Several infected after convention touting ivermectin; some hospitals overwhelmed ahead of Thanksgiving holiday: Latest COVID-19 updates – USA TODAY

Several peoplewho attendedaconference in Floridaearlier this month where ivermectin was promoted as treatment against COVID-19 have since contracted the virus.

Dr. John Littell,the Ocala-based physician who organized the Florida Summit on COVID at an equestrian center Nov. 6, said one physician got sick and that a "handful of others" had mild cases.

The Food and Drug Administration says ivermectin is approved to treator prevent parasites in animals. For humans, ivermectin tablets are approved to treat some parasitic worms, and there are topical formulations for head lice and skin conditions. The FDA has not authorized ivermectin for use in preventing or treating COVID-19 in humans or animals.

Littell, who is unvaccinated and believes ivermectin is effective at treating and preventing the virus, said he does not believe the infections were spread at the conference.

"Only one physician got sick and that's because his father had been ill in the Florida Keys before he came," Littell said. "In each case, everyone is healthy now and back in the saddle. And all were given early treatment and ivermectin and the usual combination of therapies."

The majority of cities and towns in Connecticut are now in the red alert level, the state's highest of four levels for COVID-19 infections, according to state data released Wednesday.

Of the state's 169 municipalities, 110, or 65%, were in the red zone the most since April 22.

Democratic Gov. Ned Lamont on Tuesday urged residents to take steps to protect themselves, noting New York, Massachusetts, Rhode Island and Vermont had higher rates of infection than Connecticut.

That's just a reminder that we're not an island. That's why we've got to continue to be very cautious, he said.

Dozens of Tennessee health care, higher education and consulting entities applied for an official exemption last week from the states new law that strictly curtails businesses from enacting COVID-19 restrictions.

The legislation, signed into law earlier this month by Gov. Bill Lee, prohibits most private businesses from requiring COVID-19 vaccines or proof of vaccination. But the bill carved out a provision for entities at risk of losing major federal funds if they followed the new Tennessee law, such as federal contractors, transportation authorities and health care providers that treat Medicare or Medicaid patients.

The Tennessee comptroller began accepting exemption applications Nov. 15 and received 76 by the end of the week, though legitimate applications were slightly less due to some duplicate and errant submissions.So far, denials have been rare.

Of the 76 applications, five were denied and 44 are awaiting approval.
