ORIGINAL STORY [noon]: The number of confirmed coronavirus cases in Georgia has more than doubled in the past five days, from just over 2,000 cases Friday to more than 4,500 Wednesday.

There are now at least 4,638 cases and 139 deaths statewide, according to the latest data from the Georgia Department of Public Health. Fourteen more Georgians have died since Tuesday night as a result of COVID-19, the disease caused by the novel coronavirus.

The count increased about 35% between Monday and Tuesday, and the latest figures represent an increase of about 13% Wednesday. Additional growth is expected when the Department of Public Health releases its next update at 7 p.m.

Of those who have tested positive for COVID-19, 952 are hospitalized Wednesday, according to the health department.

Officials say those numbers are not an accurate depiction of the crisis in Georgia with the state still rationing its limited supply of test kits to the most vulnerable. Between commercial and state laboratories, 4,145 new tests were conducted since late Tuesday night.

Within the next week, Gov. Brian Kemp has said he hopes to increase testing capacity by 3,000 tests per day.

Fulton and Dougherty counties reported the largest increases Wednesday. Dougherty, which is home to Albany and has become an epicenter of the coronavirus crisis in Georgia, confirmed 14 more cases of COVID-19 and one more death since Tuesday night.

The much larger Fulton County also reported an additional death, as well as 25 new cases. The other deaths Wednesday came from Cobb, Gwinnett, Bartow, Bryan, Calhoun, Cherokee, Douglas, Houston and Ware counties. They were the first for Bryan, Calhoun and Ware.

Of the deaths statewide, about 62% had underlying conditions and 74% were age 60 or older, according to health officials. More men than women have died of COVID-19.

For most, COVID-19 causes only mild or moderate symptoms. Older adults and those with existing health problems are at risk of more severe illnesses, including pneumonia. The vast majority of people recover in a matter of weeks.

Those who believe they are experiencing symptoms or have been exposed to COVID-19 are asked to contact their primary care doctor or an urgent care clinic. Do not show up unannounced at an emergency room or health care facility.

Georgians can also call the state COVID-19 hotline at 844-442-2681 to share public health information and connect with medical professionals.
