"What surprised us the most was that children carried very high viral loads in their airway secretions", she says, "loads that were higher than adults who are hospitalized for their severe COVID illness".
The findings from nose and throat swabs and blood samples carry implications for the reopening of schools, day care centres and other locations with a high density of children and close interaction with teachers and staff members.
"During this Covid-19 pandemic, we have mainly screened symptomatic subjects so we have reached the erroneous conclusion that the vast majority of people infected are adults". "I think we shouldn't make any assumptions that minimize the virus".
The study, which is a pre-proof that has been accepted for publication, in the Journal of Pediatrics concludes that children may be a "potential source of contagion" in the COVID-19 pandemic.
The researchers note that although children with COVID-19 are not as likely to become as seriously ill as adults, as asymptomatic carriers or carriers with few symptoms attending school, they can spread infection and bring the virus into their homes.
This is a particular concern for families in certain socio-economic groups and multi-generational households where children live with both their parents and grandparents, the researchers said.

"Kids aren't immune from this an infection and their signs don't correlate with publicity and an infection", she mentioned.

There also continue to be community exposure events at other locations and on flights into and out of the province. Lead image: A gentle reminder at the entrance to the Cranbrook Farmers' Market.
Alessio Fasano, a physician at MassGeneral Hospital for Children and one of the new study's authors, said that because children tend to exhibit mild symptoms or none at all, they were largely ignored in the early part of the outbreak and not tested. But they could not find solid evidence to prove that children are major contributors to the spread of the deadly virus that has already caused the death of more than 177,000 people in the United States. At least 97,000 kids tested positive for COVID-19 in the US during the last two weeks of July, marking a 40% surge in the country's cumulative total of child cases.
Complications from the accelerated immune response in the syndrome can include severe cardiac problems, shock and acute heart failure.
The study also looked at the immune systems of 18 children who developed MIS-C - a recently named condition linked to Covid-19 that scientists have been racing to understand it during the pandemic.
Five people are now in hospital in Saskatchewan related to the virus.
They say routine and continued screening of all students for coronavirus infection with quick reporting of results is crucial for safely returning to schools. "Kids are a doable supply of spreading this virus and this could be taken under consideration within the planning levels for reopening colleges".
The more recent data could mean that "kids have been silent spreaders, and more attention needs to be paid to this fact", Dr. Richard Watkins, an infectious disease specialist in Akron, Ohio, and a professor of internal medicine at the Northeast Ohio Medical University, tells Yahoo Life.
The study included 30 co-authors from the two hospitals, Harvard Medical School, Massachusetts Institute of Technology, Brigham and Women's Hospital and Harvard TH Chan School of Public Health. We hope that we have succeeded by giving you the full details and information.
