Just weeks into the federal government’s efforts to contain the novel coronavirus, a new California case has exposed weaknesses in the testing procedures that could be masking more widespread reach of the disease.

A woman in Solano County, California, who hadn’t traveled abroad or had contact with another known patient with the illness was diagnosed with the virus Wednesday, raising concerns that cases are going undetected because of the federal government’s narrow testing protocols.

The patient sought care at a local hospital before being transferred to UC Davis Medical Center in Sacramento because of the severity of her case, according to a letter hospital officials sent to members of the campus community. Suspecting coronavirus, doctors at UC Davis asked public health officials about testing for COVID-19, the name given to the illness believed to have originated in Wuhan, China.
