Scientists have found viruses similar to the strain that causes Covid-19 can survive on commonly-worn fabrics for up to three days. The study by De Montfort University in Leicester tested a model coronavirus on polyester, polycotton and 100% cotton. The results suggested polyester posed the highest risk. Microbiologist Dr Katie Laird, who led the study, said the materials, commonly used in masks, posed a transmission risk.
The material most commonly used to make surgical masks is polypropylene, either 20 or 25 grams per square meter (gsm) in density. Masks can also be made of polystyrene, polycarbonate, polyethylene or polyester.

Coup has started. First of many steps. Impeachment will follow ultimately~WB attorney Mark Zaid, January 2017
Scholars, nonprofit leaders and regulators in the specialized field of occupational safety say relying on surgical masks—which are considerably less protective than N95 respirators—is almost certainly fueling illness among front-line health workers, who make up about 11% of all known COVID-19 cases.
“There’s no doubt in my mind that that’s one of the reasons that so many health care workers are getting sick and many are dying,” said Jonathan Rosen, a health and safety expert who advises unions, states and the federal government.
The CDC’s current advice contrasts with another CDC webpage that says a surgical mask does “NOT provide the wearer with a reliable level of protection from inhaling smaller airborne particles and is not considered respiratory protection.”
Put simply, in worker safety, “a surgical mask is not PPE,” or personal protective equipment, said Amber Mitchell, president and executive director of the International Safety Center.

Are the magic masks super-spreaders?
Yes, in fact this was settled science before COVID even hit us..but ScIeNcE you know...so, there's that.
Don't be afraid to see what you see
Viruses are no danger, unless you share masks. For a mask to be a "super spreader", it would need to be warn by dozens of people. Not quite sure why anyone would do that. Even if the mask gets your virus, you already have it, so it does not matter.
Bacteria, and fungi are a different story. They can come out of your body, reproduce on the mask, and reenter your body in greater numbers. Remember, a virus cannot reproduce outside the body, so you are not going to get many viruses back. With bacteria especially, you can get an overwhelming number back.
So if we all wear masks for multiple days, sooner or later, a bacteria will start hitting us.
