(CNN) Nurse Katie Sefton never thought Covid-19 could get this bad -- and certainly not this late in the pandemic. "I was really hoping that we'd (all) get vaccinated and things would be back to normal," said Sefton, an assistant manager at Sparrow Hospital in Lansing, Michigan. But this week Michigan had more patients hospitalized for Covid-19 than ever before. Covid-19 hospitalizations jumped 88% in the past month, according to the Michigan Health & Hospital Association.
