No statistical significant benefit for masks vs no masks in the results of a study in 123 schools in England which used masks and compared that to others that did not during the Delta wave of Covid.

- Finally a randomised study of N95 vs medical masks PCR confirmed COVID occurred in 52 of 497 (10.46%) participants in the medical mask group versus 47 of 507 (9.27%) in the N95 respirator group (hazard ratio [HR], 1.14 [95% CI, 0.77 to 1.69]).
- There is ongoing debate as to whether widespread use of N95 masks in the community would decrease infections more than surgical masks. There are no good studies that answer this question, but this data from Germany suggests that their widespread use in Bavaria didn’t help.
- Victorian government intends to extend the lockout of the unvaccinated throughout 2022. This is disproportionate to the risks the unvaccinated pose in a population that will reach at least 93 per cent two-dose coverage by year’s end.
- Epidemic curve for Australia tonight from Comm Health website. Still early but epidemic curve looks like its falling. Hopefully that fall will continue and what we are doing now will cause it to keep on falling.
- Children did not increase your risk of getting infected with Covid. Nor did school attendance. Very large study from Scotland "In our large cohort, adults with young children were at lower risk of testing positive for SARS-CoV-2 and possibly also of developing COVID-19
- My views on how in Australia, with still little Covid transmission, good contact tracing and quarantining etc, is an effective and successful approach despite the dire predictions of some. Lockdown demands were wrong: Sydney shows how to fight COVID-19
- For children (0-9yrs) much higher numbers admitted with influenza and pneumonia in NSW in 2017 compared to covid in 2021. For pneumonia plus flu, 124 ICU admission compared to 11 cases for covid Flu plus pneumonia admissions (2017) were 4,109 compared to 303 for covid (2021).
- Want to go out, but decrease you chances of getting Covid? Dine outside as much as possible. It was Cold in Canberra last night (6 C) but if you rug up and if restaurant has outside heaters, still very nice dinner.
- Lockdown toll: One in eight have new mental health condition
- Australia's epidemic curve. Better than flattened - a major fall from around Mar 27. But we are now seeing a low level lingering tail. This is why at least till the end of our winter we will need to limit crowd numbers and keep physical distancing rules.
- Norway lifts COVID-19 restrictions, despite under 70 per cent of population being fully vaccinated
- During COVID, Sweden did not enforce strict lockdown measures. Instead relied more on voluntary mitigation. Excess all-cause mortality rates indicate that Sweden experienced fewer deaths per population during the pandemic than most high-income countries
