did they still get to count that false positive as a case.?

[h=1]CDC guidelines say wearing a mask during prolonged exposure to coronavirus won't prevent possible infection[/h]
Guidelines from the Centers for Disease Control and Prevention state that those who come in close contact with someone with the coronavirus for more than 15 minutes could spread the virus regardless of whether either party wears a mask.
“Wondering what @cdcgov really thinks about masks? Their guidance on quarantining after exposure to someone with #covid explicitly states whether the infected OR exposed person wore masks doesn’t matter,”
The CDC states on its Public Health Guidance for Community-Related Exposure page that those who come in close contact with people showing COVID-19 symptoms or someone who has tested positive for the virus can spread the infection whether or not they are wearing masks.
CDC states that "data to inform the definition of close contact are limited." Factors "to consider" when defining close contact are duration of exposure, proximity to an infected person, and whether or not that person is presenting symptoms. Data for what a prolonged exposure is are iffy; however, longer than 15 minutes can be considered an operational definition, according to the CDC.
“This is irrespective of whether the person with COVID-19 or the contact was wearing a mask or whether the contact was wearing respiratory personal protective equipment (PPE),” the CDC states.
“While research indicates masks may help those who are infected from spreading the infection, there is less information regarding whether masks offer any protection for a contact exposed to a symptomatic or asymptomatic patient,” the guideline states. “Therefore, the determination of close contact should be made irrespective of whether the person with COVID-19 or the contact was wearing a mask.”

The CDC released a meta-analysis in May 2020 of 14 controlled, extended trials studying the effects of mask usage. The study found no reduction in the rate of laboratory-confirmed cases of influenza, a similar respiratory illness.
Leading Swedish epidemiologist Dr. Anders Tegnell, however, dismissed the idea that masks alone will "solve" the pandemic, citing “astonishingly weak” scientific evidence.
“The findings that have been produced through [the use of] face masks are astonishingly weak,” he told the German outlet Bild this month.
“I’m surprised that we don’t have more or better studies showing what effect masks actually have. Countries such as Spain and Belgium have made their populations wear masks, but their infection numbers have still risen. The belief that masks can solve our problem is, in any case, very dangerous,” he said

"It's still - just - summer. Respiratory viruses don't circulate as well in the summer months. We are still spending time out of doors. Most of us are social distancing: I can't remember the last time I shook hands with anyone. So the virus has had less chance to jump from one person to the next. But coronavirus is still out there.The next few weeks are going to be critical in understanding whether transmission rates will rise sharply again as schools and universities go back and people return to offices and spend more time indoors.
"We know that winter in the northern hemisphere is when respiratory viruses really take off. So this is not over yet, and things could get an awful lot worse," says virologist Prof Wendy Barclay, from Imperial College London.
There are already worrying signs from France where not only cases, but Covid-related illness is increasing.
