BACKGROUND: Severe acute respiratory syndrome coronavirus 2 has caused over 95 million confirmed cases of COVID-19 and over 2 million deaths worldwide. According to current literature data, older adults have higher risk of severe disease and mortality due to COVID-19. It is also known that older adults often do not present typical symptoms of diseases. The aim of the study was to assess if the prevalence of typical COVID-19-related symptoms varies by age group. METHODS: Medical charts of a random sample of COVID-19 patients dying in-hospital were retrieved through an integrated national surveillance system and reviewed by a group of researchers at the Italian National Institute of Health. Detailed information on COVID-19-related symptoms were extracted and analyzed. RESULTS: 3241 confirmed cases of COVID-19-related deaths were identified from 4391 reviewed medical charts. The mean number of COVID-19-related symptoms progressively declined with age, from 2.1 in patients aged < 60 years to 1.7 in those aged 90 years or older (p < 0.001). Moreover, fever, cough, and diarrhea significantly declined with increasing age. CONCLUSIONS: Older adults have atypical presentation of symptoms and may be paucisymptomatic. This may lead to a diagnostic and therapeutic delay which aggravates the prognosis of COVID-19. Special attention should be posed when assessing individuals aged 65 years and older with suspected COVID-19.
