Coronavirus study reveals greater risks from middle age

April 1, 2020 - The first comprehensive estimates of hospitalisation and death rates from coronavirus disease (Covid-19) in mainland China have revealed a considerable increase in risk for patients from middle age.

The study found that the proportion of deaths from both diagnosed cases and from milder, unconfirmed cases is strongly influenced by age – ranging from 0.0016% in 0 to 9-year-olds to 7.8% for people aged 80 and above.

Differences in hospitalisation rates by age were also reported, with nearly one in five over-80s infected with Covid-19 likely to require hospital care, compared with around 1% of people under 30.

The analysis, published in The Lancet Infectious Diseases journal, estimated the overall death rate, including unconfirmed cases, at 0.66%. While the figure is lower than some recent estimates for Covid-19, it is still much higher than the 2009 pandemic “swine flu” virus, which was estimated to be fatal in around 0.02% of cases.

The authors note that the data does not separate out the effect of underlying health conditions, which often correlate with age.
