New study in direct contrast to guidance from March, offered yesterday by @JOCOHealth, regarding child-to-child transmission as well as child-to-adult infectiousness being low. @theSMSD @davidasmithkc @sanmiareola @MikeFultonSMSD @doclemaster @SecNorman @EpiElizJoCo @sincpack https://twitter.com/NPR/status/1311974600142708736
In the largest study ever of transmission patterns for COVID-19, researchers in India tested more than a half-million contacts of 85,000 cases to examine how and to whom the coronavirus is spreading.
Finding: Children are spreading the virus amongst themselves and also to adults
Finding: Children are spreading the virus amongst themselves and also to adults
What's been unclear is how much kids contribute to spreading COVID-19 to the rest of the community.
"What we found in our study is that children were actually quite important."
"What we found in our study is that children were actually quite important."
"Kids were likely to get infected, particularly by young adults of the ages of 20 to 40. They were likely to transmit the disease amongst themselves. And then they also go out and infect people of all age groups, including the elderly."
"The proportion of children who are infected but don't show any symptoms is higher than adults. So they may not even be recognized as potential carriers.
Many kids are silent spreaders in the sense that they don't manifest the disease with symptoms"

"this is a study that shows that children do indeed spread the virus to other children. This will have major implications for kids returning to classrooms, to sports and to other activities where kids tend to be in close contact to each other."
Study #2 out this week showing significant role children play in spread of SARS-COV2 virus and infection spread.

The number of children infected with COVID-19 rose dramatically between April and September 2020, rising from 2.2% to 10% of all cumulative reported COVID-19 cases nationwide, according to research by the American Academy of Pediatrics and the Children’s Hospital Association.
Researchers from Princeton Env. Institute, Johns Hopkins, & UC Berkeley find children and young adults were found to be potentially much more important to transmitting the virus — especially within households — than previous studies have identified. https://www.princeton.edu/news/2020/09/30/largest-covid-19-contact-tracing-study-date-finds-children-key-spread-evidence
Epidemiological study in Israel finds reopening of schools to be major factor in reemergence of viral spread, leading to second nation wide shut down. Poor ventilation and filtration played significant role. https://www.nytimes.com/2020/08/04/world/middleeast/coronavirus-israel-schools-reopen.html
Study #3 by CDC showing impact of multiple outbreaks in Utah, where kids infected other kids & adults.
"Reports suggest that children aged ≥10 years can efficiently transmit SARS-CoV-2."

"Transmission was documented from these children to at least 12 (26%) of 46 nonfacility contacts (confirmed or probable cases). One parent was hospitalized. Transmission was observed from two of three children with confirmed, asymptomatic COVID-19."
Ex #4: This contradicts yesterday's guidance from health dept.
"In districts that opted to open for in-person learning...have seen higher rates of COVID-19 transmission, cases and quarantines as the virus runs rampant through their buildings." @JOCOHealth http://cjonline.com/news/20201002/education-commissioner-kansas-schools-must-find-better-solution-for-remainder-of-school-year

Ex #5: District officials believed that a vast majority of cases in the schools were the result of exposures outside of school & that there was minimal spread within schools themselves. But once school doors were shut, students & staff cases fell sharply. https://www.nytimes.com/2020/10/18/us/coronavirus-schools-reopening-outbreak.html
Ex #6: Continuing evidence that shows kids do get infected, can transmit to other kids and adults, and just like adults can themselves be super spreaders. https://twitter.com/yaneerbaryam/status/1318917775449034753?s=19 @theSMSD @JOCOHealth
Ex #7: Additional evidence that kids can infect other kids & adults, have same viral load as adults, and can be a super spreader.

New Meta Study: reopening schools causes R, transmission rate, to surge. When R is above 1.0, an outbreak can grow exponentially.
Transmission rises by 24% within a month of children returning to classrooms, models using data from 131 countries show. https://www.independent.co.uk/news/science/coronavirus-r-rate-school-closures-lockdown-lancet-study-b1251617.html

Ex #9: that students infect both other students as well as staff, and are driver of infection within homes. https://twitter.com/DrZoeHyde/status/1324606718580420608?s=19 @OusleyforSMSD @theSMSD @JOCOHealth @sanmiareola @EpiElizJoCo @kneanews
Responding to evidence that students infect other students and staff, state of Utah issues emergency order stopping all high school winter sports, clubs, and extracurricular activities for two weeks. @JOCOHealth @theSMSD @OusleyforSMSD @sanmiareola https://twitter.com/UtahCoronavirus/status/1325659044061720577?s=19
