Why is COVID so bad for the elderly?
We know coronavirus can be extremely, extremely dangerous for the older population. But why?
Australian researchers have been looking into this, and they believe it could be linked to repeated exposure to other seasonal coronaviruses.
In a study published in Nature Communications, scientists looked at blood samples from 89 healthy children, 98 adults, 57 elderly individuals and 50 COVID-19 patients, comparing antibodies to a range of coronaviruses, including SARS-CoV-2.
Lead author Amy Chung likened the immune memory response to SARS-CoV-2 to playing sport, with an older person's immune system thinking it had taken on the virus before.
"You have an opponent, and for the elderly, this is someone that in their minds is a team they have played multiple times beforehand," she said.
"They know the stats, and they know the key players to target."
