Children and the elderly may be good at spreading the coronavirus among their age groups, and young adults may be the primary source of community spread, or “super spreading,” according to a new study.The study, published Wednesday, involved the coronavirus testing results of a large contract tracing effort in two states in India. Researchers had results from more than half a million people from Tamil Nadu and Andhra Pradesh regions traced after more than 80,000 primary, or index, positive cases.They found that only 8 percent of index cases accounted for 60 percent of new infections. And that about 70 percent of infected people did not infect any of their contacts."That's a hugely disproportionate effect. Superspreading has been suspected, but not really documented,” study leader Ramanan Laxminarayan of the Center for Disease Dynamics, Economics and Policy in New Delhi, and also of Princeton University, told CNN.“The greatest proportion of test-positive contacts within most age groups were exposed to index cases ages 20-44 years,” researchers found.While that age group resulted in the highest rate of secondary cases, children under 15 also had high rates of secondary spread among their own age group.During the time period researchers looked at, roughly March through August, schools were closed and there were still high rates of coronavirus recorded among children."While the role of children in transmission has been debated, we identify high prevalence of infection among children who were contacts of cases around their own age," the team wrote in their report, published in the journal Science.The data was collected thanks to rigorous surveillance and contact tracing measures.“Procedures include syndromic surveillance and (COVID-19) testing for all individuals seeking care for severe acute respiratory illness or influenza-like illness at healthcare facilities; delineation of 5km “containment zones” surrounding cases for daily house-to-house surveillance to identify individuals with symptoms; and daily follow-up of all contacts of laboratory-confirmed or suspect COVID-19 cases, with the aim of testing these individuals 5-14 days after their contact with a primary case, irrespective of symptoms, to identify onward transmission,” the study lays out. 2292

CHULA VISTA (KGTV) --  Eastlake's Design District shopping complex, which once boasted a vibrant family and adult nightlife destination for the sprawling east Chula Vista communities, lost yet another marquee tenant.Good bye, Tavern+Bowl Eastlake.The 11-year-old bowling alley and sports lounge, located at 871 Showroom Place off Otay Lakes Road, locked its doors unexpectedly Monday night.  The 16,000-square-foot establishment nestled within a modern strip mall adorned with water features, rich landscaping, and winding sidewalks was a popular spot for locals.Tavern and Bowl is one of four recent closures at the Design District: restaurant Filippi's Pizza Grotto, arcade and laser tag center Lazer Journey, and indoor go-kart track Eastlake Speed Circuit.READ:?Anonymous tip led to Filippi's inspectionIt's unclear if staff or management were aware of the bowling alley's plans to shut down.  Robyn Spencer, a sales director at the San Diego location, would only say that the tavern "has permanently closed."What is clear is that at least one regular was left in the dark.Emeka Enunwa, an Eastlake resident and manager at Work Skills, is upset that the bowling alley is gone.  He says he often brings a group of adults with disabilities to Tavern and Bowl to learn life skills by working light "volunteer-like" duties, such as cleaning and performing tasks.He says his group was there two days ago but nobody told him that would be their last shift. His group took pride working at the facility and that the news of the closure may be devastating to some. Enunwa also worried about what's happening in Eastlake that's forcing all these businesses to shut down. READ: 'Ghost Town?'?Vacant storefronts reflect mall struggles at Chula Vista's Otay Ranch Town Center"I live in the neighborhood and have seen stores close in this shopping complex," he said. "I'm beginning to feel bad as a business owner; no notice ... throwing employees out of work," he said."I'm feeling for the city...they're losing jobs, they're losing money," he said.Enunwa is working quickly to find another business partner but says it's hard "because not everybody wants to accept people with disabilities."The District at Eastlake property management group could not be reached immediately Wednesday for comment.10News' Laura Acevedo contributed to this report. 2492
