Overall, Covid-19 cases, hospitalizations and deaths in the US have declined significantly in recent months.

But virus variants, particularly the Delta variant, have been a top concern for many experts when it comes to those who remain unvaccinated against the coronavirus.

The Midwest and South lag in vaccination rates compared to coastal states, with Alabama, Louisiana, Mississippi, Tennessee and Wyoming among the slowest to vaccinate.

In Missouri, where 43.4% of the total population is at least partially vaccinated, the Delta variant is on the rise.

"Much of the South, Midwest, much of the places that have low vaccination rates -- if confronted with the Delta variant, will see a similar kind of surge of patients as we're beginning to see right now."

As of Friday, 44.7% of the total US population has fully been fully vaccinated while 53.1% received at least one dose of a vaccine, according to data from the US Centers for Disease Control and Prevention.

"We have to really pick up the pace in the South, or we're going to see a lot of people die who just simply don't need to die."

There are other variants, too

The dangers of the Delta variant cannot be overstated.

But several have shown the ability, both in laboratories and in real life, to re-infect people who recovered from natural coronavirus infection and to infect people who have been only partially vaccinated.

Fully vaccinated people had a strong and broad immune response that should take care of the variants, vaccine experts have agreed.

The Gamma variant has become common in Rhode Island, where it comprises 20% of all variants, according to Dr.

"If you're not vaccinated or if you've only got a single dose of vaccine, you have vulnerability," said Hotez, the dean of the National School of Tropical Medicine at Baylor College of Medicine.

Covid-19's potential effects on the brain

A United Kingdom study found that some people who have been infected with Covid-19 experienced loss of gray matter in the brain, especially in areas affecting smell and taste.

The researchers, who are from the University of Oxford and the Imperial College, compared brain scans of 782 people who have been volunteering as part of a larger study and who had MRIs three years apart -- before and after the pandemic.

Those who had Covid-19 had evidence of a loss of brain cells compared to similar people who had not been infected, the study found.
