joining me now from the university of massachusetts dartmouth, aaron bromage.ur mind an absolute certainly to happen, regardless of how people try to mitigate with masks and social distancing? >> well, it's an absolute certainly that when you increase interactions between people you are giving a greater opportunity for this virus to find a new body to grow in. so as we are reopening, as we're having more contacts, where there's just more opportunities for transmission, there is not a certain with this. we can't predict the future, but based on the biology, the more interactions the people have, the easy it is for the virus to spre spread. a flat curve still means we're right at the top, the plateau of the peak, which means there's a lot of infected people still out in the community. if the interactions start again, if you've got 1,000 cases per day, by the end of the week you could have 2,000, then 4,000. it can just increase very, very quickly. so it's a matter of how many cases a day you have in your community about how the risk should be perceived and taken

joining me now is aaron bromage, professor of biology at university of dartmouth and he's written aboutmaybe shouldn't go. professor, thank you so much for being with us today. you've written this blog post that has 10 billion views, roughly, the reason is i think it is very relatable for people. i want to put up the list of places where 90% of coronavirus viruss are happening. i'm going to leave home out of it, that's person to person, if your husband, your wife, your kid has it, you get it from them. all of them have something in common, they're largely inside with a bunch of other people. what does that tell you? >> so what we're seeing, you know, in places doing really great contact tracing, and mapping what is happening with the spread of infection, they're seeing that these enclosed spaces with lots of people and poor air circulation leads to the fairly rapid spread of the virus among people. >> i want to give a visual representation of this. they heard about this choir practice in washington state. i want to put up a map of this. 45 of 60 choir members were infected, two died aft

joining us now with the answers on how to weigh all of these risks is aaron bromage, a comparative immuneologistat the university of massachusetts-dartmouth, which is a very beautiful place to be this time of year. so take us through how we calculate our risks of exposure in these various environments. >> so you're just going to look at these different environments. the biggest risks of exposure come from being indoors with a room that has poor air exchange and with lots of people. so whenever you put yourself into that situation, the risk just starts to elevate and go up. and if you get into that situation where you have, you know, people talking or yelling or singing, it just increases the risk because more of what comes out of your mouth, those respiratory droplets, more of those are expelled into the environment, which then just increases the opportunity for you to inhale them in. >> and you mentioned in the piece you wrote about, for example, that singing is the most dangerous of all of those things, that more comes out in singing than in just speaking. >> yeah. so just breathing, it's a fa
