With global attention on the Wuhan coronavirus and its spread around China and other countries, it's important to put it in the context of other deadly infections, including seasonal influenza, which claims the lives of thousands of people every year.

According to a September 2019 study by Chinese scientists in The Lancet, there are an average of around 88,100 influenza-related deaths every year in China, with a mortality rate of between 1.6% and 2.6%. The majority of those who died as a result of the flu were aged over 60, the report said.

While the true extent of the new coronavirus is unclear, it appears to be more deadly than seasonal influenza. Of the 846 confirmed cases, there have been 26 deaths, a mortality rate of 3%.

However, that is far less deadly than related coronaviruses SARS and MERS. SARS has a mortality rate of around 10%, while MERS has killed 34% of those infected with that virus.
