On masks I just read this lancet study
The widespread reported use of face masks combined with physical distancing increases the odds of SARS-CoV-2 transmission control. Self-reported mask-wearing increased separately from government mask mandates, suggesting that supplemental public health interventions are needed to maximise...
And a Nature study supported by the Zoe app.
Estimating the effectiveness of COVID-19 control measures requires large prospective data including symptoms and personal risk factors. Here, the authors used data from smartphone-based application and found that individual face mask use was associated with a 64% reduced risk of COVID-19 symptoms.
I took heart at 62% reduced risk even with various adjustments for social distance and risk areas.
There’s also a Bangladeshi study but can’t find the link atm. The reduced risk for N95etc masks over cloth were big, but reduced risk all around.
I think mask wearing is really a numbers game. If we all wear them in crowded areas numbers will reduce over all. It maybe that you’re unlucky anyway.
