Mexican mogul Carlos Slim has been hospitalized with the coronavirus, his son announced Monday. Carlos Slim Domit said the 80-year-old billionaire began experiencing minor symptoms about a week ago, and he has been responding well to treatment. “He’s had a very favorable evolution to Covid over a week after what have been mild symptoms,” Slim Domit tweeted. The revelation comes a day after Mexico President Andres Manuel López Obrador revealed he has contracted COVID-19 and is isolating. “The symptoms are mild but I am already under medical treatment,” he wrote in a Twitter announcement. López Obrador has faced criticism for how he’s dealt with the outbreak in Mexico, where almost 150,000 people have died from the virus.
