Ask an epidemiologist: Harvard's Marc Lipsitch answers your COVID questions

Do masks really protect us? Are children less vulnerable to COVID-19? And why do scientists hope you avoid indoor bars?

Marc Lipsitch is a Professor in the Department of Epidemiology at the Harvard T.H. Chan School of Public Health and the Director of the Center for Communicable Disease Dynamics.

Viktor Orban's authority in Hungary; uptake of contact-tracing apps

Carl Bildt, former Prime Minister and Foreign Minister of Sweden, with the view from Europe:

Technological Revolution & Surveillance in the COVID-19 Era

Are we in the middle of a technological revolution?

Yes? I feel like a technological revolution should feel more empowering and exciting. It should feel like something good as opposed to something catastrophic.

Trump will say, if I had done nothing, we would have 2.2 million deaths, framing for advertising. But it's hard to sell that.

Well, the basic idea is that if you opt in to one of these apps, your phone will use Bluetooth, it will scan, look for other devices that are also being used by people who have opted in. If one of you test positive for coronavirus, the other will get a notification and can then take corrective action. There are a lot of different ways these are being built, but that's the idea.
