(CNN) - As new cases of coronavirus arise daily in the United States -- including several announced over the weekend and one death -- the US Centers for Disease Control and Prevention has failed to release crucial information physicians say could help save the lives of Americans diagnosed with the novel coronavirus.

Several US patients have recovered from coronavirus, but so far, the CDC has shared detailed clinical information about only one of those patients. That information includes what treatments the patients received and how they fared.

The CDC is the federal agency that communicates with physicians about how to handle outbreaks. Whether it's SARS, Ebola or last year's measles outbreak, the agency uses information from cases around the world -- and in particular the United States -- to advise doctors on how to diagnose, evaluate and treat diseases.

The federal agency possesses such information about several US coronavirus patients, but has not released it. That means doctors who now unexpectedly find themselves treating new coronavirus patients aren't able to benefit from the findings of doctors who preceded them.
