Having an adequate supply of personal protective equipment could have saved the state of California hundreds of millions of dollars and stopped roughly 18,000 essential workers from getting the coronavirus, according to a new study from the University of California Berkeley.Researchers at the school looked at the cost of PPE and the early costs and infection rates of coronavirus in California. They conclude with a recommendation that the state stockpile PPE for a future pandemic.The team’s first data point is based on supply and demand; purchasing PPE when it is not high in demand, then saving it for when it's needed. According to the study, the cost of purchasing the same amount of PPE when there was not a global demand would be 17 percent of what the projected cost is now during the pandemic.“Maintaining the stockpile would be cheaper than real-time purchases even if it was not needed for another 35 years, and even if we were fortunate enough to not need the stockpile for longer than that, it would be a highly financially prudent form of insurance,” the researchers stated.Between mid-March and mid-July, roughly 250,000 healthcare workers in California filed for unemployment benefits because there was not sufficient PPE for them to go to work.For each week those healthcare workers could not report to work, it cost the state million in unemployment benefits. The researchers conclude millions could be saved by having the personal protective equipment available.Looking at rates of infection and studies from Europe showing transmission rates at hospitals, Berkeley researches believe almost 18,000 coronavirus cases among essential workers could have been prevented with an adequate supply of PPE.“If those worker cases had been avoided, an estimated 3,030 secondary cases among household members could have also been avoided, thus totaling at least 20,860 cases that could have been averted,” the study states.A separate survey conducted in June and July asked California’s skilled nursing facility staff about equipment; more than 20 percent reported still having inadequate supplies of PPE, and 80 percent said they were very or extremely concerned about workplace infection.The Berkeley study also appears to give support to California Senate Bill 275 as amended in July 2020, that “would require the state to create a PPE stockpile sufficient to protect healthcare and other essential workers for at least 90-days of a future pandemic or health emergency.” 2496

FULLERTON, Calif. (AP) — Police say a suspect has been arrested in the stabbing death of a man at the California State University, Fullerton campus.Fullerton police Lt. Jon Radus on Thursday told The Associated Press that 51-year-old Chuyen Vo was arrested Wednesday night at his home in Huntington Beach. Vo is suspected in the death of a former co-worker, 57-year-old Steven Shek Keung Chan. Police would not elaborate on the work relationship between the two men.Chan worked as the director of budget and finance and student services for university extended education but retired in 2017. He returned to the campus in January to work as a consultant.Authorities have said Chan was found stabbed numerous times inside his silver Infiniti in a campus parking lot on Monday, and they believe it was a targeted attack. 825

HENDERSONVILLE, Tenn. – As COVID-19 cases spike across the country, parents are struggling with whether or not to send their children back to school this fall. There are tools that can help make that decision though, like state-specific modeling data.Courtney Noffsinger of Hendersonville, Tennessee, is among the many parents grappling with this kind of anxiety.The mother of two has spent most of the blistering hot summer social distancing from other family members and friends. She and her husband even recently purchased an RV to go on camping trips, so they wouldn't run the risk of catching COVID-19 from crowded vacation destinations.For Noffsinger, the idea of sending her kids back to school where they’ll be surrounded by hundreds of other students and potentially exposed to the virus is daunting to say the least.“Parenting is already hard, parenting in the middle of a pandemic has been extremely difficult,” Noffsinger said as she watched her daughter scroll through TikTok.Noffsinger’s two kids haven't been to school since March and are both anxious to get back into the classroom. Her 14-year-old son Keagan is entering high school and her 11-year-old daughter Presley is entering middle school. While both children have asked their parents to return to in-person learning, Noffsinger is nervous about sending her kids back to school, especially given her daughter’s underlying asthma.“As their parents, we want to give them what they want, but we’re fearful, especially when the data keeps changing,” she said.As coronavirus cases continue to rise across the country, school districts are being faced with the reality of trying to provide education to the nation’s young people in the midst of the pandemic. While some of the country's largest districts have decided the entire fall semester will be virtual, many other districts are turning to hybrid models where students will attend school at least one or two days of school a week.COVID-19 has created a complex paradox for both parents and educators. They’re weighing the health and safety of students against the prospect of losing valuable learning and social interactions that can't be replicated online.But both parents and teachers are fearful that sending kids back into school environments will give the virus exactly want it wants, crowds of people to spread across.“Parents don’t like to hear me say it, but we will be undertaking a whole series of experiments across this country and we will have to see how those experiments turn out and be prepared to change what we’re doing to keep up with the virus,” said Doctor Williams Schaffner, who serves as a professor of preventive medicine at Vanderbilt University.As COVID-19 cases continue to spike across a large swath of the country, Schaffner says parents need to be vigilant at home when it comes to instilling proper protections like wearing a mask and washing their hands. The more normalized those behaviors are at home, he says, the more likely they’ll be emulated in the classroom. And the less likely it is that the virus will spread.“Model the importance of wearing a mask, practice social distancing. If you do that in your family already, it’ll be easier for your child to understand what’s happening in school,” he said.So, where can parents turn for guidance about whether to send their kids back to school?The Massachusetts Institute of Technology (MIT) has created the COVID-19 Projection Machine, which gives parents an interactive map to work with. As you scroll over each state, you can see current case numbers, hospitalization rates and most importantly, the positivity rate for your state. Health experts say once a state’s positivity rate crosses 5%, parents and school districts should take note.Since the virus is not under control in the United States, Schaffner says parents, students and educators who are returning to in-person learning will need to be flexible as the year progresses.“If there’s an increase in your community and an increase related to the school itself, that school system will have to figure out if there’s a trigger point there, where they call a time out and everyone stays home and the learning becomes virtual,” Schaffner said.As for Noffsinger, she has decided to let both of her children return to school on a hybrid schedule. It’s a decision she’s told them comes with a great deal of responsibility on their part as well.“We’re fearful for their health, but also understand the importance of their education,” she said. 4518

Heads (and eyes) up, skywatchers! The annual Perseid meteor shower is underway and will hit its peak this weekend.The meteor shower, so named because the meteors appear to come from the constellation Perseus, lasts for several weeks – from July 17 to Aug. 24 – but peak meteor activity will take place between about 4 p.m. ET on Sunday, Aug. 12 and 4 a.m. on Monday, Aug. 13, according to NASA.During the peak, one can expect to see as many as 60 or 70 meteors per hour.Night sky conditions should be great for meteor viewing: The peak coincides perfectly with the new moon, meaning the sky will be plenty dark and meteors will be easy to spot. Most meteor showers are best after midnight. 702

Google said Monday it is shutting down the long ailing social network Google+ for consumer use amid new scrutiny of the company for reportedly failing to publicly disclose a security bug affecting users of the service.In a blog post, the company admitted Google+ had failed to achieve "broad consumer or developer adoption" since it launched as a would-be Facebook rival in 2011. However, the announcement came moments after The Wall Street Journal reported Google had opted not to disclose a bug affecting hundreds of thousands of Google+ users at least in part to avoid additional regulatory scrutiny.Google said in the blog post that it "discovered and immediately patched" a bug in March 2018. It said the bug could have affected up to 500,000 Google+ accounts, but the company found "no evidence" that any data was actually misused."Every year, we send millions of notifications to users about privacy and security bugs and issues," a spokesperson for Google said in a statement provided to CNN Business. "Whenever user data may have been affected, we go beyond our legal requirements and apply several criteria focused on our users in determining whether to provide notice.This is a developing story.
