There is no excuse for SWAB shortages. To the left is a STREP test. The test comes with it's own swabs. It is a matter of design and any patent rights in an emergency. There are plenty of manufacturers in the USA that can produce these products.

THE CUE-TIPS AND STORE BRAND SWABS ARE STERILE. BUY THEM OFF THE SHELVES. THERE IS NO HOARDING OF THESE SWABS THAT MADE THE NEWS.
