Thank you Miguel for that referenced input.
Definitely food for thought...!
My country has high rates of TB and particularly MDR and XDR strains.
Wearing masks for suspected cases in health facilities was something I had proposed when I was part of the management of the Dept Health.
At the time, it was rejected due to the potential stigmatization of TB patients.
I then suggested giving all patients masks and using them for positive health slogans.
"Not feasible!" I was told.
I retired a year ago.
Now everyone is required to wear masks everywhere.
