Virginia officials still are investigating the James City death, but so far have not been able to determine how the man was initially exposed.

“We were unable to find any source of exposure and it’s that case that makes us concerned for the likelihood of community spread,” Oliver said.

Officials said they are working on containment and tracing the 284 contacts the patient may have had after infection.

As of Sunday evening, 45 people had tested positive in Virginia for the coronavirus.

The four new cases announced on Sunday were spread over Alexandria, Arlington, Prince William and Virginia Beach, which all had at least one case already.

Officials said the state currently has the capacity to test from 370 to 470 individuals, with more test kits on the way, and private entities in the state have now added to the state’s capacity.

Northam suggested that businesses engage in social distancing practices, such as spacing out customers eating in restaurants.

Northam said there can be a reforecast of the final budget before signing if needed but he does not anticipate the state legislature needing to meet again to pass relief legislation before the scheduled session next month.
