Ringworm

The infection
known as “ringworm,” contrary
to its name, is not caused by a worm.
Instead, it refers to certain fungal
infections that form on the surface
of the skin. Also known as “tinea,”
ringworm is a common and contagious
infection that is especially observed
among children. Ringworm is a group
of conditions that can affect the skin
on the body (tinea corporis), scalp
(tinea capitis), groin area (tinea cruris
or jock itch), or feet (tinea pedis
or athlete's foot).
Causes and Risk
Factors
Numerous parasites, like bacteria and
fungi, thrive on and inside of our bodies.
Some of these parasites have useful
functions and are actually beneficial
to the body. However, others can multiply
under favorable conditions and lead
to infections. Ringworm is caused when
any of the several types of fungi grow
and multiply rapidly on the skin, scalp,
or nails. Several different species
of fungi can cause ringworm and Dermatophytes
of the genera Trichophyton and Microsporum
are the most common varieties.
Ringworm is contagious and can spread
among individuals by direct skin-to-skin
contact or by contact with contaminated
items such as combs, unwashed clothing,
and shower or pool surfaces. Those who
participate in contact sports such as
wrestling are also more susceptible
to such fungal infections. The favorable
environment for ringworm-causing fungi
is a warm, moist area. Therefore, areas
of the body wherein there is frequent
wetness (such as from sweating) or minor
injuries to the skin, scalp, or nails
can also develop this infection. Working
in close contact with water or caring
for those who are suffering from this
infection makes an individual prone
to such an infection.
