Mexico shuns Covid-19 testing even though Half of All Covid Tests Are Positive.

The sky-high results are easy to explain -- though not so easy to fix. The Latin American nation has stubbornly shunned wide-scale testing and instead runs exams only on the sickest of patients. Deputy Health Minister Hugo Lopez Gatell in late May said anything more would be "a waste of time, effort and resources."

Throughout the pandemic, Mexico and parts of Latin America have reported positivity rates that dwarf anything seen from China to the U.S., including new trouble spots like Arizona and Texas. With half of all tests coming back positive, Mexico ties only Bolivia for title of the world's highest rate. In Argentina and Chile, almost 3 out of every 10 exams lead to a Covid-19 diagnosis. And in Brazil, where 1.4 million people have been infected, no one knows for sure because the government doesn't release that data.
