1/ According to the ONS prevalence survey, symptoms of the 'new' B.1.1.7 #COVID19 variant don't seem massively different to the 'old' variant. Cough, sore throat, fatigue & muscle ache a bit more common. Loss of smell/taste a bit less common.

2/ Cough (35% new, 28% old)
Fatigue/weakness (33% new, 29% old)
Headache (32% new, 30% old)
Muscle ache (25% new, 22% old)
Sore throat (22% new, 19% old)
Fever (22% new, 19% old)
Loss of smell (15% new, 19% old)
Loss of taste (16% new, 19% old)
Breathlessness (12% both)

3/ Nausea/vomitting (10% both)
Diarrhoea (7% both)
Abdominal pain (7% both)

Differences in severity and duration of symptoms for those non-hospitalised still unknown. Is #LongCovid more or less common with new variant?

4/ What would also be useful to analyse @ONS is the % of people who're symptomatic but don't have *any* of the 'classic' symptoms listed on NHS website as indication to seek testing (cough, fever, loss of smell/taste). So basically analysis of *combination* of symptoms in people.
