New research suggests that care home residents should be tested even if they are feeling generally unwell, as those with coronavirus may be asymptomatic or not display typical symptoms.

According to the study by the University of East Anglia (UEA) and North Norfolk Primary Care, supported by UEA Health and Social Care Partners, in many cases symptoms were not typical and did not include a high temperature, cough or loss of smell.

Instead, residents who tested positive for Covid-19 often presented as generally unwell, researchers say in the study which has not yet been peer-reviewed.
