It's always been a healthy measure to wear a mask. This thread reminded me of a groomer in our first issue of PetGroomer.com Magazine in 2011. She got a Zoonotic sinus infection Pseudomonas Aeruginosa and was seriously ill for a long time. Diane (article) is not the only groomer we know that has suffered from these type of infections. The magazine article can be read at https://petgroomermagazine.com/articles/groomer-health/sinus-infection-pseudomonas-aeruginosa/
Diane visited THIRTY doctors and faced skepticism and 3 years to find a doctor to treat her effectively. "I have learned a lot since my infection. It has been an interesting journey. I have seen more than thirty doctors over the past three years—many of whom were skeptical of my symptoms. It took a year and a half to get a Pseudomonas diagnosis and three years to find a doctor who knew how to treat this type of infection. It has taught me how to be proactive and persistent."
Quality UV light treatments last a long time and are a worthy investment even for vans today in addition to a proper mask. You treat your tools, surfaces and air quality killing 99% of the baddies.
Diane (article) mentions it led her to surgery and she lost much of her taste and smell. You can be disabled from even practicing your profession for some time. And if you don't have health insurance, it could be a terrible financial burden with loss of income, and cost of treatment. If a mask and UV can help prevent this, what a bargain. CV-19 is relatively nothing compared to Pseudomonas. Oh yes, don't forget the gloves with Pseudomonas (zoonotic diseases), they can be spread skin-to-skin.
