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 Pfizer’s COVID-19 vaccine rolls out to healthcare workers, at least four have had severe allergic reactions after getting the shot.The cases include two healthcare workers in Alaska and two in the UK. In the UK cases, both individuals carried epipens.“So these were people with a history of severe allergies and not just severe allergies like you got hives, but they had allergies where they encounter certain things in the environment and their body shuts down,” said UC San Francisco infectious disease expert Dr. Peter Chin-Hong.All four have apparently recovered.At this point, doctors aren’t sure what caused the reactions. Generally speaking, allergies when your immune system overreacts to something harmless.Pfizer’s vaccine has 10 ingredients that fit into four categories.The active ingredient is mRNA. These are temporary genetic instructions for your cells to build a small, harmless fragment of the virus’ shell to train your immune system, similar to setting up a punching bag to train a boxer.Then there are fats to stabilize and transport the mRNA, salts to maintain the pH, and sugar to prevent the solution from degrading while freezing.All the ingredients are considered standard. Dr. Chin-Hong says he was struck by what’s not in the vaccine.“They didn't have egg products or any of those kinds of things that people might be allergic to,” he said. “They didn't have live virus, which might also elicit a response.”The only ingredient with a history of allergic reactions is polyethylene glycol, or PEG, one of the fats that acts as an oily bubble for the mRNA.PEG is also in Moderna’s vaccine and it’s common; it’s found in ultrasound gel, laxatives, injectable steroids and other products.Although PEG allergies are rare, the FDA says people who are allergic to any of the 10 ingredients should not get the vaccine.However, experts say people with common allergies should not worry.“A lot of people have minor food allergies or bee-sting allergies or peanut allergies or environmental allergies,” said Dr. Christian Ramers of Family Health Centers of San Diego. “They may even carry an epi-pen because sometimes it gets severe. Those people would not be excluded from getting this vaccine.”The American College of Allergy, Asthma and Immunology issued guidance saying people with those common allergies, including to latex and medications, “are no more likely than the general public to have an allergic reaction” to the vaccine.After every shot, people who get vaccinated have to wait 15 minutes so healthcare workers can monitor them for a reaction. Should one occur, interventions like epi-pens are very effective.The FDA said people with a history of allergic reactions to vaccines or injectable drugs can still get the shot, but they should wait 30 minutes for slightly longer monitoring.The odds of having a severe allergic reaction to any vaccine is about 1 in 760,000. That means you’re more likely to be struck by lightning in a given year, which the CDC estimates is about 1 in 500,000. 3048

SAN DIEGO (KGTV) -- Chief Border Patrol Agent Douglas Harrison apologized Wednesday after a binational garden at the border was bulldozed. Harrison said on Twitter he met with Friends of Friendship Park and apologized for the “unintentional destruction of the garden.”“The original intent was to have the garden trimmed. We take full responsibility, are investigating the event, & look forward to working with FoFP on the path forward,” Harrison continued. RELATED: Woman tries to smuggle meth with 7-year-old in car, Border Patrol saysEarlier in the month, Harrison said the binational garden was being used to cover for illegal activities happening at the border. “Measures had to be taken to eliminate the vulnerability.”More specifically, Harrison said the border fence adjacent to the garden was compromised, modified and the garden was being used as a cover to hide smuggling activities.

SAN DIEGO (KGTV) – At least 10 people were arrested during demonstrations in downtown San Diego Wednesday night that were sparked by the grand jury decision in the Breonna Taylor case.ABC 10News learned there were initially two separate protests planned in the downtown area. Eventually, the two groups joined together.Protesters marched through downtown chanting and holding signs demanding justice for Taylor. The demonstration made its way to San Diego Police Department headquarters on Broadway.Shortly after 10 p.m., SDPD tweeted that there were acts of violence and vandalism and declared the protest outside headquarters “an unlawful assembly.”According to the tweet, the crowd was ordered to disperse or face arrest. In response to acts of violence & vandalism, the protest in front of the SDPD Headquarters building (1401 Broadway) has now been declared an unlawful assembly.Demonstrators are ordered to immediately disperse. If you do not do so you may be arrested. pic.twitter.com/coUlOTVZ6p— San Diego Police Department (@SanDiegoPD) September 24, 2020 ABC 10News confirmed with police that at least 10 people were taken into custody during the protest, but officials did not disclose what charges the arrestees face.Taylor, a 26-year-old emergency medical worker, was shot and killed by Louisville police officers during a botched drug raid on her home in March. The warrant used to search her home was connected to a suspect who did not live there, and no drugs were found inside.A grand jury in Louisville on Wednesday decided that no officers will face charges for Taylor's death.Prosecutors argued the two officers who fired at Taylor were justified in using force to protect themselves after they were shot at by Taylor's boyfriend.The officer who fired the fatal shot and another officer who fired his weapon at Taylor face no charges, but former Louisville Metro Police Department Detective Brett Hankison was indicted with three counts of wanton endangerment for firing shots that went through Taylor's apartment and into an adjoining unit.City News Service contributed to this report 2118

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
