TAMPA, Fla. — Air conditioning units may be contributing to the spread of COVID-19, especially in the southern part of the United States, according to a Harvard epidemiologist.Dr. Edward Nardell is a professor in the Departments of Environmental Health and Immunology and Infectious Diseases at the Harvard T.H. Chan School of Public Health. He's done in-depth research on how air conditioning units contribute to the spread of airborne infections.Nardell said air conditioning can help airborne viruses spread in three ways.First, people go inside to cool down, when you are much safer outdoors, Nardell said. Now, we're seeing more people indoors because of the high heat and humidity, specifically in the southern states like Florida.The second problem is that air conditioning brings in very little outside air, according to Nardell. While this isn't a major problem inside your own home, it can be especially problematic in corporate settings."It just isn't economically possible to bring in outside air, recirculate it and dehumidify it," he said.Lastly, he said when people are indoors, you're often not spaced out safely as you would be outdoors."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."Nardell also said air conditioning units can generate air currents that can carry large particles even further, similar to what researchers found contributed to the spread of the novel coronavirus disease in an air-conditioned restaurant in Guangzhou, China, involving three family clusters.On the Department of Homeland Security's website, this tool can be used to estimate how long the virus would be expected to remain stable while airborne.Now, the Centers for Disease Control and Prevention is recommending restaurants increasing the distance between tables and improving ventilation.The use of germicidal lamps, a technology that Nardell said is almost 100 years old, has been proven effective in protecting against tuberculosis infection and is already in use in some settings to fight COVID-19.The lamps are set up to shine horizontally, high in the room where sterilization is needed. Air currents, stirred in part by warmth from human bodies, circulate up to the ceiling, where the ultraviolet light kills floating pathogens, and then back down again.This technology, Nardell said, is not only proven, but it can also be deployed cheaply and easily in a number of settings as society reopens.This story was originally published by Lauren Rozyla at WFTS. 2691

SUNSET CLIFFS, Calif., (KGTV) - There are mounting concerns about the stability of the some of the bluffs at Sunset Cliffs. The City of San Diego was tipped off about the cliff collapse near Hill Street last week. City crews surveyed the collapse then cordoned it off with yellow caution tape to discourage people from getting to close to the section in question. The city says the collapses are likely from rain. “There is a big crack there right up against the edge where it looks like that’s the next piece that’s going to fall,” said photographer Jim Grant, “it’s a good thing that somebody came in and put some protection up.” Grant spends nearly everyday photographing the cliffs and says he has seen his fair share of people getting too close. “They don’t realize that one slip and when you fall 60 or 70 feet, it leaves a permanent mark that’s for sure,” added Grant. Officials urge people to avoid the section that has collapsed and to always use caution when traversing through Sunset Cliffs. The city says it will have its engineers evaluate the section after this weekend’s weather before determining what steps to take next. 1145

TAMPA BAY, Fla. — According to the Centers for Disease Control and Prevention (CDC), 107 people from 21 states, including Florida, have reported contracting measles between January 1 to July 14, 2018.Measles is a virus that is easily spread by air droplets when infected persons breathe, cough, or sneeze. The first symptoms are a high fever that may spike to 105°F, cough, runny nose and red, watery eyes. These symptoms are followed by a blotchy rash that spreads from the head to the feet.Measles is a potentially severe disease, especially young children and persons with compromised immune systems. The majority of people who get measles were unvaccinated, the CDC warns.According to the CDC, the following states were reported to have measles:ArkansasCaliforniaConnecticutFloridaIllinoisIndianaKansasLouisianaMarylandMichiganMissouriNevadaNew Jersey New YorkNorth CarolinaOklahomaOregonPennsylvaniaTennesseeTexasWashingtonDistrict of Colombia"We continue to encourage parents to fully vaccinate their children," said infectious disease specialist Dr. Ulyee Choe. "Measles is a highly contagious disease that can have serious complications for babies and children."Unvaccinated individuals who are exposed to measles may be excluded for up to 21 days from public places such as school and work where they could infect others.Persons with symptoms of measles should be evaluated by their health care provider. Health care providers are asked to immediately report suspected cases of measles to the department of health. 1581
