is the cause of flat warts?
Warts, including flat warts, are caused by members
of the extensive human papillomavirus (HPV)
family. For the most part, flat warts are caused
by HPV types 3, 10, 28 and 49. The most common way
to become infected is by direct skin contact from
one person to another. Transmission of the virus
is facilitated by small defects in the skin
barrier such as scratches or cuts. When one has
contracted the virus in one place of the skin it
is quite easy to spread it to other locations. A
well known way is through shaving.
Flat warts can persist for years but will (as a
rule) disappear without treatment. Topical
application of tretinoin cream and adapalene gel
are among the treatments that are available for
flat warts. However, no available treatment
offers a guarantee of cure...
