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) -- From Teddy Bears to cereal boxes, the TSA gave an exclusive look at the alarming items used to conceal explosives at the airport. 4.1 million travelers are expected to travel in and out of San Diego this summer, making it busier than ever. “It may seem like a pain on some travel days taking off your shoes dropping them in a bin and separating a laptop in another but it could be saving your life.”If you’ve traveled through an airport, you’re no stranger to the TSA checkpoint. “Our officers need a clear view of the electronic itself making sure circuitry, the electronics inside of it haven’t been tampered with.”It’s not just electronics, but stuffed animals are also used to disguise explosives. “Because they think that our officers would be disarmed because it’s a child item.”From coffee beans to baby formula and peanut butter, TSA has seen it all. “We’re in no way saying every passenger is bringing these types of items but it only takes one and we really need to get it right every single time.” 1036

SAN DIEGO (KGTV) -- Due to struggling ridership, the City of San Diego has been busy creating a plan to revamp its bikesharing program.On Wednesday staff will provide an update on improvements made and future plans, in response to a grand jury report in 2016.The program, DecoBike, is privately owned but works in partnership with the city.Critics of the program say it has not met the city's needs due to where stations were built.Last year a county grand jury report titled "San Diego's Bikesharing Program Needs Help," outlined ways the city and DecoBike could improve to better serve the community.One recommendation was to put more stations in beach communities, even though local business owners and residents protested them being there.Since then, the city has done the opposite, removing 14 stations from beach communities.City spokesperson Katie Keach says the city and DecoBike are concentrating on increasing the number of stations in the urban core.By doing this, they believe it will provide for a comprehensive system to increase alternative transportation options. They say it will also help the city meet its Climate Action Plan goals.Keach says they hope to have additional stations in North Park, Uptown, Golden Hill and downtown this winter.The city is conducting presentations to community planning groups this fall, seeking public input.Bicycle and climate activists want the program to succeed, saying it's critical to the city's Climate Action Plan.  1486

SAN DIEGO (KGTV) - Despite criticism, a spokesperson for the California Republican Party told ABC 10News on Tuesday that the party will continue placing unofficial ballot drop boxes around communities.They've popped up in Orange, Los Angeles, and Fresno counties, but so far none have been reported in San Diego. Several have been labeled "official", as confirmed by CA GOP spokesperson Hector Barajas. “We could've had better wording on the ballot boxes and so we changed some of the wording around already on the ballot boxes but the important thing to remember is that these ballot boxes are inside our campaign headquarters or inside of businesses or other organizations. It's not as though they're outside in front of a mailbox or outside a library or a secondhand store or another place of business,” he told ABC 10News.On Monday, California's Secretary of State and the State Attorney General sent a cease and desist to the GOP, calling the boxes illegal. Some argue that the boxes are deceptive and could lead to tampering. “These boxes are not the same as county election drop boxes that are required to meet state security standards,” said California Secretary of State Alex Padilla.Barajas told ABC 10News, “What is happening right now is the Secretary of State -- with this cease and desist -- is basically looking to engage in voter suppression [by] eliminating more options for individuals to be able to drop off their ballot.”Barajas said that "ballot harvesting" is a practice that allows a third party to collect voters' completed ballots and was legalized four years ago in a bill authored by San Diego Assemblymember Lorena Gonzalez.A tweet Tuesday from one of Gonzalez’s accounts reads, "Apparently, Republicans in our legislature think that when I wrote that a voter could designate a 'person' to turn in their ballot, they thought I meant a fraudulently labeled box. I'm terribly sorry. I will define person next time.”When asked how many boxes the GOP has placed around the state, Barajas responded, “We're not giving an exact number but we will say that we've got them statewide and with the amount of press we've gotten on this we're considering maybe even doubling or tripling our efforts.”The San Diego County Registrar of Voters reports it has already received 175,000 completed ballots. A spokesperson said Tuesday that any reports of unofficial ballot boxes would be referred to the Secretary of State. 2440
