Doctors and carers should look out for signs of confusion or strange behaviour in frail older people because it could be an early warning sign of COVID-19, research suggests.
Even if they have no cough or fever, delirium is more common in vulnerable over-65s than other, fitter people of the same age. But it's not yet clear why this extreme confusion or delirium happens.
In this King's College London study, data from more than 800 people over the age of 65 was analysed. They included 322 patients in hospital with COVID-19, and 535 people using the Covid Symptom Study app to record their symptoms or log health reports on behalf of friends and family. All had received a positive test result.
The researchers found that older adults admitted to hospital who were classified as frail were more likely to have had delirium as one of their symptoms, compared with people of the same age who weren't frail.
For one in five patients in hospital with Covid, delirium was their only symptom.
The study calls for more awareness of it in hospitals and care homes.
