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) -- Hundreds gathered outside Fire Station 21 in Pacific Beach Tuesday evening to remember a San Diego Fire-Rescue Department firefighter killed in a motorcycle crash over the weekend.Ryan Ferrara, 39, was riding on the back of the motorcycle as a passenger when it crashed into a parked vehicle. It happened July 18 at the 13000 block of Piping Rock Lane in the Lakeside area.The driver of the motorcycle was hospitalized; he has not yet been identified. Authorities say neither the driver nor Ferrara were wearing helmets.RELATED: San Diego firefighter killed in Lakeside-area motorcycle crashThe crash is still under investigation, but the San Diego County Medical Examiner's Office says alcohol or drugs may have been factors in the crash.Many who knew Ferrara were visibly distraught during Tuesday's remembrance ceremony. At sunset, the crowds moved to the boardwalk and sands. Many firefighters were there to show the family their support.Capt. Rich Marcello, who worked with Ferrara, says it's a Fire Station 21 tradition to go down to the beach and watch the sunset after every shift when possible."Every evening, we come out and watch the sunset and gather round each other and kind of hang out with each other, which is why we're here with the family today," he said.Before he was a firefighter, Ferrara was a lifeguard. In his free time, he loved to surf, according to those who knew him."Everybody loved him, great Personality. He's just the whole package," Marcello said. 1509

SAN DIEGO (KGTV) - Hawaii recently passed a ban on sunscreens containing certain chemicals deemed harmful to their coral reefs.With more than 70 miles of coastline in San Diego County, the question of whether a similar ban could affect our region has been brought to light.The chemicals in question are oxybenzone or octinoxate, both of which are found in many commonly purchased sunscreens.RELATED: What ingredients to avoid, look for in reef-safe sunscreensA study by the Haereticus Environmental Laboratory found the chemicals seep into young coral and lead to coral bleaching, which occurs when an increase in sea temperatures kills the algae that grow inside coral, turning reefs white. This eliminates other nutrients that sustain marine life.Researchers say 14,000 tons of sunscreen lotion gets into reefs around the world every year.We asked our 10News Facebook fans how they would feel about a similar ban in California. At press time, 81 percent said they would support similar legislation in our state:When asked for comment regarding a similar California ban, the Governor's Office told 10News they do not comment on any potential legislation and there is currently no bill in the works.While San Diego doesn't have a robust coral ecosystem, the region is home to scenic coastlines that draw tourists from all over the world and off-shore fishing that fisherman enjoy just the same.RELATED: Hawaii moves to ban certain sunscreens to save coral reefs"The physical block more hitting and going away, the more chemical blockers are causing a chemical reaction," Mark Vierra, a dermatologist in Rancho Bernardo, told 10News. "You think about the old surfer with the white on the nose, people didn't always love that but now they're micronized, so I have a physical block on now and it doesn't look totally white."There are no studies on how sunscreens affect San Diego's coastline, which is home more to kelp forests than coral reefs. For now, Vierra suggests picking one and sticking with it."I always want patients to pick one that they like and they'll use consistently and reapply," Vierra said. "That's probably more important than which individual one you pick." 2214

SAN DIEGO (KGTV) - Homeowners in La Mesa are being warned their houses could be at risk of a destructive pest: Formosan subterranean termites.San Diego-based company Thrasher Termite & Pest Control made the unfortunate discovery this month in a La Mesa home."Unlike native subterranean termites, the termites we observed were extremely active, didn't flee when disturbed, and the soldiers went into attack mode. They had hollowed out large areas of structural wood, always staying just beneath the exterior paint and unnoticed by the homeowner," said Garrett Thrasher.They're deemed "super-termites" due to enormous colonies up to two million strong. The pests can cause significant structural damage within six months unlike traditional dry-wood termites, which take 10-15 years to do similar damage.RELATED: Heat and humidity creating perfect conditions for bugsThe invasive species of termites was first discovered in La Mesa in 1992. Efforts to eradicate the population were thought to be successful, but pest control experts say that's no longer the case. Years after the discovery, monitoring efforts eventually stopped due to a lack of funding."They can't fly very far, but there's so many of them that they've continued to survive since the last sighting," said Thrasher.About 60 homeowners have received letters from San Diego County officials warning of potential risk.Thrasher says it's hard to say how large the problem is but he believes the pests have a strong foothold in the area.According to the University of California Agriculture and Natural Resources, the 1992 Formosan subterranean termite infestation was estimated to be about ten years old. This age corresponds to a time that a family living at the epicenter of the affected area brought wood and potted plants with them when they moved to La Mesa from Hawaii. Formosan subterranean termite is common in Hawaii; the species was misidentified for several years after its introduction in San Diego.RELATED: San Diegans report increase in mosquitoes during heat waveAs with virtually all species of termites, researchers say the hidden nature of young Formosan colonies make them especially difficult to detect and identify. Damage by young colonies is often localized and may go unnoticed for years.HOW CAN YOU TELL IF YOU HAVE FORMOSAN TERMITES?Check for what may look like paint chips around your windows or any wood area of your home. These may be hollowed-out areas created by termites.You can also check trees on your property for any obvious signs of termite; wood often appears to have been eaten away along the grain pattern.Another red flag is seeing swarmers; this is how they reproduce.WHAT CAN YOU DO IF YOU HAVE AN INFESTATION?Calling a pest control company is the first step. A professional will need to treat your home and create a chemical barrier. 2860
