As the virus spreads and testing capacity has ramped up, the number of confirmed cases has multiplied. As of Wednesday, nearly 9,000 tests had been conducted across the state, and about 17% of those returned positive results.

The state’s lab conducted 164 new tests since late Wednesday, according to the health department.

Still, amid a nationwide scarcity of test kits and supplies, Georgia continues to ration testing to those most at risk of infection. According to health experts, it is likely the number of COVID-19 cases in Georgia is 5 to 10 times higher than those confirmed by the state.
