Mayor Hardie Davis Jr. issued an executive order Friday mandating the use of face coverings in public places in Augusta, Georgia.
The executive order specifically requires the use of facial coverings or masks in all public places and government buildings in Augusta-Richmond county, a summary of the order posted to the mayor's Twitter account said.
"All persons entering a commercial establishment as a consumer, and all employees working in a commercial establishment (including but not limited to, restaurants, retail stores, salons, grocery stores, and pharmacies) in Augusta-Richmond County are required to wear a face covering while having face-to-face- interaction with each party," the order said.
The order does not apply to religious establishments, although they are encouraged to use face coverings and masks when engaging in religious activity, the order said.
If a person does not have a mask when entering a government building they will be provided one but if they refuse to wear it they will be denied entry to the building, according to the order.
More details: Face coverings are not required in certain situations, including during outdoor physical activity provided that all individuals at all times maintain a minimum of six feet between others they do not live with.
They are also not required while eating, drinking or smoking, or if a person is 10 years of age or younger.
There are currently 1,563 confirmed cases of coronavirus in Richmond County, according to the Georgia Department of Health website. Sixty people have died in the county and there are 256 people hospitalized, the website said.

Colombia's Ministry of Health reported a record number of new Covid-19 cases and deaths yesterday.
The ministry reported 6,803 new cases and 211 deaths on Friday. The new numbers bring the country's total number of Covid-19 cases to 140,776 and 4,925 deaths, according to health data.
Due to the recent surge in cases, authorities announced on Friday the implementation of new lockdown measures, based on geographic zones, for the capital city, Bogota, where most of the cases are reported.
Additionally, the national government announced the extension of the nationwide quarantine through August 1.
"Absolutely everything will be shut-down. We will suspend authorizations on all private construction happening in those locations – on any industries there, of trade and non-essential goods. In those locations, a 15-day quarantine will be imposed as we did at the beginning of the quarantine. Everyone will stay at home," Bogota Mayor Claudia Lopez said during a news conference on Friday.
Colombia is the fifth hardest hit country by the virus in Latin America following Mexico.

The US Centers for Disease Control and Prevention has updated guidance meant for public health officials and mathematical modelers, which now estimates that 40% of people infected with Covid-19 show no symptoms.
Back in May, the CDC created five "Covid-19 Pandemic Planning Scenarios," using data to provide a range of possible situations for Covid-19 in the US. The updated scenarios are based on new data the agency received through June 29. The agency also underscores these estimates are subject to change as more information becomes available, and exact numbers are uncertain.
Under the CDC's "current best estimate," 40% of people with Covid-19 are asymptomatic. This number is up from the 35% the agency estimated on May 20. The percent of asymptomatic cases remains uncertain, the CDC emphasized.
The CDC is now including an infection fatality ratio, which takes into account both symptomatic and asymptomatic cases (in the estimates published in May, the agency only included fatality ratio for symptomatic cases). Under the "best estimate" scenario, the infection fatality ratio is 0.65%, meaning that 0.65% of people infected with Covid-19 are thought to die.
More insight: About half of Covid-19 transmissions happen before people get sick; this is up from the 40% estimate in May.
Under the CDC's current "best estimate," the transmissibility of the virus from asymptomatic people -- in comparison to people with no symptoms -- is now 75%, down from 100%. However, the agency said this "remains highly uncertain as asymptomatic cases are difficult to identify and transmission is difficult to observe and quantify."
The agency warns this information is "intended to support public health preparedness and planning."

No one is immune to this deadly disease, but we each have the power to impact the path this pandemic takes in South Carolina."
