Know your enemy

Labs around the world are working around the clock in a bid to understand humanity’s newest foe – the new coronavirus. Three crucial questions are occupying virologists. What makes the virus so good at infecting people? How does it reproduce so quickly once it is inside us? And why doesn’t the virus cause symptoms straight away, allowing it to spread undetected? The answers will suggest ways to treat the disease and develop vaccines.

One team has already used electron microscopy to determine the atomic structure of “spike” proteins on the outside of the covid-19 virus, which are crucial for letting it latch onto host cells. With this information, inhibitor drugs can now be designed to block it from attaching to a human cell.
