Mexico reported an additional 2,437 coronavirus cases on Friday, the highest day-to-day increase for the country, according to a press conference by Mexico’s General Director of Epidemiology Jose Luis Alomia.

Friday marks the second day in a row Mexico has reported more than 2,400 confirmed cases, bringing the case count to 45,032 across the country.

Despite mounting cases, a three-phased plan to re-open Mexico’s economy beginning June 1 was announced this week.

No mass testing: Mexican health officials believe the outbreak will peak in this country no later than May 20, though some studies suggest it could arrive in late June, even as the country has one of the lowest testing rates in the world.

As of May 11, Mexico had only conducted 89 tests per 100,000 people, according to health ministry data. By contrast, the US tested at a rate nearly 32 times higher than that, according to the COVID Tracking Project.

But the lack of testing has prompted criticism that a dearth of confirmed data has left the government with, at best, an incomplete view of how bad the outbreak is just weeks before the country will start to re-open.
