SAN DIEGO (KGTV) — From business closures to limits on gatherings, there’s mounting evidence that government restrictions do slow the spread of COVID-19. But which policies are the most effective?A study published this month in the journal Science aims to answer that question by examining data from 41 countries outside the U.S.The researchers examined seven kinds of COVID-19 policies in mostly European countries and compared them to case and death rates in those countries over time.The policies included limiting gatherings to 1000 people or less, to 100 people or less, and to 10 people or less; a targeted closure on high-risk businesses; a broad closure of most non-essential businesses; school and university closures; and stay-at-home orders.The authors found limiting gatherings to 10 people or less was the most effective nonpharmaceutical intervention of the seven examined, reducing the transmission rate by 42 percent.Closing schools and universities was next, cutting transmission by 38 percent. The researchers said they were not able to examine the relative importance of closing universities over grade schools because such closures were typically implemented at the same time.Next, the researchers examined the impact of two kinds of business closures. They found broad closures of most non-essential businesses were “only somewhat more effective than targeted closures” of high-risk businesses like restaurants, bars and nightclubs. Broad business closures reduced transmission by 27 percent compared to an 18 percent reduction for targeted closures.“Therefore, targeted business closures can be a promising policy option in some circumstances,” the authors wrote.The study estimates those three policies together -- closing high-risk businesses, closing schools and universities, and limiting gatherings to no more than 10 people -- are enough lower to slow the spread of the virus.In epidemiological terms, interventions are considered successful when they lower the so-called number below 1. The reproduction number, or R number, is the average number of people who become infected from one infectious person. Without interventions, the study found the R number for COVID-19 between January and May was 3.3.The study did not examine the impact of wearing masks, but other studies have found that masks can also significantly reduce the spread of COVID-19.So what about stay-at-home orders? Mandatory stay-at-home orders where people are only allowed outside for essential tasks or during certain times of the day tend to be a last resort, when there are other restrictions already in place.The researchers found mandatory stay-at-home orders cut transmission another 13 percent on top of other policies. “Issuing a stay-at-home order had a small effect when a country had already closed educational institutions, closed nonessential businesses, and banned gatherings,” the authors wrote. 2919

SAN DIEGO (KGTV) - Honda has agreed to pay million to settle allegations surrounding airbag failures.The lawsuit was brought by a collation of Attorneys General in 48 states.According to the Attorney General of New York the settlement, "Concludes a multistate investigation into Honda's alleged failure to inform regulators and consumers of issues related to the significant risk of rupture in the frontal airbag systems installed in certain model cars, which could cause metal fragments to fly into the passenger compartments of many Honda and Acura vehicles."The California Attorney General’s Office says Honda also agreed to a number of injunctive terms to protect consumers, including requirements that it include design features that protect vehicle occupants in the event of an airbag rupture and a prohibition from engaging in false or misleading advertising related to the safety of its frontal airbags."For years, Honda failed to warn consumers and regulators of the potential dangers of its airbags. That type of business practice not only violates Californians' trust but endangers lives," said Attorney General Xavier Becerra. "Every time we get into our vehicle, safety is a priority. In case any company forgets that California is ready to remind you and hold you accountable."ABC 10News reached out to Honda for a comment on the settlement but did not hear back.According to the California Attorney General’s office, the ruptures have resulted in at least 14 deaths and over 200 injuries in the United States alone."It's a win for the consumer," said Alexander Brangman.On Sept. 7, 2014, Brangman's daughter Jewel rear-ended a van in her rental car on a freeway in Los Angeles. Four vehicles were involved. Everyone walked away from the crash, except her.Brangman said the shrapnel pierced her neck. She later died.While he applauds the actions of state leaders to reach a settlement with Honda, Brangman says he's still concerned that vehicles have dangerous airbags in them."I'm an example of something tragic happening that was preventable, and it's still happening," Brangman said.According to the National Highway Traffic Safety Administration, approximately 63 million Takata airbags have been recalled because these airbags can explode when deployed, causing serious injury or even death.To check your car https://www.safercar.gov/ 2365

SAN DIEGO (KGTV) - Governor Gavin Newsom is expected to sign a bill that would create a cap on annual rental increases. The bill passed both chambers of the California legislature this week. The bill would limit rent increases to 5% per year, plus the rate of inflation.It would also implement “just cause” protections, which require landlords to give specific reasons for evictions if tenants have lived in a unit for more than a year. 444

SAN DIEGO (KGTV) – Hospital beds are filling up quickly with available capacity at zero in Southern California.ICE Nurse Peter Sidhu is overwhelmed. The Los Angeles County RN says their hospitals are on the brink of their limits.“We’re having an influx of patients like I’ve never seen before,” said Sidhu. “We’re running out of space. We’re converting any and every room into a patient room.”He feels more protected after getting the vaccine Thursday but says being short-staffed is a whole other threat. Sidhu also serves as treasurer for the UNAC/UHCP nurses union. He says hospitals have been facing systemic nursing shortages since the early 2000s.“You’ll be lucky to even get a restroom break. You’re on your feet, you’re running, patients are being intubated,” said Sidhu. “We don’t have enough staff. We didn’t have enough staff to take care of our patients before we had COVID.”California groups counties into five regions as part of the new stay-at-home order. On Thursday, the Southern California region available ICU capacity hit zero, even though availability for San Diego County is about 16%. That’s in part because other counties contribute to our region’s total. Inyo County only has two ICU beds open as of Dec. 18. Imperial County has no beds left.“You can open up empty wings, you can convert auditoriums, you can see what some places are doing which is parking structures and tents,” said Sidhu. “But, you can’t replace nurses.”While there are still some ICU beds open in San Diego, they’re filling up quickly. Scripps hospitals tells ABC 10News they’ve requested additional ventilators and respiratory therapists from the county.“We’ve constructed temporary negative pressure rooms, added surge tents at our emergency departments, and expanded COVID care to additional hospital floors,” said Scripps spokesperson Stephen Carpowich.For people who still aren’t being safe, Sidhu as this warning.“I’m looking at the kinds of patients that we have. They’re younger than I thought they would be. They’re healthier. And now they’re all suffering from COVID,” said Sidhu.The county says they’re holding off on some vital procedures like organ transplants and cancer surgeries in non-COVID patients to make more room. 2239

SAN DIEGO (KGTV) - Health experts are weighing in after a local nurse tested positive for COVID-19 more than a week after receiving the Pfizer vaccine.In a Facebook message posted on December 18, Matthew W., an ER nurse at at two different local hospitals, talked about receiving the Pfizer vaccine that day. He told ABC 10News his arm was sore for a day but he suffered no other side effects.Six days later on Christmas Eve -- after working a shift in the COVID-19 unit -- he became sick. He got the chills and later came down with muscle aches and fatigue.The day after Christmas, he went to a drive-up hospital testing site and tested positive for COVID-19."It's not unexpected at all. If you work through the numbers, this is exactly what we’d expect to happen if someone was exposed," said Dr. Christian Ramers, an infectious disease specialist with Family Health Centers of San Diego. He serves on the clinical advisory panel for the county’s vaccine rollout.He points out, it is possible Matthew was infected before receiving the vaccine, as the incubation period may be as much as two weeks. Dr. Ramers says if Matthew did contract it after the vaccine, it’s still in line with what we know."We know from the vaccine clinical trials that it’s going to take about 10 to 14 days for you to start to develop protection from the vaccine," said Dr. Ramers.Dr. Ramers says he knows of several other local cases where health care workers became infected around the time they received the vaccine. He says all the cases illustrate the fact that results aren’t immediate. Even after you start receiving some protection, it won't be full protection."That first dose we think gives you somewhere around 50%, and you need that second dose to get up to 95%," said Dr. Ramers.Dr. Ramers says Matthew’s story also shows that even with vaccines, the pandemic isn’t going to turn around instantly."You hear heath practitioners being very optimistic about it being the beginning of the end, but it’s going to be a slow roll, weeks to months as we roll out the vaccine," said Dr. Ramers.He adds this case is a good reminder of why masks, handwashing, and other COVID protocols are important, even after receiving the vaccine.Matthew says he’s feeling better since his symptoms peaked on Christmas Day but still feels fatigued. 2323
