Coronavirus R rate – the number that indicates how many people are infected for every one person – has dropped from 1.7. to 1.1 in England, research conducted by Imperial College London and Ipsos Mori suggests. The researchers suggest that the decline hints at the effectiveness of the government’s tougher posture. Despite the public outcry, the ‘rule of six’ measure may be supressing transmission, they suggest.
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.
Frailty is a standard classification employed by doctors to describe older people who find it difficult to recover from everyday illness, strains and accidents.
They are also more likely to have falls and end up in hospital when ill.
The study found that for one in five patients in hospital with COVID-19, delirium was their only symptom.
Among over-65s using the app, delirium was also more prevalent in frailer people with COVID-19 compared with more fit and healthy people of the same age with the infection.
For the frailer cohort, possible delirium was defined as having any symptoms of confusion, disorientation or drowsiness.
Tiredness and breathlessness were also common among frail app users.
And a third of app users who said they had experienced delirium did not have the classic symptoms of a cough or fever.
“Older, frailer people are at greater risk from COVID-19 than those who are fitter, and our results show that delirium is a key symptom in this group,” said Dr Rose Penfold from King’s College London.
Dr Penfold concluded: “Doctors and carers should watch out for any changes in mental state in elderly people, such as confusion or strange behaviour, and be alert to the fact that this could be an early sign of coronavirus infection.”
