A young man whose bold defiance of social distancing guidelines while on spring break in Miami drew widespread attention — “If I get corona, I get corona,” he declared in a television interview — apologized this week for his comments.

“I wasn’t aware of the severity of my actions and comments,” the man, Brady Sluder, said on Instagram on Sunday. “I’d like to take this time to own up to the mistakes i’ve made and apologize to the people I’ve offended.”

Mr. Sluder, who The Associated Press said is 22 and lives in Milford, Ohio, said in the post that he, like many people, has “elderly people who I adore more than anything in the world and other family members who are at risk.”

In a caption accompanying the post, Mr. Sluder said he “can’t apologize enough,” and that he wants to “use this as motivation to become a better person, a better son, a better friend, and a better citizen.”
