    In our observational cohort study of the exhaled breath particles of 194 healthy human subjects, and in our experimental infection study of eight nonhuman primates infected, by aerosol, with SARS-CoV-2, we found that exhaled aerosol particles vary between subjects by three orders of magnitude, with exhaled respiratory droplet number increasing with degree of COVID-19 infection and elevated BMI-years.

    Q. How confident are you that the Chinese are doing what needs to be done?

    A. They're doing things that have completely broken the paradigm of how you respond. They have been, in a draconian way, shutting down everything. They have locked down 50 million people, including the entire 11 million-person city of Wuhan. They will not allow anyone into Beijing unless they have a 14-day quarantine. They're essentially locking people who test positive in their houses. I mean, they're doing things that are almost unheard of in the annals of public health.

    Q. Will it work?

    A. As unusual and extreme as it is, it might actually, ultimately, have an effect. There's this report that the number of new cases for the last couple of days in China has gone down. I don't put much strength in that unless I see it really start to come down and down and down. A few days of going down doesn't mean anything to me. But if it continues to go down, that might be a signal that they're having an effect of what otherwise would be extreme means.

    Q. That would never happen here, would it? Locking down 50 million people?

    A. No, not a chance. It would never happen.
