According to a report by Chinese researchers, most people infected with the new coronavirus in China suffer from mild symptoms, with older patients and those with underlying conditions most at risk from the disease.
Nearly 1,900 people have now been killed by the disease and more than 72,000 have been infected in China since it first emerged late last year in central Wuhan.
As of February 11 a paper published in the Chinese Journal of Epidemiology examined 72,314 confirmed, suspected, clinically diagnosed and asymptomatic cases of COVID-19 disease across China.
It’s the largest study on patients with novel coronavirus since the outbreak began late December.
Here are the main findings from the Chinese Center for Disease Control and Prevention (CCDC) paper:
Elderly, at-risk sick
About 80.9% of infections are moderate, 13.8% as serious and only 4.7% as severe.
The highest mortality rate is at 14.8 per cent for people 80 and older.
The study finds that patients with cardiovascular disease are most likely to die from novel coronavirus complications, followed by diabetes patients, chronic respiratory disease and hypertension.
Kids up to 9 years of age didn’t die, following at least two cases of infected babies via their mothers.
The death rate remained low at 0.2 percent until age 39.
The rate of fatality increases progressively with age. It is 0.4% for people in their 40s, 1.3% in their 50s, 3.6% in their 60s and 8.0% their 70s.
Men are more likely to die than women (2.8 per cent) (1.7 per cent).
The average rate of death from the virus was 2.3 per cent.
While the 2002-2003 outbreak of (SARS) affected fewer people, the rate of fatality was almost 10 percent.
The U.S. Centers for Disease Control says between 26 million to 36 million Americans contracted seasonal flu between October 2019 and February 8 this year, with deaths ranging from 14,000 to 36,000-a death rate of about 0.1%.
