The number of deaths related to the novel corona virus reached 100,000 on Friday, according to a Reuters balance sheet, that 1.6 million cases have occurred.
The first death occurred on January 9 in the central Chinese city of Wuhan. It took 83 days for the first 50,000 deaths to be registered and only eight days for the number of victims to rise to 100,000.
The number has accelerated between 6% and 10% every day over the past week, and nearly 7,300 deaths have been reported worldwide on Thursday.
The death toll is now comparable to that of the Great Plague in London in the mid-1660s, which killed an estimated 100,000 people, about a third of the city's population at that time.
But it's still a long way from the so-called Spanish flu that started in 1918 and is estimated to have killed more than 20 million people when it faded in 1920.
The novel corona virus is believed to have appeared at a Wuhan market where wild animals were sold at the end of last year. It spread quickly in China and around the world.
There is still a lot to decide, including how deadly it is. Estimates vary widely.
Friday's numbers – 100,000 deaths in 1.6 million cases – indicate a death rate of 6.25%, but many experts believe the actual rate is lower because of many mild and asymptomatic cases in which infected people have no symptoms show sums not included in the case.
Some countries, including Italy, France, Algeria, the Netherlands, Spain and the UK, report that more than 10% of all confirmed cases have been fatal.
One of the largest disease death studies involving 44,000 patients in China estimated the rate to be around 2.9%.
The same study reported that 93% of registered deaths were people over 50 and over half were over 70.
Nevertheless, there is a growing number of young adults and teenagers who are included in the worldwide toll.
While North America now accounts for more than 30% of cases, Europe has reported a disproportionate number of deaths as countries with older populations such as Spain and Italy are severely affected.
Southern Europe alone is responsible for more than a third of deaths worldwide, although only 20% of cases have been registered.
In many countries, official data only include deaths reported in hospitals, not in homes or nursing homes.
