Restaurants and other businesses across the island are being heavily impacted by the coronavirus outbreak.

The state mandated that restaurants, bars, movie theaters and other venues that hold fewer than 500 people cut their capacities in half.

Suffolk Executive Steve Bellone announced Saturday that Jake's 58 Casino would be temporarily shut down to help stop the spread of the virus.

Maureen's Kitchen, of Smithtown, is seeing a significantly lower amount of customers than it usually gets, according to the owner, Kevin Dernbach.

Dernbach says he's doing everything to keep customers and staff safe, such as removing tables to help customers keep their distance from each other, and constant sanitizing. Even so, he says the business is suffering.

"It hurts. It's hurting everything. It hurts our staff, shorter hours for our staff. It a trickle down. It hurts everybody," he says.

Shoppers flocked to Costco in Commack Sunday morning, hoping to stock up on food and other items in case they are quarantined.

The most popular items were bottled water and paper towels, although plenty of people were spotted leaving with eggs, meat and other essential food items.

Notably missing was toilet paper, which has been completely wiped off the shelves at so many stores on Long Island, and across the country.

Health officials are advising that people distance themselves from one another to slow the spread of the disease.
