ARI SHAPIRO, HOST:
As the U.S. opens back up, coronavirus clusters are popping up all over the country. A cluster is where multiple people contract the disease at the same event or location. Health officials are scrambling to identify those clusters so they can get in touch with people exposed to the virus who might need to get tested. To hear how those efforts are going and what we're learning from them, we are joined now by Erika Lautenbach. She's director of the Whatcom County Health Department in the northwest corner of Washington state.
Good to have you here.
ERIKA LAUTENBACH: Thanks for having me, Ari.
SHAPIRO: So Whatcom County in Washington state are not seeing the spike in cases that other parts of the country are experiencing, but you are seeing an increase. What have you learned about who in your area is getting COVID-19 right now?
LAUTENBACH: Sure. We're definitely seeing an increase in Whatcom County, and we have seen almost a near flip in the cases that we're experiencing. So in April of this year, we were really struggling with long-term care outbreaks. So about 3 out of 4 people were over the age of 30 and really pretty heavily skewed to 60-plus. And by contrast, in June, we're seeing that now 2 out of 3 people that have contracted the disease are under 29.
SHAPIRO: Does the fact that young people tend to be getting this mean that people are going to have a better chance of surviving the disease now since it tends to be worse for older people?
LAUTENBACH: I would say yes and no. The concern is that because these younger people are having more mild symptoms, they are going to work sick. They are visiting with their parents and grandparents sick. And they're continuing to go to social events where they expose more and more people. So when we think about that web of spread, that web just grows and grows and grows.
SHAPIRO: Can you give us an example of a cluster you've identified and how you traced the cases that arose from it?
LAUTENBACH: So we found in our investigations in early June that there was a party with somewhere between a hundred and 150 people outside. And from our investigations, we identified that 14 cases were associated with that party. And subsequently, an additional 15 cases were associated with those initial cases. So that one event spread to 29 people and 31 related employers.
SHAPIRO: And just to clarify, how much farther do you trace it after that? I mean, presumably, at least one of those second- or third-tier infections would lead to a fourth- or fifth-tier infection.
LAUTENBACH: Yes. And that's our challenge - is to continue to trace as this moves through families, as it moves through workplaces, as it moves through additional social events as well.
SHAPIRO: There's been a lot of concern over whether racial justice protests could spread the virus. Did you have those gatherings in Whatcom County? And if so, what did you see?
LAUTENBACH: Yeah. We did have a rally in Bellingham, which is our county seat. And there was also a protest. And we have not been able to connect a single case to that rally or to the protest. And what we're finding is, in large part, that's due to the use of masks. Almost everyone at the rally was wearing a mask. And it's really a testament to how effective masks are in preventing the spread of this disease.
SHAPIRO: It's incredible that there hasn't been a single case traced back there.
LAUTENBACH: Yeah, it's actually surprising for us as we continue to investigate new cases. We're finding that the social events and gatherings, these parties where people aren't wearing masks, are our primary source of infection. And then the secondary source of infection is workplace settings. There were 31 related employers just associated with that one party because of the number of people that brought that to their workplace. So for us, for a community our size, that's a pretty massive spread.
SHAPIRO: Erika Lautenbach is director of the Whatcom County Health Department in Washington state.
And we appreciate your talking with us today. Thank you.
