Kids aren’t just tiny adults. Their bodies deal with COVID differently.
And what *does* COVID do to our bodies, anyway?
Study Shows Flu Vaccine Lessens COVID-19 Symptoms in Children (University of Missouri School of Medicine, 02.04.21)
“‘[T]he growth of one virus can be inhibited by a previous viral infection,’ said Anjali Patwardhan, MD, professor of pediatric rheumatology and child health. ‘This phenomenon is called virus interference, and it can occur even when the first virus invader is an inactivated virus, such as the case with the flu vaccine.’”
The B.1.1.7 Variant
The NY Times, 12.31.20: “The new variant seems to infect more people than earlier versions of the coronavirus, even when the environments are the same. . . . it is likely to catch on rapidly and become the predominant form in the United States by March.”
The NY Times, 02.13.21: Aaaand it’s probably slightly deadlier. Great.
What Does a More Contagious Virus Mean for Schools?
(NY Times, 01.14.21)
Current research is shows that the B.1.1.7 variant of COVID is about 30 – 50% more transmissible than its predecessors. But young children are about half as likely to spread it as adults are. Kids ages 10 to 19 fall between littles and grown-ups in terms of their ability to transmit it.
What it means for schools: Mitigation measures will still work. We just have to adhere to them more strictly than ever.
The body’s fight against
COVID-19 explained using
(The Conversation, 01.26.21)
“Nathan Ahlgren, assistant professor of biology at Clark University, uses 3D-printed models to explain what proteins do in viruses, how they interact with human cells, how the vaccine delivers mRNA into the cell, and how antibodies protect us.” Includes video.
Kids Under 15 Catch and Spread COVID Half as Much as Adults
(National Geographic, 12.10.20)
A 40,000-person study in Iceland “found that children under 15 were about half as likely as adults to be infected, and only half as likely as adults to transmit the virus to others. Almost all the coronavirus transmissions to children came from adults. . . . But even if children are generally less susceptible, when infection surges in a community, the risks in schools can dramatically increase.” (emphasis added)
Being Vitamin D-deficient
isn’t good, especially if you get COVID. (The Guardian, 01.10.21)
It’s not clear if taking a lot of Vitamin D helps fight COVID. But there’s a lot of evidence that having too little of it keeps people from fighting it well. That’s especially important for folks with darker skin who live in northern climates, who often don’t get enough Vitamin D.
What Is COVID Doing
To Our Hearts?
“The disease may damage cardiac muscle even in those who never displayed symptoms.” The damage can become apparent in either the short or the long term. For this reason, the American College of Cardiology recommends that all kids who’ve had COVID (except those under age 12 who had mild cases) be checked out by a doctor before doing any strenuous physical activity.)
Most Infected Folks Shed Virus
for About a Week
(NY Times, 11.29.20)
“People with Covid-19 . . . are most infectious about two days before symptoms begin and for five days afterward, according to a new analysis of previous research.”
When Is a COVID Patient
(The Lancet Microbe, 11.09.20)
According to this scientific paper, it’s between Day 0 and Day 5 of infection.
The Children Never Had the Coronavirus. So Why Did They Have Antibodies?
(NY Times, 11.10.20)
A study suggests that certain colds may leave antibodies against the new coronavirus, perhaps explaining why children are more protected than adults.
For folks who read scientific journal articles. Median incubation time; shorter incubation –> more severe disease; and just because you test positive doesn’t mean you’re infectious
How an Ill-Fated Fishing
Voyage Helped Us Understand Covid-19 (NY Times, 10.20.20)
The finding is believed to be the first direct evidence that antibodies protect against SARS-CoV-2 infection in humans, and it offers clues about what sort of concentrations might be needed to confer immunity.
Young Children Are Less Likely to Transmit Virus Than Teens
or Adults (Nature, 10.29.20)
The younger the kid, the less likely they are to transmit virus. That’s why schools – especially elementary schools – are less likely to be the source of outbreaks than other places where people gather.
