Data and images gathered by Harvard University research indicate that several hospitals in Wuhan Province, China, which was the early epicenter of the coronavirus, began seeing an increase in traffic as early as last August.The Harvard researchers stressed that the data cannot be conclusively linked to the spread of coronavirus. But the study’s authors said that the research supports its hypothesis that the virus originated before being identified last December.The researchers used satellite images from hospitals in addition to search engine data to back its study. The images showed an increase in hospital traffic while search engines showed an uptick in inquiries of coronavirus-related symptoms.The research noted that there are seasonal changes in online searches for “cough,” there was also a subsequent jump in searches for “diarrhea,” which the researchers said is a more coronavirus-specific search term. The authors said both search query terms show a large increase approximately 3 weeks preceding the large spike of confirmed COVID-19 cases.“Our retrospective analysis cannot verify if increased hospital and search engine volume is related to the SARS-CoV-2 virus,” the authors wrote. SARS-CoV-2 is the strain of the novel coronavirus. "While alternative explanations such as the 2019 Military World Games in Wuhan may explain some increases in parking lot traffic, this event opened on October 18, 2019, weeks after the initial rise in Baidu search engine traffic.“Still, further research is needed to validate the emergence of SARS-CoV-2. This study adds to a growing body of work on the value of digital sources as an early indicator of a disease outbreak in the context of limited integrated electronic surveillance data.”To read the full study, click here. 1788

DEL MAR, Calif. (KGTV) - This weekend 47 teams from high schools around San Diego and other parts of the US will compete in the FIRST California Robotics Regional Championships.The event brings the teens together to test their engineering and science skills. The teams get six weeks to design and build a robot to complete a handful of tasks.But the technology isn't cheap, so many teams turn to local tech companies for donations.San Diego based tech-giant Qualcomm is the title sponsor of the competition. They also give money to individual teams. Organizers say the companies see it as a way to excite teens about careers in STEM."They look at this as their future workforce," says Regional Director David Berggren. "If we can get these kids invested in STEM fields now, they're going to be great future employees, and it's money well spent for the company."The actual dollar amounts aren't given, but some schools say companies donate thousands of dollars each year. Logos on t-shirts and team booths show companies like Apple, Qualcomm, Viasat, 3M, Solar Turbines, BAE Systems, leidos and more have made donations.In addition to the money, companies donate time, providing volunteers to mentor the teens through the design and building process. They work hands on with the teams, giving kids an up close look at careers in STEM fields."It's eye-opening, it's surreal," says Southwest High School Senior Alejandro Gendrop. "To not only have someone aid us with how we're supposed to organize our team, put it together, but also to get a view into the industry and how they work and how similar our work is to theirs, it's great."The competition in Del Mar is Friday and Saturday, and admission is free. Winners from this weekend advance to the national championship in Houston next month. For more information, go to http://casd.cafirst.org. 1853

DEL MAR, Calif. (KGTV) — The Del Mar Fairgrounds may face increased pressure to stop the Crossroads of the West gun show from selling so-called 'ghost gun' kits at its show starting later this month.The Del Mar City Council on Monday will consider passing a resolution recommending the Del Mar Fairgrounds ask the show to prohibit its vendors from selling unregulated firearm parts, components and gun-build kids. The items do not have serial numbers and can be purchased at the show without a background check or registration.The Crossroads of the West Gun Show, which begins March 14, is likely in its final year at the state-owned fairgrounds. That's because a new law banning the sale of guns and ammo on the fairgrounds takes effect Jan. 1, 2021.RELATED: Return of Del Mar gun show sparks debate"Ghost guns are an increasing problem in California," the city said in a staff report. "Law enforcement Representative estimate there are several hundred thousand ghost guns nationwide, and that nearly half of all recent crime investigations in Southern California include untraceable firearms assembled from unregulated parts and components."In a statement, gun show president Tracy Olcott said so-called ghost guns are 100 percent legal and that building them is a hobby many enthusiasts enjoy. "These are gun parts kits that an individual can purchase and, after acquiring a serial number from the California Department of Justice, begin the process of assembling the kit," Olcott said. The Southern California ATF says untraceable guns make up 30 percent of the guns it buys undercover or are seizes. Additionally, the 16-year-old suspect in last year's Saugus High School shooting used a home-made gun. In California, those who build the guns from the kits are required to register them with the State Justice Department, and can go to jail if they don't. But Rose Ann Sharp, who heads the group Never Again CA, which has fought to end the Del Mar gun show, says that's not realistic."Do you think a 16-year-old is going to register the gun? Do you think a felon is going to register a gun? Do you think someone who is suicidal who is not going to pass a background check is going to register a gun? No," she said. But Danielle Jaymes, who heads sales at Poway Weapons and Gear range, said people who want to break the law will, no matter what. "If they aren't legally allowed to buy a gun in California and they go across state lines and buy an unfinished frame and then build up themselves, they're going to do it," she said. "They're always going to find a way around the laws in order to circumvent them."A spokeswoman for the Del Mar Fairgrounds did not immediately issue a statement on the proposed ordinance. 2729

Delta is partnering with the Center for Disease Control (CDC) to become the first airline to launch a contact tracing initiative for international travelers arriving in the United States.Beginning Dec. 15, the Atlanta-based carrier will ask all customers to voluntarily provide their contact information for "contact tracing and public health follow-up efforts.""This will give the CDC access to the data in moments, dramatically decreasing the time it takes to notify affected customers via local health departments," Delta said in a press release.Each passenger will need to provide their full name, both a physical and email address, as well as two phone numbers.Once a passenger fills out the form, Delta will securely forward the information to U.S. Customs and Border Protection, who will pass it along to the CDC."This will give the CDC access to the data in moments, dramatically decreasing the time it takes to notify affected customers via local health departments," the company said.However, this program will not pertain to the carrier's quarantine-free flight trial to Italy, which Delta announced last week.Through a partnership with the Aeroporti de Roma and Hartsfield-Jackson Atlanta International Airport, Delta will have a first-of-its-kind trans-Atlantic COVID-19 testing program.Delta said that participating consumers eligible to travel would be granted an exemption from quarantine restrictions on arrival into Italy. 1448
