Older Children Spread the Coronavirus Just as Much as Adults, Large Study Finds

The study of nearly 65,000 people in South Korea suggests that school reopenings will trigger more outbreaks.

-0-

In the heated debate over reopening schools, one burning question has been whether and how efficiently children can spread the virus to others.

A large new study from South Korea offers an answer: Children younger than 10 transmit to others much less often than adults do, but the risk is not zero. And those between the ages of 10 and 19 can spread the virus at least as well as adults do.

The findings suggest that as schools reopen, communities will see clusters of infection take root that include children of all ages, several experts cautioned.

“I fear that there has been this sense that kids just won’t get infected or don’t get infected in the same way as adults and that, therefore, they’re almost like a bubbled population,” said Michael Osterholm, an infectious diseases expert at the University of Minnesota....

WHO posts 2nd daily record for new cases in row

The World Health Organization is again posting a single-day record of new confirmed coronavirus cases. It announced 259,848 new cases on Saturday.

The WHO on Friday posted more than 237,000 confirmed cases around the world. The back-to-back records come as many nations struggle with new waves of infections after loosening lockdown restrictions.

WHO’s list of guidance on COVID-19

There’s a lot of information out there about how governments, health professionals and the general public should respond to the COVID-19 pandemic. WHO has published guidance and advice every step of the way. 

During health emergencies like the COVID-19 pandemic, one of WHO’s most vital roles is to gather data and research from around the world, evaluate it, and then advise countries on how to respond.

Coronavirus has been detected on particles of air pollution by scientists investigating whether this could enable it to be carried over longer distances and increase the number of people infected.

The work is preliminary and it is not yet known if the virus remains viable on pollution particles and in sufficient quantity to cause disease.

The US is rolling out digital contact tracing. How has it been working in other countries?

vox.com - by Shirin Ghaffary - April 18, 2020

If and when lockdown restrictions are lifted in the US, would you agree to let the government anonymously track your interactions with people within a 6-foot radius to control the spread of Covid-19?

That’s an increasingly urgent question as President Trump and state governors debate how and when to safely reopen the US economy — and as technology is being touted as a solution that would help people reenter public life.

And tech giants are stepping up. Last week, Apple and Google announced a plan to turn phones into opt-in Covid-19 tracking machines that would, if all goes as planned, make it easier for health officials to identify and alert people if they’ve been exposed to the virus.

CCDS - Critical Care Decontamination System - Uses Hydrogen Peroxide Vapor to Decontaminate N95 Respirators, and Other PPE

           

Battelle Memorial Institute's CCDS Critical Care Decontamination System uses a hydrogen peroxide vapor to decontaminate N95 respirators. The organization says that the process takes about 2½ and that masks can be cleaned and reused up to 20 times.Battelle Memorial Institute

Late Monday, the Pentagon announced a $415 million contract to commission 60 decontamination systems that will allow millions of highly protective N95 face masks to be reused.

The system, which can process up to 80,000 masks per day, has been called a potential "game changer" for the front-line health care workers and first responders who rely on the masks, according to hospital officials concerned about a shortage of protective equipment to shield their staff from COVID-19.

But the story of how this system came to be is a testament to what can happen when a doctor and an engineer — who happen to be husband and wife — ask, "What if?"
