Once again: masks are extremely valuable when you have no choice but to go out near other people; they reduce the probability of infect others, or being infected yourself. But, if anyone thinks they can go out near other people because they or the others have masks, even when it's not 100% necessary, then the mask has increased the probability of infection, which otherwise would be zero.

This is why it's important to understand that the masks are the secondary mean of protection: the primary one is not to go near anyone, at all.

Such cases naturally include medical workers, police, etc., but also the workers in supermarkets, pharmacies, etc., and optimally, all the customers buying the necessary food and medicines.

For the rest: don't go out, then you don't need to wear the mask either.

iMo:
I wonder whether to create a "simple" model how the R0 changes with applying face masks with efficiency "Me" from 0.1 .. 99.9 and social distancing "Sd" from 0.5 .. 10m could be so difficult.

For talented people on this EE blog:

1. the R0=2.5 in standard urban population with no social distancing, without any face masks
2. let's assume the droplets amount drops with square of distance (measured from the source person), muzzle droplets amount "Da"=3000 while talking, 40000 while coughing
3. consider social distancing (no masks) Sd=0.5 .. 10m -> what would be the R0(Da, Sd)?
4. add "source" face mask with Me1 = 0.1 .. 99.9 -> what would be the R0(Da, Sd, Me1)?
5. add "destination" face mask with Me2 = 0.1 .. 99.9 -> what would be the R0(Da, Sd, Me1, Me2)?

Suddenly, the government has practically claimed victory, and the prime minister Sanna Marin is giving political interviews aimed at their voters, the main content is how well they handled (yes, in past tense!) the situation. She especially highlights how the actions have happened (again, in past tense) at correct times, because the epidemic "was" here later compared to many other countries, such as Italy, it's OK to react later, as well. What she completely misses is that you should react comparatively earlier than Italy did. Yes, the government not only thinks it's OK to repeat the process seen in Italy; they don't fear saying it out loud!

The government has started talking about the whole crisis in past tense, and are mostly concerned about helping the economy to recover.

The schools have been partially reopened (for all 1st to 3rd graders); the teachers are terrified of such change. Despite starting the actions too late, last three days have been all about stopping the gradual increase of actions, and actually lifting some.

The trade union leader has hinted blackmailing for a pay increase of 10% in order to keep the nurses working. Of course, at such a time, such blackmailing is not tolerated anywhere; apparently we Finns are so forgiving that everybody just decided not to react to such comment at all. We hope she gets into her senses before it's too late. In such war-like conditions, blackmailing your owns and working against the health of the others easily costs your life.

Here is worse, to hazard the life of the health professionals ,it is rewarded with a palm at the shoulder. Now, we have 3500  infected between the health professional . Furthermore today, i have known that a mate of my mother has been reassigned to ICU,sooner or later my mother will too  reassigned . Simply , they are falling like flies.

I know that nuance is about as welcome to you as the swish of two bricks to a camel, but could you try not to boil someone's nuanced, reasoned explanation down to a "masks good"/"masks bad" choice and a rhetorical insult?

Uh oh....  That is a very bad sign...

Didn't you guys just announce 103 new cases today? 
At 626 total, that's a 15+% increase in one day. 

Sure, let's lift restrictions, this thing is over.   :palm: 
Well handled, there, gov't!
