US coronavirus: More students go back to school as Covid-19 cases rise among children and at colleges

September 9, 2020 steven

Most of the biggest districts reopening Tuesday are starting the school year online only. But some will have students in classrooms — subjecting students and teachers to an experiment that has had mixed results so far.

More than 476,000 children have infected with coronavirus as of August 27, according to the American Academy of Pediatrics and the Children’s Hospital Association. In the last two weeks of the study, the number of child cases jumped by 70,330.

Waiting for outcomes from Labor Day weekend

One big factor that could impact how rampantly Covid-19 spreads this fall is the outcomes from Labor Day weekend celebrations.

We won’t know the effects of Labor Day behavior for weeks. It takes up to 14 days for newly infected people to develop symptoms, and any new hospitalizations or deaths typically happen days or weeks after that.

Why the course of this pandemic largely hinges on Labor Day behavior

To avoid mistakes made during the Memorial Day and July Fourth holidays, many Americans opted to stay home or socialize safely this Labor Day weekend. Others weren’t as cautious.

In Brooklyn, authorities shut down a bar over the weekend after deputies found nearly 300 people packed inside, CNN affiliate WABC reported. In Nashville, thousands flocked to the bars operating with restrictions, prompting the mayor to close down portions of a road to allow for more social distancing, CNN affiliate WKRN said.

In Rehoboth Beach, Delaware, crowds of visitors made social distancing nearly impossible, visitor Kristin Lefebver told CNN affiliate WBOC.

“In general I thought crowds were down this summer, until we hit Labor Day weekend,” Lefebver said. “As far as walking along the avenue, walking along the beach, being in the ocean, we’re quite on top of each other this weekend.”

Vaccine makers’ pledge could quash Trump’s claim

Despite President Donald Trump’s repeated claims that vaccines could be rolled out by Election Day, more health experts are saying that’s unrealistic.

“The reality is I do not see a way that we will have enough data for our Data and Safety Monitoring Board to say we have a vaccine, we can approve it, and it’s ready to roll put before Election Day,” said Dr. Carlos del Rio, a professor at Emory University School of Medicine and one of the investigators for the Moderna vaccine.

“This seems to be more of a political stunt than a public health gain. And we need to focus on the science … and let science drive the process.”

9 vaccine makers sign safety pledge in race for Covid-19 vaccine

Moderna is one of nine vaccine makers that has issued a joint pledge Tuesday vowing to not cut corners in terms of safety just to get a vaccine out.

The pledge comes after US Food and Drug Administration Commissioner Dr. Stephen Hahn told the Financial Times that the FDA could consider emergency use authorization or approval for a Covid-19 vaccine before critical Phase 3 trials are complete.

The nine companies promised they would “Only submit for approval or emergency use authorization after demonstrating safety and efficacy through a Phase 3 clinical study that is designed and conducted to meet requirements of expert regulatory authorities such as FDA.”

Many health experts have said a safe and effective Covid-19 vaccine might not be publicly available until 2021.

What to do before a vaccine

Doctors worry that as the weather cools down, more Americans might start socializing indoors — where coronavirus can spread more easily.

One easy way to minimize the spread is with face masks. If 95% of Americans wore face masks consistently, about 70,000 lives could be saved between August and December, according the University of Washington’s Institute for Health Metrics and Evaluation.

The problem is not everyone is heeding that message, IHME Director Dr. Christopher Murray said.

“We’re seeing a rollercoaster in the United States,” Murray said.

“It appears that people are wearing masks and socially distancing more frequently as infections increase, then after a while as infections drop, people let their guard down and stop taking these measures to protect themselves and others — which, of course, leads to more infections. And the potentially deadly cycle starts over again.”

The effectiveness of face masks is obvious in countries that have lower rates of Covid-19 deaths than the US does, said Dr. Jonathan Reiner, a professor of medicine at George Washington University.

“When you look at countries where the mortality is a fraction of what it is in the United States, the common theme from the very beginning of the pandemic was universal masking,” he said.
