if we dont have a system then authorities may wait too long to react.

Everyone outside the household should sadly be assumed as potentially infectious (COVID can be spread before symptoms developed) & never let your guard down - stay 1.5m away & never take your mask off in public transport/taxi/uber/shared car, meeting & tea-room. It will improve❤️

Its reliant on case detection and my observations factors thus into the 100 cumulative cases over 14-days.

There maybe a strategy that we don’t know about but my trafgic light system reflects difficulty of controlling cases once total gets to 100 over 14-days.

😁Decline in ’change in 14-day totals’ in Vic & NSW says 2nd wave coming under control. Congrats Victoria ❤️. 14-day total traffic light I use: 'green' open border (less than 59 cases), amber 'wear a mask' (60-99), Red hotspots 'ring fence or curfew' (100+)

I agree with @MackayIM Also Phase 3 trials will answer if those recovered from covid do poorly with a vaccine and if elderly need a different vaccine to aid their immune response. 🤞

Hello Batgirl - COVID-19 droplets survive on hard surfaces (infectious dose not yet known). If concerned, wipe over takeaway package. No infection has been found from eating food and cooked food. 😋
