Hong Kong has achieved one of the lowest infection rates in the world during the current outbreak, thanks in part to rigorous testing and tracing measures. With no new cases for several days in a row, this Asian financial center is now beginning to ease restrictions, using methods grounded in epidemiological research and political planning. Our host James Chau looks at the science-based approach that has shaped Hong Kong's response, and how its experience facing SARS almost 20 years ago has prepared the city and its people.

While much of the world is still sheltering-in-place, Wuhan, the original epicenter of the global outbreak, has been declared virus-free. At its peak, Wuhan saw over 15,000 new cases a day.

Our host James Chau explores how the citizens of Wuhan recovered from one of the most traumatic events in modern history, giving insight into what comes next for countries on the road to remission.
