Filming Leventhal, Dodd said, "So, we tested positive for Lyme disease."
"I've never had contact with a tick in my life," she added.
While Dodd said this is the first time she's contracted Lyme disease, Leventhal shared that he's previously had Lyme disease twice.
Leventhal, who was sitting across the table from Dodd, then took an antibiotic pill. The Fox News reporter pointed out that the medication cured his past bouts with the disease.

Dodd, 45, didn't reveal where she and Leventhal, 61, believe they contracted Lyme disease. However, the couple -- who married last October -- had just returned from a trip to Turks and Caicos on Sunday.
The Bravo star posted a series of photos from their trip to Instagram on Sunday.
"Bye bye Turks & Caicos 😢we had the best time!" Dodd captioned the post, above.
Lyme disease -- which is caused by four main species of bacteria -- is transmitted by a deer tick bite. The illness can cause a wide range of symptoms including rash, swollen lymph nodes, body aches, fever, chills, fatigue and neck stiffness, according to Mayo Clinic. However, if untreated, more severe symptoms may appear, such as joint pain and neurological problems.
