Prevalence of Symptoms in Patients with COVID-19 by Age Group
(Click on hyperlinks to access more detailed data)
The most commonly reported symptoms for elderly (>65 years old) individuals were fever, cough, and dyspnea. Among elderly populations diagnosed with COVID-19, we found that fever and cough are slightly more prevalent compared to other age groups, while dyspnea is much more common in the elderly.
Children (median age ranged from 3-8 years old and age range of 0 – 16 years) had more heterogeneous presentations with fever and cough being consistently the most prevalent, followed by a low prevalence of diarrhea and headache. The prevalence of most symptoms assessed was least common in children compared to adults and the elderly.
Most notably, fever and cough were less prevalent in children compared to other age groups. Children presenting with a broader spectrum of symptoms may contribute to the difficulty in diagnosis and assessing prevalence among children.
