About 78% of people who have been hospitalized, needed a ventilator or died from Covid-19 have been overweight or obese, the CDC said in a new study Monday. Just over 42% of the U.S. population was considered obese in 2018, according to the agency’s most recent statistics. … “As clinicians develop care plans for COVID-19 patients, they should consider the risk for severe outcomes in patients with higher BMIs, especially for those with severe obesity,” the CDC wrote.
