Time is running out to protect schools from becoming the epicenter of a fresh spike in COVID cases when class resumes in August.

The virulent Delta variant is now the dominant variant in the country and other countries have reported a surge in the share of cases in young people — and outbreaks in schools. Although total new U.S. cases have declined dramatically since the peak in January, young people now account for twice as large a share of new cases.

The Delta strain has been reported on the Navajo Reservation, the White Mountain Apache Reservation and locations throughout Arizona — with the number of new cases of the variant doubling and tripling every month. The virus in India has more easily infected young people and children and caused more serious illness, but still hits the elderly hardest.

Various studies suggest the Delta variant is roughly twice as easy to spread as the original strain. Moreover, one shot of the current vaccines provides only modest protection — while two doses provide excellent protection, according to recent studies. So far, only about 40% of Gila County residents are fully vaccinated.

That includes just 5% of those under 18, 26% of those aged 20 to 34 and 33% of those 35-44, according to state health services. This means school age kids and their parents have little protection against the onrushing Delta variant.

Fortunately, about 68% of those over 65 are fully vaccinated, which could explain why although new cases are on the rise, deaths continue to decline.

Nationally, 48% of Americans are fully vaccinated, including 59% of those older than 18 and 79% of those older than 65.

In the past two weeks, new infections have increased by 94% nationally to 7 cases per 100,000 population, with about 11,000 new cases reported daily. Hospitalizations have increased by 16%, but deaths have decreased 12%. The reported increase in new cases comes despite a 14% decline in the number of tests administered.

Arizona’s infection rate is 9 per 100,000, about 30% above the national average — and Gila and Apache counties all have rates close to the Arizona average. Navajo County is just above the state average at 11 per 100,000. Mohave County has the highest rate in the state — about 20 per 100,000. As a daily average in the past two weeks, the infection rate in Navajo County has risen 24% and the rate in Apache County has risen 30%. In Gila County, the rate has fallen 29%, as a daily average.

Nationally, Arizona has reported the eighth highest infection rate in the past two weeks.

Arkansas, Missouri, Florida, Louisiana, Alabama, Mississippi and Kansas have all reported a doubling or tripling of new cases in the past two weeks, with infection rates of between 10 and 27 per 100,000. That’s still far below the January peak, but much worse in most areas than a month ago before the Delta variant took hold.

It’s unclear whether the Delta strain will produce more serious illness. The variant has wreaked havoc in India and other countries, but that may reflect differences in the infection rate and the medical systems.

Fortunately, studies show that getting fully vaccinated with the Pfizer or Moderna vaccines provide strong protection against the Delta variant — and all the other “variants of concern.”

Unfortunately, the Delta variant appears better able to infect both those who have had only one shot and those who have recovered from an infection with the original strain and not gotten vaccinated, according to recent research. Last week, the Delta variant accounted for about 52% of new cases nationally. The Delta variant has not become dominant in Arizona yet, but experts say it’s only a matter of time.

This makes the effort to vaccinate kids 12 to 18 and their parents critical to the safe reopening of schools in August, say health officials. The federal Food and Drug Administration is expected to soon approve a vaccine for children 5-12, but the effort to convince parents to get children 12-18 vaccinated has been lagging — especially in Gila County. Statewide, some 13% of those 12 to 18 have received shots, with Gila County doing less than half as well.

The Arizona Legislature has barred mask mandates for students in schools, which means the vaccine remains the best way of preventing new cases on campus. Studies show that although children are less likely to get infected or seriously ill than adults, school campuses without mask mandates can still cause clusters of new infections.

So far, 4 million U.S. children have tested positive for COVID-19, about 14% of reported cases since the pandemic began, according to the American Academy of Pediatrics. In the past week, children have accounted for 23% of new cases, according to the federal Centers for Disease Control. So far in the pandemic, children have accounted for about 4% of hospitalizations and about 300 deaths — but those numbers may not hold up in the face of the Delta strain.

Schools cannot yet require children to get vaccinated to attend — as they can with many other vaccines. The existing vaccines have been approved for “emergency” use without the long-term studies of effectiveness and side effects other mandated vaccines have undergone. Nonetheless, Pfizer and Moderna have asked the federal FDA to give their vaccines regular use authorization, based on the safety and effectiveness data gathered in the field from the hundreds of millions of people vaccinated.

How about allowing the FDA to take off the no liability clause on vaccines if they are proven safe and not experimental any more before they try to make any vaccines mandatory????

Mr. Golembewski, could you please let us know where you get the idea that the vaccine will be made mandatory? I have heard of no such thing. Literally billions of people worldwide have received the vaccine and only a small handful of people have experienced complications. I have been vaccinated and am now immune to COVID. I have no desire for the government to make the vaccination mandatory, and I could not care less if you or others like you receive the vaccine or not. Feel free also to not wear a seatbelt when driving a car or to wear a helmet when driving a motorcycle.
