Contrast to cultures that wear masks so they don't spread their germs ( virus ) onto others. Then contrast how well those different cultures are doing against this virus.
People are looking for that silver bullet in somekind of drug when in reality the silver bullet is right in front of them...they just are too ignorant to separate the bullet from stupid political alignments.
All these discussions about masks and other simple mitigation measures. They work, it takes time, but they work. Here in greater Lisbon area of Portugal it took about 2 months of slightly stricter "recommendations" to bring down the number of cases. Today we had 106 new cases, 62% of them in Lisbon. 2 months ago we were at 400 and 90% respectively.
Quite simply, 2 months ago the authorities were a too lax with deconfinement ina an area where population density is 7x the country average, where many working families live in small flats where it is not possible to isolate positive cases from the rest of the family; where tracing contacts is difficult due to 60+ nationalities. But it can be done, and it takes time.
Of course this "semi crisis"came in the middle of the tourist season, and Portugal suffered a lot with the restrictions from the UK. Well, spain was very happy by that, not so now...Spain is a mess, with all the regions implementing their own measures, and central government hanging to power by a string and no authority.
But really is quite simple - follow the 3Cs plus mask use, and it prevents exponential spreading.
