Chinese research shows that the death rate of nCoV increases significantly with patients 60 years of age and older.

The research results report published by the China Centers for Disease Control and Prevention (CCDC) today, based on 72,314 medical records, including 44,672 confirmed positive for nCoV as of February 11.

In these cases, CCDC identified about 81% of cases of minor illnesses, 13.8% of serious cases and 4.7% of critical cases. 49% of critical cases have died.

The study found an average mortality rate of Covid-19 epidemic was 2.3%, but the rate increased gradually by age group, especially for those aged 60 and over. Accordingly, the group of patients 40-49 years old has a mortality rate of less than 0.5%, while this rate among people aged 60-69 years is about 3.5%. The death rate among people 80 years of age and older is 14.8%.

This rate is calculated by the total number of deaths due to the disease divided by the total number of cases. In addition, people with underlying medical conditions, such as cardiovascular disease, also increase the risk of death.

The Covid-19 epidemic broke out in Wuhan from December 2019, appearing in 27 countries and territories. Worldwide, 73,332 cases and 1,873 people died from the disease. Five deaths were recorded outside mainland China in Japan, Hong Kong, France, the Philippines and Taiwan.

The Chinese military yesterday sent an additional 1,200 military medical doctors to Wuhan to deal with the corona virus, bringing the total number of military personnel in field hospitals in the city to 4,000. China's annual parliamentary session scheduled to open in early March could be postponed due to the epidemic.
