“As we do expand testing capability, we will find more cases, and the caseload will grow,” Health Commissioner Gary Cox said.

Cox said there is no treatment to cure COVID-19, but he said 80% of the cases are expected to be mild, with symptoms that can be managed adequately at home. Further care may be needed for the most serious conditions, he said.

Cox said officials have been discussing surge capacity at medical facilities to ensure that they are prepared to respond as needed.

Meanwhile at the Capitol, some Senate personnel were being tested after someone tested positive for COVID-19, according to a message sent to senators and staff.

It was not immediately clear whether the person was a senator or a staff member.

“While risk to a majority of senators and Senate personnel remains low, out of an abundance of caution, we are sending health professionals to each office to get a swab,” the Senate’s chief operating officer, Arnella Karges, said in a message sent internally at 11:25 a.m. Tuesday.

The message said those who might have come into contact with someone who has tested positive likely would receive phone calls from health professionals with information about how to protect themselves and others.
