Inflammaging and COVID-19

I pass on the first paragraph from a Science Perspectives article by Akbar and Gilroy, and suggest that you have a look at the whole article.
Aging is associated with increased morbidity arising from a range of tissue dysfunctions. A common denominator of age-associated frailty is increased baseline inflammation, called inflammaging, that is present in older individuals. Recent studies have shown that the presence of excessive inflammation can inhibit immunity in both animals and humans and that this can be prevented by blocking inflammatory processes. This finding has important implications for the immunity of older individuals who are infected with pathogens such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that induce overwhelming inflammation, which can be fatal, particularly in older people. Reducing inflammation may be a therapeutic strategy for enhancing immunity in older people.
