A Florida man who tested positive for COVID-19 and was busted along with his wife in Key West for allegedly violating a quarantine order insisted Friday he was just walking their dog and not trying to endanger anyone.

I didnt do anything, 24-year-old Freire Interian told The Associated Press. I was just walking my dog. Its not as if I left the house to go shopping.

Interian spoke out as the coronavirus continued to cut a deadly swath through Florida with the state breaking its daily death record for the fourth day in a down with 257 new fatalities, according to the latest NBC News tally.

The numbing new figure was reported on the heels of Florida notching 253 deaths on Thursday, 216 on Wednesday, and 186 more on Tuesday — all of which were new daily highs in a pandemic has turned the state into a COVID-19 hot spot.

Meanwhile, Florida was being menaced by Hurricane Isaias and Gov. Ron DeSantis declared a state of emergency from Miami-Dade County all the way up the states Atlantic coastline a stretch that includes the counties with the biggest numbers of COVID-19 cases and deaths.

As of Friday, Florida has reported 470,386 cases and 6,843 fatalities.

Nationwide, more than 4.5 million confirmed coronavirus cases have been reported along with 153,480 deaths, the NBC News figures show.

Interian was arrested along with his 27-year-old wife Yohana Anahi Gonzalez on Wednesday after neighbors videotaped them allegedly flouting the quarantine requirement, local officials have said.

They were each hit with misdemeanor charges of violating the state law that requires isolation or quarantine in a public health emergency and with violating emergency manages, conviction on which could send them both back to jail for up to 60 days.

Calling his arrest unfair, Interian said he was stunned when the Key West Police arrived at the house he shares with several other people.

They knocked on the door real loud, he said. I opened the door. They told me, Come on, and I asked them, Why? I was in shock.

Florida health officials, however, say Interian and Gonzalez learned they were infected on July 15 and were supposed to self-isolate for 14 days. But on July 20 they ventured out to a store and were caught doing so on video.

Interian and Gonzalez appear to be among the first people to be arrested in Florida for breaking quarantine. But they arent the first to run afoul of local quarantine regulations.

In Hawaii last month, 21 travelers were arrested for breaking the states mandatory 14-day quarantine, none of whom wound up testing positive. And in May, a 37-year-old Kentucky woman infected with COVID-19 was charged with wanton endangerment and criminal mischief after she was caught shopping for groceries while she should have been in isolation. It was the third time she had defied a quarantine order.

In other coronavirus-related developments:

  • Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, told a Congressional committee he was “cautiously optimistic” researchers will have honed in on a safe and effective COVID-19 vaccine by the end of this year. He also sparred with defenders of President Donald Trump, like Rep. Jim Jordan, R-Ohio, who tried to get Fauci to link the exploding number of new coronavirus cases to ongoing protests against police brutality that erupted after George Floyd died while in Minneapolis police custody. So far there doesn’t appear to be any evidence the protests are behind the virus spikes. The majority of medical experts says states like Florida, Texas and Arizona reopened before the coronavirus could be contained and are now paying the price. Trump, who has been criticized for downplaying the danger of the pandemic, tweeted out his approved of Fauci’s hopeful news and Jordan’s pitbull questioning of the doctor.
