The absence of symptoms does not mean that you are not infected, so take care of others - wear a mask.
Since last few weeks the mask regime has been strengthened - now everyone must wear respiratory protection on the street. Contrary to many different opinions about the effectiveness of masks and respirators, these measures do not seem redundant. Recent studies have shown that facial protectors do work and should never be neglected.

The main problem now, the researchers note, is that the majority of COVID-19 infections come from people who do not show or feel any symptoms of the virus. They may not even suspect that they are already carriers of SARS ‑ CoV ‑ 2. In Wuhan, which was the epicenter of the coronavirus outbreak, it was asymptomatic patients that caused the disease in 79% of all infected.
WHO recommended social distance of two meters is not effective enough indoors. After all, viruses transmitted by airborne droplets can remain in the air for hours in a confined space, and on the street they are easily carried by the wind. SARS ‑ CoV ‑ 2 appears in the air after sneezing, coughing and even the usual conversation of an infected person.

Thus, the safety of each person largely depends on contact with other people and the use of a mask. The mask must necessarily cover the mouth and nose , tightly fitting the face. The effectiveness of continuous outdoor respiratory protection has been proven in Hong Kong, Singapore and South Korea, where such measures were introduced immediately. This is what made it possible to avoid a large number of infected.
The absence of symptoms means your viral load is low or zero and your ability to infect others is entirely based on your viral load. If you don't feel sick, you could kiss people and barely one person would get infected, and they would probably already be with low immunity.
There has been several studies that have shown that if you don't have symptoms, you aren't infectious.
I'm amazed that anyone believes this story about being infectious without symptoms. I am medically trained to safely put piercings in people. When you cut people up for surgery, it's a lot more important because it's wide open, but piercings, as soon as the ring is in place, it's sealed and there's very little risk of anything getting into your blood.
Once upon a time, people believed that HIV could be transmitted by kissing. Guess what, it's not!
Coronavirus is not a blood borne infection, and 99% of transmission happens between people sharing a house with each other.
If you are sick, stay at home. If you think you have to wear a mask to go outside and be around people, you are assuming your are effectively a biological weapon. You are not a biological weapon. You are a human being. You have the capacity to think, and read some old (like, 1 year) medical texts about epidemiology of cold viruses. Nothing changed between now and then about how they spread and who can infect others.
Number one thing to be healthy - eat healthy, get regular exercise (not too much), spend time in the sun. Swim at the beach. The beach is the last place you can possibly infect anyone, sea water is antiseptic.
