Virginia authorities are reporting more than 460 new cases of COVID-19, the largest one-day increase so far in the coronavirus pandemic.
The numbers released Friday by the Virginia Department of Health now show more than 4,500 positive tests for the coronavirus in the state.
The death count has increased from 109 to 121.
The increase in cases is in part a function of increased testing.
But state and federal authorities have expressed concern that the D.C. metropolitan area could become a national hotspot for COVID-19 cases.
That includes the northern Virginia suburbs, which account for more than 40 percent of state cases.
