The actual numbers are believed to be much higher due to testing shortages, many unreported cases and suspicions that some governments are hiding the scope of their nations’ outbreaks.Since the first cases were detected in China in December, the United States has become the worst-affected country, with more than 2.7 million diagnosed cases and at least 128,740 deaths.Here’s how the news is developing Friday.

I know our entire campus community sends our deepest condolences to his family and friends as they grieve this unthinkable loss. It is a poignant reminder that no one among us is immune to the worst consequences of this virus.”Garcia was living off campus when he began to feel ill, according to the university statement.

Also, younger people, who get better much easier and faster!”However, Adm. Brett Giroir, the man Trump appointed to oversee testing, testified at a House hearing Thursday that “this is a real increase in cases” and not just attributable to increased testing.“There is no question that the more testing you get, the more you will uncover,” Giroir said Thursday. “But we do believe this is a real increase in cases because of the percent positives are going up. So, this is real increases in cases.”Giroir said the U.S. is not flattening the curve right now.“The curve is still going up,” he testified.Trump’s positively also comes the same day the Centers for Disease Control and Prevention updated its coronavirus death toll projections for July.
