Professor of Epidemiology @UNSW with an eye on infection at all times. Advisor to @WHO Health Emergencies IPC Preparedness, Readiness and Response to COVID-19
Perhaps difficult for staff not trained in PPE to continuously comply for 8hour shift esp in lunchroom and risk of spread to colleagues carpooling, smoke break & socialising. Imperative to use rapid antigen testing at end of every shift before going home.
Graphs illustrating weekly tracking of Testing vs Pos results. Safety zone is when testing is high and positives low. Vic 😀, NSW improved 👌. QLD needs improving, SA 😟 ramp up testing. There's never a time to drop rate of testing, ever.
Current 14-day case load is 5. Important not to rush decisions without results, tomorrow or Tuesday test results from contacts and their contacts will confirm whether cluster over 11 households has been contained. Vic you're so close to very safe level.
Post lockdown strategy: increase testing combined with forward & back contact tracing and isolation of every contact (because 14%-20% cases are asymptomatic, every case is infectious from day-3 post-exposure & some wont test positive first time)
Choose countries for home quarantining based on similar epidemiology and leadership for rapid response to cluster outbreaks. Testing rates per million if low may hide hi risk to our community (e.g.UK). UK, EU now in savage 2nd wave; USA numbers continue skyward
This is my 14 day rolling average. NSW is in the Amber zone (60-99 cases over 14 days. Too high and took 30 days to get out of RED (100+). Now Amber but climbed again. Still concerning
who.int/publications/i/item/… Transmission within children & staff is limited. Guideline for 12yrs+ made on dexterity & possible higher risk of COVID than 0-11yrs. Benefits must outweigh risks.
During SARS review I wrote of the concept of warning levels in pandemics/epidemics similar to those used for typhoons/bushfires and so easily understood by everyone. Some details for COVID: theage.com.au/national/victo…omny.fm/shows/mornings-with-…
Agree regionalising a response will work if we can manage those moving into and out of those regions (e.g.masks on drivers of essential goods when they arrive from areas of greater case numbers; faster response for small spot clusters like Batemans Bay to prevent spread)
