@LilMissRe thank you for sharing the informative video with the Korean infectious disease expert/doctor.
What jumped out for me:
Most infections are in those in 20/30s as these are less likely to wear masks & socialise in bars etc. Not effectively socially distancing. Whilst symptoms usually mild they spread to others.
Masks do work and offer some protection for obvious reasons.
WHO have advised against masks for general public as they want to prevent public stockpiling and priority should obviously be for front line medical staff.
WHO have not advised against masks for the public in some countries in Asia as more of a cultural norm.
18 months, very best case, for vaccine but hope other drugs will have a positive effect that are already being used for other conditions.
Korea tracking & tracing & monitor via a quarantine AP on phone.
Korea were prepared as had MERS/SARS to deal with previously.
