Delaware’s number of confirmed coronavirus cases now sits at 30, state officials announced Thursday.

Of those, 23 are from New Castle County, four are from Kent County, and three are from Sussex County.

Only three are hospitalized and one is critically ill.

State officials have stopped releasing details about each case and how the patient contracted the disease. All they would say is that the patients range in age from 14 to 80 and include 17 men and 13 women.

Symptoms of COVID-19, the disease caused by the new coronavirus, are most similar to lower respiratory infections with patients having fever, cough, and shortness of breath. There is no specific antiviral treatment recommended for COVID-19 infection at this time. While in some cases illnesses can be severe and require hospitalization, many individuals infected with COVID-19 recover by resting, drinking plenty of liquids and taking pain, and fever-reducing medications.

Testing for coronavirus disease is not recommended for individuals who do not have any symptoms of illness. For individuals who have symptoms of illness (fever, cough, or shortness of breath), they should contact their primary care provider, who can collect specimens and send them to either the Delaware Public Health Lab or LabCorp for testing. Medical providers should evaluate patients and rule out other causes of illness first before recommending testing for COVID-19.

While testing for the disease at the Public Health Lab requires DPH approval, providers do not need DPH approval to submit test samples to LabCorp. With the addition of commercial lab testing now available, Delaware has enough capacity to accommodate its current testing needs. Providers can use flu kits to collect a nasal swab for testing. Commercial labs are required to report testing and results to DPH.

DPH advises older Delawareans and people with severe chronic health conditions to follow guidance issued by the Centers for Disease Control and Prevention (CDC) encouraging them to "avoid crowds as much as possible" to reduce their risk of contracting coronavirus disease.

If you are in the higher-risk groups for getting very sick from COVID-19, the CDC recommends you should:

• Avoid non-essential travel such as long plane trips and defer all cruise trips worldwide.

• Avoid crowds, especially in poorly ventilated space, as much as possible.

• When you go out in public, including to doctor appointments or dialysis, keep away from others who are sick, limit close contact and wash your hands often.

• Take everyday precaution to keep space between yourself and others.

• If an outbreak does occur, stay home as much as possible.

• Stock up on supplies, including prescription and over-the-counter medicines, food and water, and other household items.

• Have a plan in the event you get sick, including discussing with household members, other relatives, and friends what you might need.
