The coronavirus outbreak, which originated in China, has infected more than 550,000 people. Its spread has left businesses around the world counting costs.
Here is a selection of maps and charts to help you understand the economic impact of the virus so far.
Global shares take a hit
Big shifts in stock markets, where shares in companies are bought and sold, can affect many investments in pensions or individual savings accounts (ISAs).
The FTSE, Dow Jones Industrial Average and the Nikkei have all seen huge falls since the outbreak began on 31 December.
The Dow and the FTSE recently saw their biggest one day declines since 1987.
Investors fear the spread of the coronavirus will destroy economic growth and that government action may not be enough to stop the decline.
In response, central banks in many countries, including the United Kingdom, have slashed interest rates.
That should, in theory, make borrowing cheaper and encourage spending to boost the economy.
Global markets did also recover some ground after the US Senate passed a $2 trillion (£1.7tn) coronavirus aid bill to help workers and businesses.
But some analysts have warned that they could be volatile until the pandemic is contained.
