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) - As San Diego families struggle to make ends meet, new numbers from a Bankrate.com survey show more and more people are turning to "side jobs" to help their bottom line.Different from a part-time job, like a few shifts at a fast food restaurant or office, a side-job is often web-based and allows people to make their schedule and feel self-employed."It's kind of the only job I can do without having to turn around and hand most of my paycheck to childcare," said Cathy Murphy. She teaches English to kids in China, through a website called VIPKids."It would be really tight financially if we didn't have this," Murphy added. "We could make the bills, but there isn't money for a vacation or Legoland for the kids' birthday or going out to eat and kind of the fun things that you want to do."According to Bankrate, 37% of Americans now work a side job. From that, they make an average of ,000 per year. The most popular ones include home repair (12%), online sales (7%), crafts (7%) and child care (6%). 1032

SAN DIEGO (KGTV) -- At least one person died in a Bay Park crash as rain soaked the roads in San Diego County Sunday morning. According to California Highway Patrol, the crash happened just before 6 a.m. Sunday on northbound Interstate 5 just before Clairemont Drive. CHP reports that the vehicle was traveling at high speeds just before the crash. At least three vehicles were involved in the crash. According to CHP, the driver of a pickup truck crashed into the center divide before being struck by two other vehicles. The driver of the truck was standing outside his vehicle when he was hit and killed by one of the vehicles. The driver was 48-year-old Joseph Vito Berardino, according to the medical examiner. At this time, it’s unclear how many more people may have been injured. 794

SAN DIEGO (KGTV) -- As many San Diego business owners fold due to coronavirus pandemic pressures, a few brave entrepreneurs are launching their businesses now, including a Pacific Beach couple that turned their passion for plants into a "blooming" business.It was the sign of the times for boxing instructor Cody Warden -- COVID-19 made him jobless."I was laid off during that time," Warden said. "It was not legal for me to teach boxing."His girlfriend, Tammy Nguyen, a social media content manager, was also now working out of their Pacific Beach home. But when the couple looked around, all they saw was joy."We were getting all these houseplants in our house, and it was filling this void if you will," Warden said. "It brought us companionship in a time when it was really difficult to see your friends or family."So they took a leap of faith last month, and decided to turn their passion into a business. They launched IvyMay & Co., an online houseplant curating company that offers tips and free, contact-less delivery anywhere in San Diego County."Plants are a form of therapy for people who might be depressed during this time, and being able to take care of these plants and seeing them grow gave a lot of people happiness," Nguyen said.Science backs this up. A 2015 study published in the Journal of Physiological Anthropology looked at the psychological responses of young adults to a computer task, versus an indoor plant-related task. Researchers found that people who interacted with plants had significantly lower blood pressure, as well as physiological and psychological stress.Although Warden and Nguyen cannot see their customer's smiles underneath the masks, they can hear it in their voices when they deliver. They say it reassures them that starting a business that brings joy during the pandemic was the right thing to do."If I could keep a house plant alive, you can too!" Warden laughed. "There's no such thing as a green thumb. Basic things, learn how to read your plant, and listen to what it's telling you."As the business grows, Warden and Nguyen hope to partner with local artists who can create unique pots for their plants. 2164

SAN DIEGO (KGTV) - Could you feed yourself on about per day? The San Diego Hunger Coalition is encouraging San Diegans to take part in the annual CalFresh Challenge to raise awareness about food insecurity. CalFresh public assistance allots .07 daily in food benefits, according to SDHC. The system, known nationally as SNAP, helps those in need but it is insufficient for helping people meet basic needs, SDHC says. During the CalFresh Challenge, participants must spend no more than .35 for five days on all meals, drinks, and snacks. During the week, participants must not accept free food. San Diego Hunger Coalition wants participants to post about the experience on social media with the hashtag #CalFreshChallenge. Participants are also asked to donate to SDHC. 784
