(Dr. Andrew Bayliff)
‘First wave’
Most testing hospital based
Patients presenting with relatively severe symptoms
Self-selecting sample
Biased towards older patients with comorbidities
Most positive cases never tested, therefore undiagnosed
Many asymptomatic and mild cases
‘Current wave’
Much more testing
Many via track and trace
Therefore picking up a representative sample of the total infected population
Mortality rates for recent ‘cases’ will be biased more towards the statistically true outcomes
i.e. the true IFR
Testing rate is more than x100 from the early weeks
‘chalk and cheese’
‘apples and oranges”
Q and A
Will this vaccine change my DNA?
Contact tracing apps can sharply reduce the spread of Covid-19 even when only a few people use them
Non-pharmaceutical interventions
Google and Oxford University
An app used by 15% of the population
Together with a well-staffed contact-tracing workforce
Can lead to a 15% drop in infections
And an 11% drop in deaths
Google and Apple.
Bluetooth signals
Anonymously notifies a person if someone they met contracts Covid-19
