(Press-News.org) Parents who send their children to child care can breathe a little easier – research published in JAMA Network Open from experts at Michigan Medicine, the University of Pittsburgh School of Medicine, and UPMC Children’s Hospital of Pittsburgh shows that children in daycare were not significant spreaders of COVID-19.
The study found that transmission rates of SARS-CoV-2 within child care centers was only about 2% to 3%, suggesting that children and caregivers were not spreading COVID at significant rates to others in the centers.
The study also found low rates of infection among households that had kids attending child care centers, as only 17% of household infections resulted from children who caught COVID at their centers.
Overall, the study found that only 1 in 20 symptomatic children attending child care centers tested positive for the virus.
In contrast, once someone in a household tested positive for the coronavirus, transmission to other household members was high, at 50% for children and 67% for adults.
Young children frequently contracted COVID-19 from individuals outside their child care center.
Additional safety measures
Despite the low rates of transmission in child care centers, experts still highly recommend that families get themselves and their children vaccinated against COVID-19, as additional research shows that vaccines are a safe and effective way of preventing against serious infection.
“We strongly recommend the COVID-19 vaccine for young children to disrupt the high rates of transmission that we saw occur in households that can lead to missed work and school,” said Andrew Hashikawa, M.D., clinical professor of emergency medicine.
The Centers for Disease Control and Prevention currently advises that kids with congestion, runny noses or other respiratory symptoms get tested for COVID and stay home if positive.
The findings suggest that these recommendations could be revised to align with those of other serious respiratory viruses, like influenza and respiratory syncytial virus, commonly known as RSV.
"While it's crucial to remain vigilant in our efforts to manage the spread of SARS-CoV-2, it seems that prioritizing testing and extended exclusion periods for children in child care centers may not be the most practical approach, as it can place undue financial burden on families from frequent testing, result in missed work, and hinder children's critical access to quality care and education," said Hashikawa.
This study was supported by Merck Investigator Studies Program grant 60418, the Henry L. Hillman Foundation and Flu Lab.

Next generation semiconductors: Diamond device shows highest breakdown voltage
2023-11-27
To reach the world’s goal of carbon neutrality by 2050, there must be a fundamental change in electronic materials to create a more reliable and resilient electricity grid. A diamond might be a girl’s best friend, but it might also be the solution needed to sustain the electrification of society needed to reach carbon neutrality in the next 30 years. Researchers at the University of Illinois Urbana-Champaign have developed a semiconductor device made using diamond, that has the highest breakdown voltage and lowest leakage current compared to previously reported diamond devices. Such a device will enable more efficient technologies needed as the world transitions to renewable energies.

Review article shows key role of Brazil in research on sugarcane for bioenergy
2023-11-27
Publications on sugarcane have increased exponentially since 2006 worldwide, and Brazil has had more articles published on the topic than any other country in the period, according to a review in BioEnergy Research.
The number of articles on the subject averaged about five per year between 1999 and 2006 but had reached 327 by 2021. Brazil has twice as many articles on sugarcane as the United States, which ranks first in the world for scientific publications in general. Brazil is also ahead of Australia, China and India, which are also major sugarcane growers.
According to the authors of the review, who are affiliated with the Laboratory of Plant Physiological Ecology (LAFIECO) ...
Cellular postal service delivers messages from non-human cells, too
2023-11-27
Messenger bubbles produced by human cells can pick up bacterial products and deliver them to other cells, University of Connecticut researchers report in the Nov. 16 issue of Nature Cell Biology. The discovery may explain a key mechanism by which bacteria, whether friendly or infectious, affect our health.
Extra-cellular vesicles (EVs) are like a postal service for our cells. Cells produce the EVs, tiny bubbles with a water-resistant shell made of fatty substances called lipids, and send them into the bloodstream. When another cell comes across an EV, it takes it inside itself ...
Orbital-angular-momentum-encoded diffractive networks for object classification tasks
2023-11-27
Deep learning has revolutionized the way we perceive and utilize data. However, as datasets grow and computational demands increase, we need more efficient ways to handle, store, and process data. In this regard, optical computing is seen as the next frontier of computing technology. Rather than using electronic signals, optical computing relies on the properties of light waves, such as wavelength and polarization, to store and process data.
Diffractive deep neural networks (D2NN) utilize various properties of light waves to perform tasks like image and object recognition. Such networks consist of two-dimensional pixel arrays as diffractive layers. Each pixel serves as an adjustable ...
