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) — California public health officials said Friday that the state's ICU capacity dropped dangerously low, prompting warnings to take the latest regional stay-at-home order seriously.The Office of the Governor announced on social media that, "there is less than 10% ICU capacity remaining statewide. We are at a critical moment. Calling all Californians - stay home & wear a mask to save lives. All hands on deck with our health & emergency teams as we address the capacity crisis."The state also broke a single-day record for new COVID-19 cases with 35,468 cases on Friday, and reached a new high in hospitalizations, with 12,013 patients, and ICU cases, at 2,669, Los Angeles ABC affiliate KABC said.RELATED: San Diego hospitals lay out plans to distribute vaccines to staffFriday, the state's COVID-19 data showed California's ICU capacity at 9% and a seven-day average 8.4% positivity rate. The Southern California region, which includes San Diego County, currently sits at 6.2% ICU capacity. The figures, however, don't necessarily give a real-time picture of staffed beds available since the state adjusts the percentage based on the ratio of COVID-19 positive and non-coronavirus patients.California's regional stay-at-home orders covered 36 counties, or about 77% of the state, as of Friday.Friday, FDA officials are expected to approve Pfizer's coronavirus vaccine for distribution. According to the CDC, front line medical workers are among the first set to receive the vaccination. 1522

SAN DIEGO (KGTV) - County health officials are encouraging local women to get vaccinated for "whooping cough" amid a possible epidemic.The county says pertussis, commonly known as "whooping cough," could turn into a possible local epidemic based on historical patterns."It’s critical for pregnant women and people who come into close contact with young infants to get vaccinated," Wilma Wooten, County public health officer, said. "Newborns are very susceptible to whooping cough because they are too young to be fully vaccinated. It is vital for pregnant women to be vaccinated in the third trimester to give protection to their unborn infants."So far in 2018, there have been 56 confirmed cases of pertussis.RELATED: This app says it can help you stay flu-freeLast year, San Diego County recorded at least 1,154 cases, the highest of any county in California. Wooten said the high numbers were partially attributed to reporting methods."Pertussis activity in our region appears to higher than the rest of the state, but much of this is due to the excellent detection and reporting of this potentially deadly disease by San Diego pediatricians and family physicians," Wooten said.Pertussis is a cyclical disease that peaks every three to five years, according to health officials. San Diego's last epidemics were in 2010 and 2014, with 1,179 and 2,072, respectively.RELATED: 20 more people died from the flu in San DiegoThe county said on in five of the San Diego County cases in 2017 were in individuals under three years of age, and 52 percent were between the ages of 10 and 17.The Centers for Disease Control and Prevention recommend a vaccination schedule to combat whooping cough: 1715

SAN DIEGO (KGTV) - Charles Schwab is the latest large investment firm to offer fractional stocks as a way to get more people to invest.The move puts more high-dollar, blue chip stocks within reach for younger customers."It's a big win to consumers in general," says Steven Fox, the owner of Next Gen Financial Planning. "That's particularly helpful for younger investors because they typically tend to have smaller accounts."A recent report says that 66% of millennials say they're afraid of the stock market. Fox thinks it's because that generation watched their parents go through multiple downturns and were turned off by its volatility.But, Fox says fractional stocks, and other new ideas from large companies are enticing more people to invest. He says many firms are starting to offer perks like zero-commission trades, fractional stocks, and on-line based accounts to help people save money and invest more."It may only be 1%, but for a lot of people over a long period of time, as you account grows more and more, that 1% can mean a difference of tens or hundreds of thousands of dollars that you would have available to pull out later in life."Fox says it also helps people keep a more diverse portfolio. He says this is the start of a shift to more direct indexing, where investors will be able to use fractional stocks to create their own groups of investments, rather than buying pre-set mutual funds or indexes."You're gonna see more technology come out that makes it easy to do direct indexing and consumers are going to see more and more options here," says Fox. 1585
