According to a recent Chinese study, coronavirus mortality in China may be lower than previously estimated.
The data, published in the prestigious Lancet magazine, is based on figures published by the China Center for Communicable Diseases in February for more than 70,000 cases, which were widely reported in early March. However, it has now been possible to refine the estimate by taking into account mild and thus undiagnosed coronary infections.
Old age and basic diseases are currently considered to be the biggest risks for the Crown. The new study only takes into account the age of the patient, but the underlying diseases are not specified.
In a new study, an international team of researchers concluded that 0.66 percent of those infected in China would die. If the death toll were counted only from confirmed cases, the mortality rate in China would increase to an estimated 1.38.
The general perception of the corona at present is that up to 80% of cases are asymptomatic or mild.
The new estimate also has a dramatic impact on the forecasts for some age groups. If mortality is viewed only through diagnosed cases, Korona took the lives of nearly 15 percent of Chinese over-80s. Taking into account asymptomatic and mild cases, the new calculation gives a figure of just under 8 percent. The death rate in the seventies is also halved from eight to about four.
There is no impact on children and adolescents, as they were virtually non-existent among the Chinese dead.

Although the new study provides encouraging information about mortality, it does place a burden on medical care. According to the calculations, almost one in five people over 80 who receive a crown will be hospitalized. Even middle-aged people in their fifties would need 8% of hospital care.
Researchers note that it is difficult to compare mortality rates between countries because of differences in testing practices, for example. In addition, the age distribution of the countries varies. However, the study further strengthened the notion that the disease is most dangerous for the elderly.
The study is based on official figures from the Chinese on the dead, which have since been questioned as possibly lower-ranking.
However, according to Tuomas Aivalo, a postdoctoral researcher at the University of Helsinki, Lancet research is the first reliable estimate of covid-19 mortality in all cases of infection. However, he emphasizes that this is only an assessment of China.
In other studies, the corresponding mortality rate in Europe, according to Aivalo, ranges from 0.8 to 1.2%.
