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) -- Parents at Eastlake High School are asking the Sweetwater Union High School District board to investigate a math teacher that students accuse of making inappropriate comments. The parents say the issue started last spring when the teacher made comments about erectile dysfunction in class. Other parents say the teacher hardly teaches, forcing their kids to fall behind. Dan Huslin, a parent of an Eastlake High sophomore, said the school's principal told him last year the teacher was suspended, but this year he found out he's back in the classroom. Huslin said when he asked about why he returned, the current principal told him the district was providing the teacher counseling to help him improve. On Monday night, parents spoke at a Sweetwater district meeting and asked the board to investigate and remove the teacher. Also, parents asked the district to provide math tutoring for the students who are now behind. A district spokesperson told 10News the teacher was not suspended last year and was instead out for personal reasons, adding that they couldn't comment on whether the teacher is receiving any counseling because it is a personnel matter. The spokesperson did say the parents concerns are being addressed, but wouldn't specify how. 1288

CHULA VISTA, Calif. (KGTV) -- Health officials are working to notify people possibly exposed to tuberculosis over several months at Southwestern College, according to County News Center. The San Diego County Health and Human Services Agency says the exposure period was from August 20 to November 8, 2018. The college says it will provide no-cost testing to identified students, faculty and staff from December 3 to 14 at Southwestern College Student Health Services. Tuberculosis is transmitted from person-to-person through indoor air during prolonged contact with an infectious individual. Symptoms include persistent cough, fever, night sweats and unexplained weight loss. “The initial infection usually has no symptoms, so we recommend testing for all those exposed to assure they are not infected,” said Wilma Wooten, M.D., M.P.H., County public health officer. “For any infected individuals, early diagnosis and prompt treatment can prevent the infectious form of the disease.”For more information call Southwestern Students Health Services at 619-482-6354 or the County TB Control Program at 619-692-8621. 1122
