Amid coronavirus concerns, Publix aims to be that place "where shopping is a pleasure."

Less than a week after the Lakeland-based grocery chain announced it would close its stores two hours early to restock and clean, Publix released times and days for "senior shopping hours." Older adults and those with underlying health conditions are more susceptible to COVID-19.

The company issued a statement Thursday: "Publix is designating Tuesday and Wednesday mornings, 7 to 8 a.m., as senior shopping hours for customers age 65 and over. This change in hours will begin Tuesday, March 24, and continue until further notice. Publix Pharmacy will also be open at 7 a.m. on Tuesdays and Wednesdays to serve our senior population."

As of Thursday afternoon, the total number of confirmed COVID-19 cases in Florida increased to 390, with eight deaths, according to the state Department of Health. The greatest percentage of cases continues to be reported in those 50 and older.

"According to the CDC, individuals over the age of 65 are at increased risk of complications from the coronavirus. Publix is offering these expanded hours to better support our elder community," the company stated in a news release.

With the increase of coronavirus cases, the grocery chain has not been immune to panic buying. The novel coronavirus sparked a nationwide shopping frenzy, with readers sharing photos of empty shelves and produce bins on social media.

On March 13, Publix announced it would close two hours earlier to give staff time to clean and restock their shelves: "To better serve our customers, give our store teams time to conduct additional preventive sanitation and restock product on our shelves, beginning Saturday, March 14 we will adjust store and pharmacy hours companywide to close at 8 p.m. until further notice."
