Yes. The cloth masks and N95 masks with no exhaust valve will hold-in the almost invisible spray of a cough or sneeze. However, the poor edge-seal means that someone with these masks are not well protected from breathing-in some airborne mist, which is why the 6-foot social distancing is mentioned so often.
A college student will gladly have sex with a stranger from the same college that they met at a college bar, and they will use a condom. However, take those same two students and ask them individually if they would have sex with someone that they were attracted to, but then they found out that this person has herpes, chlamydia, or AIDs?...
if that person used a condom. I can't think of anyone who would say yes. You have AIDs? No problem, we'll just use a condom.
There are two big problems with Covid-19. The first is that you can have it and be infecting everyone you talk to for two weeks before you show symptoms. The second problem is that the virus is highly aerosolized by simply breathing. Most upper respiratory infections usually need a cough or sneeze to infect those around you.
Also, there is a low health-crisis rate for young people and middle-age people (yes, I know sometimes even they die, but...). So most of the population has it and is spreading it because they don't personally "feel sick".
This is a highly contagious agent that is statistically killing off the elderly around the world. The 1918 flu (20+ million dead) was especially hard on children, but "most" seniors appeared to be immune, or very lightly affected. This Covid-19 is hard on seniors, especially if they have a secondary condition (smokes, Diabetes, overweight, high blood pressure, etc).
This graph is only for fatalities by age (I know this graph is from China and a couple months old, but the newer graphs from around the world are similar. This one was easy to read with less irrelevant clutter)
COPPER BUTTON-POKER
My wife is "at risk", so I do the grocery shopping once a week. I noticed at the ATM, gasoline,and grocery store I had to push buttons or touch a touch-screen. I have plenty of thin gloves from way before the Covid-19, but to make my supply last and to help others with information, I made a copper button-poker.
Copper has a very strong "anti-bacterial" property. I took a common BIC pen from a "ten pack" at the dollar store, cut a 1/4 inch off of the tail, Inserted an inch of 12-ga solid copper wire from Romex 12-3 scrap cable (used to wire 120V AC in houses). Then I put a second cap over it which is marked by a felt marker. One end is still an ink-pen, and the other end is a copper tip with a cover.
Since I was blocking-off the ink-tube top vent-hole with the copper, I poked a vent hole just below the copper with a razor so the ink would still flow
