SAN DIEGO (KGTV) — With California setting single-day records this week for COVID-19 cases, experts say it’s important to keep in mind that some activities carry a higher risk of transmission than others.To gauge risk, it’s helpful to think of it like an equation, said Dr. Tyler Smith, a professor and epidemiologist at National University.First, consider the environmental factors like whether the activity will be indoors or outdoors and the number of people likely to be present.Then consider the likelihood of successful safety measures: whether people will wear masks, clean surfaces, and maintain six feet of distancing.Compare those two datapoints, and you can assess the overall risk of an activity, Smith said.A good example of the importance of this equation is the dentist’s office, our experts said.On one hand, the environmental risk factors are high. Working in someone’s mouth with drills can aerosolize particles that carry the virus.But dentists are likely to strictly observe public health countermeasures like personal protective equipment and sanitization, to balance out the risk equation.“Our doctors offices and dental offices are really some of the safest places right now,” said Dr. Georgine Nanos, a family physician who specializes in epidemiology.Dr. Smith agreed: dental offices are low risk.The likelihood that participants will wear masks is a critical part of the safety equation, according to Dr. Nanos.“What [the medical community] didn’t know four months ago is that wearing a mask can reduce the risk of transmission and catching COVID-19 by sometimes up to 60 percent if both people are wearing masks,” she said.Gyms are an environment where some may try to avoid wearing a face covering during a challenging workout.“If you can be 6 feet apart from your neighbor, that would be ideal. I wouldn’t recommend a hot yoga class where people are crowded together and not a lot of ventilation,” Dr. Nanos said.If you can maintain distance and bring your own sanitizer, ideally in a room with high ceilings and good ventilation, Dr. Nanos grades gyms medium risk.In the high-risk category, experts agree bars pose a particular challenge. Not only is there a chance you could encounter a large crowd indoors, alcohol could discourage social distancing efforts.Also high risk: casinos. In addition to alcohol, casinos have an environment with a lot of touchpoints like slot machines and chips. Many also allow indoor smoking, which could complicate health matters, Dr. Nanos pointed out.But the highest risk activity, according to both experts, is protests and rallies.“That many people together, not distancing, rarely wearing masks and yelling,” Dr. Smith said, That to me is terrifying as a public health professional.”They put large protests and rallies at the top because unlike other environments, there is no one in charge with a financial stake in maintaining public health countermeasures.Dr. Smith said any of these activities have the potential to be operated safely.“It just has to do with people realizing they have to adhere to these mandates. If so, all these things can be open. We’ll still have cases but it won’t overwhelm our healthcare system,” Dr. Smith. 3212

SAN DIEGO (KGTV) — With COVID-19 cases spiking in parts of the country, some of the largest testing providers are struggling to keep up with the demand, complicating efforts to isolate infected individuals and trace their contacts.Quest Diagnostics announced Monday its turnaround time for most test results had expanded to four to six days, back to where it was in the beginning of April. Quest said its turnaround time for priority tests -- those for hospitalized patients and symptomatic healthcare workers -- remained at one day.San Diego County operates 33 free testing sites for COVID-19, but ABC 10News found turnaround times can vary.Have you waited more than 7 days for COVID-19 test results? Email our reporter.Team10’s Adam Racusin got his negative test results from the site in Lakeside back in three days.The county’s goal is to report all test results within three days, although the current average is between three and five days for non-priority tests, according to County Health and Human Services Agency Director Nick Macchione.The county typically reports priority tests within 24 to 48 hours for vulnerable populations like individuals at skilled nursing facilities and first responders, he said.I visited the testing site in the SDCCU Stadium parking lot and got my negative test results back in seven days, after I placed a call to the County Nurse Line inquiring about them.“It’s about resources,” said County Public Health Officer Dr. Wilma Wooten.Wooten suggested that the recent spike in demand could be playing a role in increased wait times for results.The county uses its own lab to test samples, but when the lab gets backed up it sends samples to private labs that have been inundated with demand.In addition to Quest, Lab Corp and CVS Minute Clinic have reported long waits linked to high demand in recent days.In hard-hit Arizona, ABC News reported that some people are waiting up to 10 days for results."When we tell them, go home, self-isolate, quarantine yourself until we get back to you and that period of time is a week to 10 days, people start to kind of diverge from those suggestions within a few days,” said Dr. Tyler Smith, a professor and epidemiologist at National University.He said not only can testing delays lead to more infections if people waiting for results venture out in public, the added time makes contact tracing more difficult.There are already signs of strain on the county’s ability to do contact tracing: as of Monday, the county was able to launch just 57 percent of its case investigations within 24 hours, setting off one of its warning triggers.The county says it is taking steps to speed up testing in its lab, including adding staff and securing new testing equipment that has yet to arrive. The county has also added shifts at the lab, going with up to three shifts a day to process specimens.As the number of cases grows in San Diego County, there could be future delays in turnaround time at the county lab, “but likely not beyond where it is today,” said spokesman Tim McClain.“Everyone should be practicing social distancing, good handwashing and wearing of a face covering,” he said via email. “Individuals who felt symptomatic or otherwise had a strong belief they had the virus should isolate themselves and follow other public health precautions until the results come back.” 3362
