Epidemiology and Clinical Presentation of COVID-19 in Older Adults

SARS-CoV-2 infection remains asymptomatic in 33 to 90% of older adults depending on their immune status from prior infection, vaccination and circulating strain. Older adults symptomatic with SARS-CoV-2 often both present atypically, such as with a blunted fever response, and develop more severe disease. Early and late reports showed that older adults have increased severity of COVID-19 with higher case fatality rates and higher intensive care needs compared to younger adults. Infection and vaccine-induced antibody response and long-term effects of COVID-19 also differ in older adults.
