Raleigh, N.C. — Health officials say that you should be looking closely at the number of fully vaccinated people in your area as the newest strain of coronavirus is rapidly spreading. The US is now averaging more than 16,000 new COVID cases per day, an increase of more than 21% in just the last week.
The Centers for Disease Control and Prevention says that the Delta variant of the COVID-19 virus is about 40% to 60% more transmittable than the initial strain of COVID-19. These cases continue to surge among unvaccinated populations in the South.
People who are living in areas with low vaccination rates — even if they are vaccinated — could be at risk of getting infected, said emergency physician Dr. Leana Wen with George Washington University's Milken Institute School of Public Health. Breakthrough infections are possible even after someone is vaccinated, though research shows coronavirus vaccines are almost entirely effective at preventing severe illness or hospitalization.
In most North Carolina counties outside of the Triangle, less than 50% of residents are fully vaccinated. Wake, Orange and Durham counties have more than half the population vaccinated, but Johnston, Wilson and Harnett counties have vaccination rates under 40%.
Only 26% of Cumberland County residents are fully vaccinated. Hoke County, south of the Triangle, has a vaccination rate of 21%. Those counties also report high vaccine hesitancy rates.
Dr. Anthony Fauci, the nation's top infectious disease expert, said this month that if someone is in a community where not many people are vaccinated, it may be appropriate to mask up.
"If you are an elderly person, or if you have a person with an underlying disease, you might want to go the extra mile of protection of wearing a mask if you were indoors, in an environment with a high degree of infection in the community, and a low level of vaccinations,” he said on July 8 during a White House coronavirus briefing.
State health officials say the Delta strain has accounted for nearly 30% of coronavirus infections in recent weeks – and they expect that number to rise. Since May, more than 99% of new COVID cases in the state are among those who are not fully vaccinated.
If the Delta variant continues to spread, and vaccination rates don't increase, masks and social distancing could return, experts say. New COVID cases in North Carolina have jumped 52% over the past week.
Vaccinations in North Carolina have mostly stalled at around 50%, which is below the national average. Experts believe immunity is achieved when more than 70% of the population is protected from the virus with a vaccine.
Recent polling shows that young adults and Republican women are holding out on getting the vaccine. More than 45% of Republican women do not plan to get vaccinated or are uncertain, Morning Consult polling says. That number is 15 points higher than all adults, and 13 points higher than Republican men.
Coronavirus vaccinations in NC
Around 20% of young adults, ages 18 to 34, say they are uncertain on getting the coronavirus vaccine. State data shows that only 53% of people 18 years and older are vaccinated, compared to 80% of people 65 years and older.
More young people are now having to be hospitalized with COVID-19 as the Delta variant spreads. Medical experts are seeing that the Delta variant is more severe, and attacks patients faster than the previous strain of COVID.
In Missouri, only about 40% of the population is fully vaccinated. About 91% of the patients in the intensive care unit at Mercy Hospital in Springfield are on ventilators, Chief Administrative Officer Erik Frederick said. The majority of them are young adults.
"That is shocking to us, to have that kind of number," Frederick said Saturday. "These are young patients -- you have them in their 20s, 30s, 40s -- again, it's alarming, (and) a direct line to the vaccination rates."
