Our latest work asks: How many tests for COVID-19 are being performed around the world? OurWorldInData.org/covid-tes… The chart compares the total number of tests performed per million people in a number of countries. Data for *many* more countries you find at the link above.

The #COVIDー19 virus can live on surfaces such as wood or stainless steel 24 hours or more. It is sensitive to disinfectants. So wipe those surfaces down, with a solution that’s 62% to 72% ethanol, .5% hydrogen peroxide, or 0.1% sodium hypochlorite #coronavirusaustralia

Social distancing - 1m,1.5m,2m,2.5m...? Lets do the science: 1960s 1m rule for droplet spread based on smallpox. 1940s flu spread 2.6m in lab. 1m rule for droplet disputed after SARS. USA now use 2-3m rule. Conclusion, COVID-19 distance not known, max distance better

Time to ramp up efforts. Better/enforced social distancing, testing all high risk groups (e.g. cruises), IT tracking for imposed isolation, close schools. #coronavirusau #COVID19Aus #auspol #ausbiz #wapol #nswpol #taspol #qldpol #Ntpol #sapol #vicpol

TIME TO DIAL UP EFFORTS #auspol @ANUmedia Better/enforced social distancing; testing all high risk groups (e.g. cruises); IT tracking for imposed isolation; close schools.

Lets do the maths: doubling on track every 3 days, no where near flattening out where doubling slows at every 6+days. Conclusion: Time to up efforts. Better/enforced social distancing, testing all high risk groups (e.g. cruises), IT tracking for imposed isolation, close schools.

Let’s do the maths: Monday approx 1,500 cases, Thurs 3,000 and so on. Full border lockdown is good but late; infected need support and monitoring. Home care for mild cases will increase the spread. Time for dedicated hospitals to reduce spread. #coronavirusaustralia #COVID19Aus

OPINION: Here’s what parents need to know about #COVID19 and how it can affect children. New #coronavirus piece published today by @UNSW Paediatric Fellow and Snr Lecturer @doctorvik and collaborators. @SCHNkids @westmeadkids @UNSWObGyn_Paeds. theguardian.com/commentisfre…

Lets do the maths: Monday approx 1500 cases, Thurs 3000 & so on. Full border lockdown is good but late; incoming need support & monitoring. Caring for mild cases at home will increase the spread. Time for dedicated hospitals to reduce spread.

#COVIDー19 is spread in the “droplets” of an infected person. These spread from the mouth outwards and then drop to the floor. One sneeze may produce up to 40,000 droplets.

Stay. At. Home. That means you, too, spring breakers.

Self-isolation for travellers and patients with mild COVID-19 is only as good as their compliance. Hong Kong has introduced electronic wristband for tracking.
