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, Calif. (KGTV)— The Chula Vista Police department is investigating a home invasion robbery that happened Saturday night on the 1600 block of Claret Cup Drive.80-year-old Don Oder believes he may have had an encounter with one of the suspects.He told 10News he was unloading the bags from his late night shopping trip Saturday and saw a man walk into his garage.“He says 'I’m thirsty. Can I have some water?' So I got him a glass of water,” Oder said. That was around 10:30 p.m. at Oder's home near Camarena Elementary School.At the time, Oder did not know that the person who asked for water could have been a suspect in a home invasion robbery that happened moments prior. “I didn’t put two and two together right away,” Oder said. Chula Vista Police said someone fired a gun at a nearby condo on Claret Cup Drive around the same time.Two people entered and robbed the residents, then ran east. No one was hurt.Looking back now, Oder believes one of suspects may have been the man hiding in his garage.“Pretty obvious that he didn’t want to be seen,” Oder said. Oder describes him as a young, built, clean-cut man.He was surprised at the man’s get-away car.“He said, I’ve called an Uber and it’s going to be here in a few minutes.”Oder stayed with him for a few minutes until the man suddenly ran.Moments later, he and his grandson called police. The next morning, Oder’s son Tim was walking toward the crime scene.Tim Oder said he found a bundle of stuff next to a car along Exploration Falls Drive.“I pulled a hat out, walked a little further, and then I started pulling some gloves, and I thought, oh my God, these are white latex gloves!” Tim Oder said. The water cup and the bundle of items are now with Chula Vista Police, being processed for evidence. The Oders said the fact that one family had two run-ins with an unusual crime in a safe neighborhood is a crazy coincidence.“It seemed so strange, you know?” Oder said. Chula Vista Police said the suspects are still at large and asked the community to be vigilant. 2154

Cigarette use among American adults is at the lowest it's been since the Centers for Disease Control and Prevention started collecting data on the issue in 1965, according to a report released Thursday."The good news is that cigarette smoking has reached unprecedented lows, which is a tremendous public health win, down to 14 percent from over 40 percent in the mid-1960s," said Brian King, senior author of the report and deputy director for research translation at the CDC's Office on Smoking and Health. About 47.4 million Americans, or 19.3%, used any tobacco product in 2017, the report says.He believes that the decline is due to proven interventions, such as smoke-free policies and rises in the price of tobacco products.As stated in the report, the data is from the National Health Interview Survey, "an annual, nationally representative, in-person survey of the noninstitutionalized U.S. civilian population." The 2017 sample included 26,742 adults and had a response rate of 53%.Researchers assessed the use of five types of tobacco products: cigarettes, cigars, pipes (including water pipes and hookahs), e-cigarettes and smokeless tobacco (such as snuff or dip)."During 2016-2017 declines occurred in current use of any tobacco product; any combustible tobacco product, [two or more] tobacco products; cigarettes; and smokeless tobacco," the report says.King added, "on balance, we still have some public health hurdles in that there is still 47 million Americans that are using some form of tobacco products, and we still have significant disparities among the groups in the country in terms of tobacco product use."So, who is still using these products, and what are they using?Beyond the 14% of Americans smoking cigarettes, 3.8% are smoking cigars, 2.8% are using e-cigarettes or vaping, 2.1% use smokeless tobacco products, and 1% are using pipes.Males (24.8%) were more likely to be smoking than females (14.2%). The highest age group for smoking was among those between 25 to 44 (22.5%); those 65 and older smoked the least (11%). Southerners and Midwesterners (20.8% and 23.5%, respectively) smoked more than those in the Northeast (15.6%) and the West (15.9%)The researchers also looked at race, education level, income level, sexuality, insurance provider and marital status to determine smoking rates.Although cigarettes are the leading cause of tobacco-related deaths and diseases in the country, according to King, he also believes other tobacco products, such as e-cigarettes, need to be considered to continue declining rates of overall tobacco product use."It's critical that we not only modernize our strategies in terms of population but also modernize our interventions to be sure that we are capturing the full diversity of tobacco products that the American public are using," King said. 2850

CHICO, Calif. (AP) — Another person killed in the deadliest wildfire in California history has been identified.The Butte County Sheriff's office said Friday it positively identified the remains of 68-year-old Judith Sipher of Paradise.That brings the total number of named dead to 81. Three people whose remains were recovered after the wildfire are tentatively identified but have not yet been named by the sheriff's office. Two of the 86 victims remain unknown.The fire in November last year destroyed nearly 15,000 homes in Paradise and surrounding towns. In the aftermath of the catastrophe, authorities used DNA testing to identify bone fragments and other remains of the victims. In some cases, it took months to positively identify the victims and notify their next of kin. 788

CHULA VISTA (KGTV) -- Laurence and Cherryl Lector's two small children were eager to show off their costumes and hit up their neighborhood for sweets. But the couple didn't want to abandon their home on Baywood Circle in Chula Vista and disappoint the several trick-or-treaters likely to stop by for confectionery.So, the couple filled a large candy bowl hoping their security camera -- fixed visibly in their porch -- would keep visitors honest.  The family then set off on their haunts.The Lectors phones were buzzing with video alerts showing little ghosts and ghouls digging through the self-serve candy bowl and respecting the Halloween honor system.Then they received a video showing an esurient group of older kids, and one small girl, emptying out the dish into their bags."I was devastated someone could just get all the candy and ruin the night [for other trick-or-treaters]," said Laurence Lector.One of the kids noticed the camera and even pointed it out to someone else in the group, but the kids continued to snatch all of the treats until every sweet was gone."We were disappointed that those that came afterward came to an empty bowl," Cherryl Castro-Lector told said.About an hour later, they received a video from their camera that warmed their hearts.The video shows a girl and boy investigating the empty bowl.  They must've known that the night wasn't over for other little trick-or-treaters. So, the group took turns emptying their own their treats into the bowl, starting with their mom."I got a little teary eyed.  Gosh, I hope my kids are like that someday," Castro-Lector said. "I would have hugged those little kids and mom if I were there."The Lectors are eager to find these children and their parents to say thanks.  "I would love to meet them and thank them for being so kind. Not just for me but everybody that followed and enjoyed Halloween, as they should," Castro-Lector said. 1969
