UPDATE: The first Tennessean diagnosed with COVID-19 traveled on a roundtrip, nonstop flight to Boston, Massachusetts from Nashville International Airport, the Tennessee Department of Health (TDH) confirmed in a news release.

The patient was asymptomatic while traveling, but currently has a mild illness and is isolated at home.

TDH said they're in close contact with the Massachusetts Department of Public Health and Nashville International Airport CEO Doug Kreulen, a coronavirus task force member, about this case.

TDH will announce the test results of household contacts of the COVID-19 patient as well as any additional positive test results.

TDH launched a coronavirus hotline for public information, available 10 a.m. to 10 p.m. CST every day. The number is 877-857-2945.

The Chattanooga-Hamilton County Health Department also activated its coronavirus (COVID-19) information hotline for general questions and planning assistance, available at 423-209-8383.

PREVIOUS STORY: Hamilton County Mayor Jim Coppinger held a news conference Thursday to address coronavirus. He and other officials outlined the preparations already in place within the county.

Mayor Coppinger said state and local governments have been meeting for weeks to prepare for the day coronavirus comes to the area.

Hamilton County Health Department Director Becky Barnes says there are currently no cases of coronavirus within Hamilton County, but they are anticipating future cases.

Barnes says the department is in close communication with the CDC and Department of Health and monitors the health of travelers.

The department has created a resource team to provide education and planning assistance to businesses, schools, faith-based institutions, restaurants and colleges.

Hamilton County Emergency Management and Homeland Security Director Chris Adams advised people to scrub hands for at least 20 seconds and have a kit with 30 days of medication prepared.

Adams said dispatchers were trained on screening travelers.

Hamilton County Schools Superintendent Dr. Bryan Johnson said student safety is the top priority and is working with the health department to create a plan for treatment of the virus.

Dr. Johnson encouraged parents to keep sick students at home and to be fever-free for at least a day.

Dr. Johnson said all high-contact areas in schools are being sanitized, including water fountains, sinks and doorknobs.

Health Department Manager of Epidemiology Beth Fulbright explained the process of monitoring travelers.

Fulbright said healthy people who have traveled to infected countries will be monitored for 14 days.

During monitoring, people are interviewed, self-quarantined, checked daily and required to notify the health department if they develop symptoms.

Fulbright said three to four people are being monitored.

PREVIOUS STORY: Tennessee Gov. Bill Lee shared the news Thursday morning that the state has its first confirmed case of coronavirus, COVID-19.

The patient's diagnosis was confirmed Wednesday.

The 44-year-old Williamson County man traveled outside the state and is working with officials to complete his travel history to better track possible exposure to others.

Tennessee Department of Health Commissioner Lisa Piercey said the man did not travel internationally. 

Piercey says he's isolated at home with mild symptoms and his household contacts are being evaluated, Piercy said.

Tennessee epidemiologist Mary-Margaret Fill said the patient began feeling ill shortly after returning from out-of-state travel and had very limited activity outside his home.

Piercey said the threat to the general public in Tennessee is low. She encouraged people to take common-sense precautions like hand washing.

"While this is a serious situation, I urge Tennesseeans to keep this illness in perspective as the vast majority of cases are mild and manageable," Gov. Bill Lee said. 

The Tennessee Department of Health said they have tested multiple patients in the state since February with all negative results.

Officials added the risk to the general public in Tennessee remains low.

This is a developing story and will be updated.
