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) - This week Chula Vista Police shut down yet another illegal cannabis dispensary, an ongoing problem that's grown in recent years. While the city doesn't allow any cannabis sales at the moment, police believe there's roughly a dozen or more operating illegally in the city.“One of the challenges with unlicensed, illegal cannabis business is that they move and they change. The number of facilities is always changing, the location of facilities changes quite frequently," said Captain Phil Collum.Captain Collum says their most recent bust was one of the most egregious cases he's seen, from the number of cannabis products to security measures.“I was standing inside the facility and was shocked at what they had done," said Collum. "The windows were sealed shut with metal plating; the front door was actually, had a welded security grate that was locked closed, it had pretty much sealed off any emergency evacuation routes to this facility.”He says if there were a fire or sudden emergency in the building people could have been trapped. Captain Collum said they were alerted to the illegal operation by neighbor complaints. "It’s so important that community contact us and let us know where they believe an illegal cannabis for marijuana business might be located.”Chula Vista PD partnered with Chula Vista's Office of the City Attorney and the Code Enforcement Department to serve a civil abatement warrant for the illegal cannabis dispensary. “I’m not frustrated with the process, what’s frustrating quite honestly is people are taking advantage of our community.”Captain Collum urges the public to continue notifying authorities when they spot illegal businesses popping up in the city. 1731

China said Friday it will temporarily reduce tariffs on imports of American-made cars as it tries to negotiate a trade deal with the United States.Citing the meeting earlier this month between US President Donald Trump and Chinese leader Xi Jinping, the Chinese Finance Ministry said in a statement that it will remove the additional 25% tariffs on car imports from the United States for three months starting January 1. That will bring China's tariffs on American-made cars to 15%, in line with those for cars made in other countries.China also said it would suspend its 5% tariff on 67 other auto parts.China imposed the additional tariffs on US cars in July and on some auto parts in September as part of its retaliation in the trade war between the two countries.At their meeting in Argentina, Trump and Xi agreed to a temporary truce while they try to negotiate a broad trade deal over the next 90 days.In its statement Friday, the Finance Ministry described the decision to remove the tariffs as a "concrete action" aimed at helping to bring about a "mutually beneficial new Sino-US trade order."Xi pledged in April that China would cut tariffs on imported cars this year. His government delivered on that promise in July, reducing import taxes from 25% to 15%.But just days later, China imposed new additional tariffs of 25% on American-made passenger vehicles as the trade war with the United States escalated.The tariffs hurt profits of major automakers that ship cars to China from the United States. Germany's BMW and Daimler, the owner of Mercedes-Benz, have been hit particularly hard. Shares of BMW (BMWYY) and Daimler (DDAIF) both trimmed early Friday losses on the news.The stocks had spiked last week after Trump tweeted that China was going to cut auto tariffs.General Motors (GM) and some other automakers already have a large presence in China through partnerships with local manufacturers. It has become the largest and most important market for the American auto industry. Because their plants are in the country, they weren't subject to big import taxes.Yet China's tariffs have hurt exports from US auto plants. The value of US passenger car exports to China has fallen by .4 billion, or 30%, over the course of the first nine months of the year.Part of that could be because of slowing Chinese auto sales. Yet overall sales of American cars in China -— including those made in China — are down only about 1% so far this year.The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company.
