Nevada’s COVID-19 response panel heard Thursday that the state is tallying more cases of coronavirus per capita than neighboring California and Arizona. State health officials reported separately a record 50 new deaths and 2,193 new COVID-19 cases, and a test positivity rate of 22.1% during the last two weeks. “Our test positivity rate is extremely high in Nevada right now,” according to Kyra Morgan, chief state biostatistician, who addressed the COVID-19 Mitigation and Management Task Force. She called the figure “obviously very alarming” and nearly the highest in the U.S.
