Symptoms of COVID-19 in patients infected with theOmicronstrain of the computer virus are " rather dissimilar " from those do by earlier strains and the still - prevalent Delta , a UK consultant on COVID-19 has said .

Speaking on Radio 4 ’s Today Program ,   Regius Professor of Medicine at the University of Oxford and a UK Government adviser on COVID-19 , Sir John Bell , said that data from South Africa , as well as theZOE COVID-19symptom study ,   showed that Omicron appear to be " behaving significantly differently " in paying attention to the clinical picture .

The information , which he stresses only show us the former stage of the disease , due to the minuscule amount of metre that has elapsed since Omicron ’s discovery , appears to   suggest there are some newfangled signs to appear out for , that were less rife in early strain , such as Alpha and Delta .

" I recollect one of the few thing we do know is the syndrome is rather dissimilar . We do get laid that it ’s behaving rather other than . It attend like the symptoms of this are stuffy nozzle , sore throat , " hesaid on the programon Tuesday , adding " myodynia   – which is basically ache muscles   – particularly around the back are very characteristic of this , and no - one do it why that is . "

" People also have a second of gut upset . They have a bit of loose crapper , those variety of things . "

The moving-picture show is , of course , still evolving , and the   US Centers for Disease Control and Preventioncurrently writesthat the most ordinarily reported symptom are " cough , fatigue , and congestion or runny nozzle " , though   – like with other variants   – this will likely switch as more data comes in .

Bell went on to say that we still do not know a lot about Omicron , particularly with regards to later stage of the disease , though we will soon get an insight into this as data comes in from South Africa , where the strain was first identified .

" We know this is a highly , highly infective variant . Two to three times more infectious than Delta , which was already a pretty infectious variant on its own , " he said in the audience . " What we ’re still waiting for is the data of what is the consequence of that [ … ] from a clinical perspective . "
