A new study out of a pediatric medical center in Chicago suggests that young children do not only spread COVID-19 more efficiently than adults, but they could be major drivers in the pandemic as schools start to reopen.The report was published at the end of July and examined concentrations of COVID-19 in the nasopharynx, or the upper region of the throat that connects nasal passages. According to the results, children ages 5 and younger who develop mild to moderate symptoms have 10 to 100 times as much COVID-19 in their nasopharynx as adults.“This is a very complex issue involving not just the virus, but everything else,” said Dr. Kwang Sik Kim, director of pediatric infectious disease at Johns Hopkins University Hospital. "We don’t have any real data to indicate to schools what they should do, what is the best recipe they need to follow.”The study raised concerns about the erratic behavior of children and how it could play a factor in the virus’ spread, reading, "Behavioral habits of young children and close quarters in school and daycare settings raise concern for SARS-CoV-2 amplification in this population as public health restrictions are eased. In addition to public health implications, this population will be important for targeting immunization efforts as SARS-CoV-2 vaccines become available.”“Don’t, under any circumstance, even think about opening that school for in-class instruction until you’ve got the virus under control,” said Lily Eskelsen Garcia, president of the National Education Association.Eskelsen Garcia teaches 39 6th-graders in Salt Lake City and says unless the infection rate of a community is below 5 percent, as outlined by the CDC and WHO, school districts should not even consider opening for in-person instruction.Currently, the infection rate in the United States is 7.8 percent."If you open a school before you get the infection rate under control, you will turn that school into the community’s super-spreader,” said Eskelsen Garcia.“Make a decision for today based on the information available today, and then act differently when you have data tomorrow. I think that’s the right approach,” said Dr. Kim. 2170

A recently published study looks at the potential of asymptomatic spread at grocery stores and the psychological distress of these essential workers.Researchers looked at a grocery store in the Boston area in May. They found 20 percent of the 104 employees tested positive for the coronavirus. This rate was significantly higher than the infection rate in the surrounding community, which was only reporting a positive rate of around 1 percent at the time.More than 75 percent of those who tested positive reported having no symptoms.Those employees who interacted with customers were five times as likely to test positive for COVID-19 compared to employees in other positions."We were definitely surprised to see that there were that many people that were asymptomatic," Dr. Justin Yang, an assistant professor at Boston University School of Medicine and a researcher at Harvard School of Public Health who worked on the study told CNN. "This is definitely very alarming as it means that retail grocery store employees are exposed to customers and sort of serve as a middleman for the virus - like a super spreader almost."The study also looked at feelings of anxiety and depression among the grocery store employees.About 24 percent of all employees reported feeling at least mild anxiety. The data suggests employees who were able to remain socially distant while at work had a lower rate of anxiety; 76 percent of those who reported having no anxiety were able to keep spacing while at work.Whereas 46 percent of those who did report having anxiety were unable to stay socially distant from coworkers or customers while on the job.About 8 percent of employees screened positive for at least mild depression symptoms on a self-reported questionnaire. Those who could not practice social distancing at work and commuted by public transportation were more likely to screen positive for depression.As a conclusion, the team of researchers hopes their findings are a call to action for providing comprehensive employee assistance services to help essential workers in all industries “cope with the psychological distress during the COVID-19 pandemic.”The study was published in the Journal of Occupational and Environmental Medicine. 2241
