1st 3 mths of 2020: 18m airport arrivals fuelling onset of disease in UK
Govt not learning from best practices elsewhere incl #CovidTesting on arrival. It isn't perfect but will help minimise risk in uk.
2nd test 7d later needed for asymptomatic carriers https://www.bbc.co.uk/news/health-53567309

Integration of intnl #CovidTracing in EU is a key element in UK resilience against future resurgence.
It needs to be effective now & is an abject failure of govt.
A system needs to be in place for other notifiable diseases too incldg animal & plant health

Effective #CovidTracing is the only mechanism which can limit health, social & economic impact globally.
An absolute priority must be overcoming constraints in sharing data formats & security systems

great thread of a review of #CovidShedding.
Suggests active viral shedding is up to 9d, confirming a need to review days spent in isolation if symptomatic
