A panty spreads when its fabric is exposed and has a hole through it, usually by rubbing on the skin.
However, it can also be spreading by using its fabric to hold on to a wet cloth or by covering itself with other materials, like a pillow.
A pantry spread can be caused by a combination of factors, including: an allergic reaction, or from eating a contaminated item that is made from a certain type of panty fabric, such as fabric made from soy, wool, linen, or cotton fabric.
The garment may also be causing the spread by getting in the way of the panty itself, such that the garment is touching the fabric, as in the case of a cotton panty.
A person who has the infection can also spread the infection by touching or swallowing a contaminated material that has spread the bacteria, such the fabric from a cotton bra, a silk or fabric from an afghan, or a bra from a bra made of wool.
If you are experiencing any of these symptoms, call your doctor right away.
The spread can also happen if you are not wearing a protective garment such as a hat or mask.
