SAN DIEGO (KGTV) — As thousands of migrants part of a caravan from Honduras make their way north to the United States, the Department of Defense has updated how many troops may be sent to the border.Wednesday, the DOD reveal a list of potential stations where troops could be deployed along the U.S. southern border.This, as the group of migrants continue their journey north through Mexico, though still some time away from reaching their destination of Tijuana at press time.RELATED: 493

SAN DIEGO (KGTV) — As temperatures warm up, there is some early research suggesting air conditioning units could increase the risk of spreading COVID-19.One team of researchers swabbed several kinds of air conditioning units and found traces of the virus on one out of every four samples.One of the authors, University of Oregon professor Dr. Kevin Van Den Wymelenberg, said the research “does give us some pause.”Air conditioning units bring in little outside air, particularly when temperatures are very hot, posing a risk that viral particles could be recirculated into rooms, Van Den Wymelenberg said.However, just because the study found traces of the virus in A/C units, it doesn’t prove people can actually get sick from the contaminated air because it’s not yet clear how many viral particles it takes to infect someone, he noted.“Nobody knows what that minimum threshold is so we need to take as many precautions as possible,” he said.Dr. Edward Nardell, a professor in the Departments of Environmental Health and Immunology and Infectious Diseases at the Harvard T.H. Chan School of Public Health, said air conditioning units can generate air currents that can carry large particles farther, similar to what researchers found contributed to the spread of the novel coronavirus disease in an air-conditioned restaurant in Guangzhou, China."You are not socially distanced as much, but you're re-breathing the same air that someone else just exhaled," Nardell said. "We call it rebreathed air fraction, and if someone is infectious, often asymptomatic, you're going to be rebreathing their small particles."This week, a group of 239 scientists from 32 countries asked the World Health Organization to update its COVID-19 guidance to reflect that the virus is airborne.On Thursday, the WHO released updated guidance acknowledging that airborne transmission can’t be ruled out, but stopped short of confirming that the virus spreads through the air.Instead, the WHO said the virus primarily spreads through droplet transmission, where larger particles come out of an infected person’s mouth, then fall quickly to the ground or onto surfaces. In airborne transmission, the particles stay floating for a long time.“I think they’re underweighting the importance of this airborne route based on the best available information,” said UC Berkeley Professor Emeritus William Nazaroff, one of the signatories of the letter to the WHO.He said in a poorly ventilated room, particles might linger for 30 minutes to an hour.Scientists say one of the best ways to protect yourself is to open windows, to increase the circulation of fresh air.Scientists say upgraded air filters in AC units and standalone air purifiers could also help.Germicidal lamps may also be effective, Nardell said. The technology is almost 100 years old, and has been proven effective in protecting against tuberculosis infection.The lamps, which shine ultraviolet light, are set up to shine horizontally, high up in the room to kill floating pathogens.Nardell said the technology can be deployed cheaply and easily in a number of settings.Additional reporting by Lauren Rozyla at WFTS 3159

SAN DIEGO (KGTV) - Civil rights activists called for change Monday following the publication of a cartoon in the San Diego Union Tribune the group described as an “insulting image”. Rev. Shane Harris, president of the People’s Alliance for Justice, and other San Diego leaders held a news conference after a meeting with UT publisher Jeff Light.San Diego Union Tribune cartoonist Steve Breen created a picture of authors James Baldwin and Toni Morrison, and actor Jussie Smollett, with the title “Famous African American Story Tellers," according to Harris' email. The image was published Friday, Harris said."It was egregious to us all," Harris said at his news conference.Smollett is accused of falsely reporting being attacked by two masked men in Chicago. He reportedly told police his attackers yelled racial and anti-gay slurs and referenced President Donald Trump's campaign slogan, according to the Associated Press.Harris demanded last week that Smollett be fired from his role in the show, "Empire."Monday, Harris said Breen apologized for the cartoon. Light also agreed to profile African-American leaders and initiatives in San Diego, Harris said. 1167

SAN DIEGO (KGTV) - As schools reopen with distance learning, a local nonprofit is working to bridge the digital divide during a critical time.Tammy Hershfield co-founded Computers 2 San Diego Kids 17 years ago, providing refurbished computers to low-income children. She says the local digital divide remains a big one."One in four children in San Diego don't have computer in their home, and 50 percent of those are low income families," said Hershfield.The digital divide is now even more concerning because of COVID-19, as students begin the school year with distance learning."These kids were already at a disadvantage. They were having to do their learning just in the classroom. Not they don't even have that, so we need to get them these computers," said Hershfield.Since the pandemic started, the nonprofit has refurbished and distributed nearly 18,000 computers to local kids. Dozens of volunteers and staff are working on the computers every day."We hired 14 additional staff. We're open six days a week, working 10 hours a day to get things done," said Hershfield.Families receiving the computers pick up the computers at the nonprofit's warehouse in the Miramar area. Hershfield remembers one family, a furloughed single mother of 4 with a 17-year-old daughter applying for college and loans on a phone. That family received two computers."Mom cried, and I cried. The digital disparity is real, and COVID-19 has put a on shining light on it. We can band together and help the people that need the help," said Hershfield.Hershfield says they have about 6,000 computers being worked on and need more donated computers.The nonprofit has partnered with Cox Communications to include free internet access for up to four months. 1742

SAN DIEGO (KGTV) — County health officials say with the summer months well underway, they've seen an uptick in the number of children that have needed to be rescued from private pools after nearly drowning.Officials say there have been 49 rescues in private pools, beaches, and bays from March through July, compared to 37 in the same period in 2019 and 33 in 2018. Nearly all of those rescued this year have needed to be taken to the hospital for treatment.Of those 49 that occurred this year, 28 were in pools and 14 were in the ocean, lakes, or bays. The rest did not report a specific body of water. Many public pools have been closed since March due to the pandemic."Parents and guardians must take the necessary precautions to keep these incidents from happening," said Wilma Wooten, county public health officer, said. "Children who swim in pools at home are at higher risk of drowning, especially as parents struggle to supervise their children while continuing to work at home through the summer months because of the novel coronavirus."The county says it's important to teach children to swim, never leave a child unsupervised in or near water, avoid alcohol if you're swimming, and learn CPR.At home, the county recommends installing a fence around the pool and hot tub, installing pool alarms, and keeping an eye on drains and pool toys that could be a tripping hazard. 1389
