A new report from the CDC and Rhode Island shows COVID-19 rates below one percent in childcare facilities with young children this summer. They also found a low rate of secondary transmission among these facilities, with 15 percent of coronavirus cases resulting in transmission to at least one other person.“The critical thing here is to build the confidence of teachers, the confidence of parents,” said Dr. Robert Redfield, Director of the Centers for Disease Control and Prevention. “This study provides data, that when things are done with vigilance in partnership with the public health community, you can, in fact, in a complex situation like child care ... you can reopen child care" and have low rates of secondary transmission. The study tracked coronavirus cases at childcare facilities in Rhode Island this summer. On June 1, the state was seeing a decline in coronavirus cases and hospitalizations, and allowed childcare programs to re-open after a 3-month closure.In order to reopen, the facility had to submit a plan to the state for approval that included reduced enrollment, a cohort of no more than 20 people including kids and staff, universal use of masks for adults, and daily symptom screening of adults and kids.Roughly 75 percent of licensed center and home-based childcare facilities were approved to reopen, caring for 18,945 children.Between June 1 and July 31, there were 101 possible child care-associated COVID-19 cases identified at the facility level; among those, 49 were excluded because they had a negative COVID-19 test.Of the remaining 52 confirmed and probable cases, 30 were children; that is roughly .16 percent of the 18,945 children in childcare in Rhode Island this summer. There were 20 teachers and 2 parents who are among the confirmed or probable cases.Cases were confirmed an average of two days after specimen collection.Contact tracing led to the quarantine of 687 children and 166 staff members; that’s roughly 3.6 percent of the total children in Rhode Island care facilities this summer being impacted by quarantine efforts.The cases happened at 29 of the 666 childcare facilities, in 20 of the facilities, there was a single coronavirus case and no transmission. Five of the 29 programs, 15 percent, had two to five cases.The remaining four coronavirus cases may or may not have had secondary transmission. Health officials state those facilities were breaking protocol by moving members of a cohort around to other classrooms, delayed reporting of symptoms, etc. that made it difficult to track.The CDC warns these results were only possible because of decreasing COVID-19 rates in the state, and the community effort to slow the spread of coronavirus. This includes wearing masks and practicing social distancing when around other people.“I understand masks can be uncomfortable to wear and hard to remember to bring when you go out,” Dr. Redfield said. “Schools are not islands in and of themselves, they are connected to the communities around them.”The study says maintaining stable staffing was one of the most difficult things; needing to cover teacher breaks, vacations, etc. while still maintaining the smaller cohort sizes.They recommend additional funding to continue with the smaller class sizes. 3271

A massive scam related to COVID-19 that targeted millions of Office 365 users in 62 countries was stopped by Microsoft's digital crimes unit.The department is almost like a police department. There's even an evidence room. It's an office that is only known to the people whose job it is to investigate attacks on Microsoft customers. They're a small group, but they're mighty.Tom Burt, the Corporate Vice President for Customer Security and Trust, said the team is comprised of "lawyers, forensic investigators data analysts, business people."Burt is in charge of the cybersecurity team that goes after cybercriminals. Their job is to find, intercept and then help law enforcement stop the scam artists in their tracks."(We're) looking for things that we shouldn't be seeing in the data relevant to how Office 365 was being used by our costumers," Burt said. "When we see that we can dive deeper, look at the metadata and look at the information that's streaming through our Office 365 global network — to try to find indicators of people doing bad things."The team often uses social media to alert people to the hacks they're seeing.Cybercriminals often target people's fears and anxiety. So, these days, the coronavirus pandemic is a good hook.One of the recent lures was a "cure for coronavirus" or "COVID-19 safety tips" from the Red Cross. The hackers were hoping Officer 365 users would take the bait and click."They're able to get control of users' Office 365 accounts," Burt said. "They can then see what's going on in that account. They can act as if they're you — they can send email in your name and look to find things in your email account like passwords and other information."Burt says the hackers are good. They do research and figure out how companies are structured and who does what. They'll look at social sites and figure out exactly who to target.Some of the scams people were getting involved co-workers asking others to transfer money to an account."They're sophisticated criminals," Burt said. 'They do this work to make sure the requests look legitimate so they can be successful in stealing money."Burt says there's an easy way to prevent phishing attacks."The number one thing by far is to utilize two factor authentication on all of your accounts," he said. "If you're a business,s make sure you're doing that for your business email if you're an individual, make sure you're doing it for your individual email and financial accounts."Burt is referencing the separate codes a user gets when logging on to a website. The site will give a prompt so they can prove that they are.The cybersecurity team says two-fact authentication will eliminate 98-99 percent of attacks.The challenge has always been to find the cybercriminals. So, this time around, the digital unit went around them."We're saying, let's stop them in a different way," Burt said. "Let's take the internet tools that they're using to conduct their crime, and let's go legally take those tools away from them."Court documents from the civil case filed in Federal Court say that Microsoft has the authority to take away the tools the hackers need to conduct their scams."Basically, websites, locations on the internet from which they can conduct their fraudulent activities — whether it's launching their efforts or the place where they want you to ultimately go — we go with the court order to those registrars and transfer those domains to Microsoft control," Burt said.Doing that strips hackers' access and gives Microsoft the ability to block them."We took down the criminal infrastructure that was being used to defraud people in 62 countries," Burt said. "We're going to keep doing that work. We're committed. Its fun, it's fascinating and, most importantly, it protects our customers." 3791

A routine trip to Walmart turned into a nightmare for a Maryland woman, but now she is using her negative experience to help others. Cynthia Morales and her boyfriend Linwood Boyd, who are both blind, were at the self-checkout lane at the Walmart in Owings Mills, Maryland in late July 2017 when they asked an employee for help. While the self-serve kiosks do issue some spoken prompts, it was still a challenge for Morales and Boyd to check out. A Walmart employee helped the pair finish their transaction, but unbeknownst to Morales and Boyd, they requested in cashback, which the employee pocketed. Because no audio prompt gave them a total of their transaction, the couple had no idea this happened until the machine told them to take the cash. Unable to check their receipt, the couple asked someone outside of the store to read them it and discovered they had been charged the extra . The money was returned, but Morales and Boyd decided to shop at another nearby Walmart from then on. Because of their experience at the Walmart, they are teaming up with Melissa Sheeder — another blind Marylander — the National Federation of the Blind (NFB) and the National Federation of the Blind Maryland to sue Walmart under the Americans with Disabilities Act. “What happened to Cindy Morales is an extreme example of what can occur when companies like Walmart deploy inaccessible self-checkout or point-of-sale technology,” said Mark Riccobono, President of the National Federation of the Blind. “The real problem is that Walmart has decided to treat blind customers differently from sighted customers. Walmart’s refusal to deploy readily available technology to give blind shoppers the same choice sighted shoppers have — whether to check ourselves out or visit a cashier —makes us second-class customers. That is unlawful and unacceptable.”The lawsuit is asking for the Maryland federal district court to order Walmart to make its self-service checkout kiosks fully accessible to blind shoppers. The NFB says they have offered to work with Walmart to make their kiosks accessible but they declined the offer. Walmart officials released the following statement regarding the lawsuit: 2276

A new study out of a pediatric medical center in Chicago suggests that young children do not only spread COVID-19 more efficiently than adults, but they could be major drivers in the pandemic as schools start to reopen.The report was published at the end of July and examined concentrations of COVID-19 in the nasopharynx, or the upper region of the throat that connects nasal passages. According to the results, children ages 5 and younger who develop mild to moderate symptoms have 10 to 100 times as much COVID-19 in their nasopharynx as adults.“This is a very complex issue involving not just the virus, but everything else,” said Dr. Kwang Sik Kim, director of pediatric infectious disease at Johns Hopkins University Hospital. "We don’t have any real data to indicate to schools what they should do, what is the best recipe they need to follow.”The study raised concerns about the erratic behavior of children and how it could play a factor in the virus’ spread, reading, "Behavioral habits of young children and close quarters in school and daycare settings raise concern for SARS-CoV-2 amplification in this population as public health restrictions are eased. In addition to public health implications, this population will be important for targeting immunization efforts as SARS-CoV-2 vaccines become available.”“Don’t, under any circumstance, even think about opening that school for in-class instruction until you’ve got the virus under control,” said Lily Eskelsen Garcia, president of the National Education Association.Eskelsen Garcia teaches 39 6th-graders in Salt Lake City and says unless the infection rate of a community is below 5 percent, as outlined by the CDC and WHO, school districts should not even consider opening for in-person instruction.Currently, the infection rate in the United States is 7.8 percent."If you open a school before you get the infection rate under control, you will turn that school into the community’s super-spreader,” said Eskelsen Garcia.“Make a decision for today based on the information available today, and then act differently when you have data tomorrow. I think that’s the right approach,” said Dr. Kim. 2170
