As of 23 March, there were 336,000 confirmed cases of COVID-19 in the world, with more than 250,000 cases outside China. Despite these numbers, much is still misunderstood or unknown about the virus which has brought regions of the globe to a standstill and placed huge pressure on the global economy.

Even what we do know – that elderly people are more at risk, that this is a new virus but resembles other known epidemics, that it is highly infectious – requires more explanation.

Here, Belgian virologist Guido Vanham, the former head of virology at the Institute for Tropical Medicine in Antwerp, Belgium, helps answer questions about COVID-19’s origins, its behaviour and its future.
