ADRIAN: WELCOME BACK TO OUR WELLNESS WEDNESDAY SEGMENT, IN PARTNERSHIP WITH UNITED HEALTHCARE. TODAY, WE’RE TALKING ABOUT FACE MASKS. THEY ARE A HOT AND POSSIBLY DIVISIVE TOPIC FOR MANY. WE ARE GETTING BEHIND THE SCIENCE BEHIND THE IMPACT WITH CORONAVIRUS. JOINING ME IS DR. HARKER. LET’S TALK ABOUT HOW MASKS CAN HELP AND WHO A MASK ACTUALLY PROTECTS. >> YEAH, SO MASKS ARE HELPFUL. WE HAVE SEEN WHEN TWO PEOPLE WERE A MASK, REGARDLESS OF WHETHER ANYONE HAS SYMPTOMS, THE SPREAD IS 2%. WHEN ONE PERSON WEARS A MASK AND ANOTHER PERSON DOES NOT, THE SPREAD OF COVID IS AROUND 70%. SO MASKS ARE HELPFUL WHEN YOU CANNOT SOCIALLY DISTANCE AND YOU ARE NOT AROUND PEOPLE YOU LIVE WITH. ADRIAN: SO PROTECTING BOTH PEOPLE WEARING THE MASK. >> CORRECT. ADRIAN: WHAT IS THE BEST WAY TO THEN WEAR IT SO WE CAN TRY AND AVOID TRANSMISSION OR POSSIBLY PICK UP ANY OF THE CORONAVIRUS? >> YEAH, SO THAT IS A REALLY GOOD QUESTION. I SEE LOTS OF PEOPLE WEARING MASKS INCORRECTLY. FIRST OF ALL, THE MASK DOES HAVE TO FIT SNUGLY, AND THAT MEANS COVERING YOUR NOSE. I SEE A LOT OF PEOPLE WHO HAVE THE MASK COVERING THEIR MOUTH BUT THEIR NOSE IS EXPOSED. AND THEN SECURED BY TIES OR YOUR LOOPS. AND IT HAS TO COVER YOUR CHIN. ADRIAN: KNOWS TO -- NOSE TO CHIN, COVERING IT ALL APPEARED WE HAVE SEEN DISPOSABLE MASKS AND ONES THAT ARE MORE OF A NET GATOR. ARE THEIR DIFFERENT RATES OF EFFECTIVENESS AND IS THERE ONE THAT WORKS BEST AS A FACE COVERING? >> [INAUDIBLE] -- FOR JUST THE GENERAL PUBLIC. THE N95 MASKS YOU NEED TO LEAVE FOR THE HEALTH CARE WORKERS. BUT YOU WANT YOUR CLOTH MASK TO BE BREATHABLE. YOU WANTED ALSO TO HAVE TIGHTNESS. SO LOOK AT IT IN -- YOU WANT IT TO HAVE A TIGHT WEAVE. LOOK AT IT IN SUN WIFE -- SUNLIGHT AND SEE IF YOU CAN SEE THROUGH IT. IF NOT, THE WEAVE IS TIGHT ENOUGH. A LOT OF MASKS HAVE LITTLE POCKETS SO YOU CAN PUT A HEPA FILTER IN. AND IF YOU DO NOT HAVE A HEPA FILTER, YOU CAN SUBSTITUTE THAT WITH INGENUITY. SO A LOT OF PEOPLE HAVE USED COFFEE FILTERS, PAPER TOWELS, SO LAWYERS IS BASICALLY WHAT I AM SAYING. THE MORE LAYER’S -- PLAYERS IS BASICALLY WHAT I AM SAYING. THE MORE LAYER’S, THE BETTER. ADRIAN: THERE ARE THINGS WE HAVE HEARD A LOT AT CITY COUNCIL AND COUNTY COMMISSION MEETINGS IN FLORIDA, PEOPLE ARGUING THAT FACE MASKS MAY ACTUALLY IMPACT BREATHING. ARE THERE SOME HEALTH CONDITIONS THAT WOULD MAKE WEARING A MASK WORSE OR IS IT A MATTER OF A DIFFERENT KIND OF MASK FOR MAYBE SOMEONE WITH THOSE KIND OF CONDITIONS? >> IT IS ACTUALLY BOTH, AND IT IS A GOOD QUESTION. LIKE EVERYTHING, THIS IS SUPPOSED TO HELP, SO YOU WANT IT TO BE EFFECTIVE. YOU ALSO WANT TO USE COMMON SENSE. FOR EXAMPLE, IF YOU ARE DEAF, IT IS GOING TO BE HARD TO RELIVE THROUGH FACE MASK. SO YOU MAY WANT TO USE A CLEAR FACE MASK, RIGHT? IF YOU HAVE BREATHING TROUBLE OR IF THERE IS DIFFICULTY WITH -- PEOPLE WHO ARE HAVING DIFFICULTY STAYING CONSCIOUS, THEY SHOULD PROBABLY NOT USE A FACE MASK. ALSO, IF YOU ARE EXERCISING, RIGHT, HEAVY BREATHING, YOU WANT TO DO IT -- YOU PROBABLY DO NOT WANT TO WEAR FACE MASK, BUT I WOULD CAUTION PEOPLE WHO ARE EXERCISING TO TRY AND DO IT OUTDOORS. SO, OBVIOUSLY, KIDS WHO ARE LESS THAN TWO WILL HAVE DIFFICULTY WEARING A FACE MASK. EVEN OLDER CHILDREN WILL HAVE DIFFICULTY, SO USE IT JUDICIOUSLY. FOR EXAMPLE, WHEN SCHOOL STARTS. I WOULD DO IT WHERE IT IS CROWDED. YOUR KIDS ARE NOT GOING TO BE ABLE TO WEIGH FACE MASK FOR AS LONG AS ADULTS ARE, AND EVEN SOME ADULTS HAVE DIFFICULTIES. ADRIAN: ABSOLUTELY. WE ARE SEEING MORE AND MORE OF THOSE MANDATES. DR. HARKER WITH UNITED HEALTH CARE, THANK YOU FOR HELPING US
