How deadly is coronavirus?How deadly is coronavirus?
The proportion dying from the disease appears low (between 1% and 2%) - but the figures are unreliable. The proportion dying from the disease is likely below 1% - but there will still be uncertainty until better testing reveals how many people have been infected.
Thousands are being treated but may go on to die - so the death rate could be higher. But it may also be lower if lots of mild cases are unreported.

Coronavirus spreads when an infected person coughs or sneezes small droplets - packed with the virus - into the air. These can be breathed in, or cause an infection if you touch a surface they have landed on, then your eyes, nose or mouth.Coronavirus spreads when an infected person coughs or sneezes small droplets - packed with the virus - into the air.
