. A rolling five-day average of new cases stands at 374. Saturday’s report notes an impressive 23,105 tests performed in the last 24-hour reporting period. Daily summaries since March
