In case of older adults, you must look for signs of delirium, which is suggested to be an early warning sign of COVID-19 infection in senior citizens. As per a different study, delirium was the only symptom in several older patients who tested positive for the virus. Delirium is referred to as a state of confusion, inattention, disorientation, and other cognitive change. The finding of this study suggests that patients hospitalised for COVID-19, especially who needed ventilators, are known to be vulnerable to delirium, which could be due to the isolation imposed to limit coronavirus spread.
