The number of people killed worldwide by the coronavirus has exceeded 3,000, as China reported 42 more deaths.

More than 90% of the total deaths are in Hubei, the Chinese province where the virus emerged late last year. But there have also been deaths in 10 other countries, including more than 50 in Iran and more than 30 in Italy. Worldwide, there have been almost 90,000 confirmed cases, with the numbers outside China growing faster than inside China. But most patients have only mild symptoms, the World Health Organization said on Sunday, and the death rate appears to be between 2% and 5%. By comparison, the seasonal flu has an average mortality rate of about 0.1% but is highly infectious - with up to 400,000 people dying from it each year. Other strains of coronavirus, such as Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS), have much higher death rates than Covid-19.

What should you do if you think you have the virus?

Public Health England is advising anyone who has been to Wuhan within the past 14 days and has developed respiratory symptoms to phone NHS 111. Those symptoms include a cough, a sneeze, shortness of breath, or a fever. People who are concerned should phone ahead before going to any medical facility and mention their recent travel to the city. PHE also advises anyone travelling to China to maintain good hand, respiratory and personal hygiene, and avoid visiting animal and bird markets or people who are ill with respiratory symptoms. The agency is currently not advising people to wear face masks.
