Masks? Basically useless unless you don't like to wash your hands and can't stop yourself from putting your fingers in your nose and mouth.
The "confirmed" cases often use tests which are not confirmed to be accurate, and this week's media push that cases are increasing could easily be due to the mass testing being done in ERs, ICUs, hospitals (high comorbidity group) so it doesn't reflect the general population and the rate could be rapidly falling as mass representative testing has not been done at all. Actual rate likely around 0.1%, similar to a heavy flu season.
