Tampa, Fl. – Local Tampa Bay area doctors and health experts are concerned about Delta variant continuing the cause hospitalizations on the community who is unvaccinated.

While coronavirus deaths and hospitalizations have plummeted in Florida, the CDC said this week nearly every death now, due to COVID-19, is preventable.

Tampa General Hospital's Dr. Andrew Myers is the Director of their COVID-Care unit.

Dr. Myers said, currently, the Delta variant does not make up the majority of their hospitalizations.

But he predicted it will soon be the dominant strain in their ICU.

Dr. Myers said it’s more virulent a mutation than the other variants.

"It spreads much more easily and people seem to get sick more quickly and get sicker from what we've seen,” said Dr. Myers.  “It's only been around for about a few months a little longer and coming here to America we've only been seeing for the last month or two.  But it does seem to be able to spread much more easily so it's that much more dangerous for people who aren't vaccinated."

The CDC published more evidence that hospitalizations and severe outcomes are happening to people who are unvaccinated.

On Friday, the CDC posted new data of breakthrough cases.

These cases happen when someone vaccinated still has a COVID-19 infection.

As of June 21st, more than 150 million people had been fully vaccinated.

Of those, 4,115 were hospitalized from contracting the virus and 750 have died.

There were more than 18,000 deaths in the month of May alone.

Meaning he overwhelming number of hospitalizations leading to a fatal outcome were made up of people who were unvaccinated.

The CDC also said about 76% of hospitalizations and deaths from breakthrough cases occurred in people over the age of 65.
