How to avoid possible swimmer itch
With any open water swimming, it is important to know about swimmer's itch and how to prevent it
or at least treat it. It is caused by a parasite that is released from infected birds, aquatic mammals and snails.
The parasite is released into the water and can penetrate the skin. The parasite will die but can cause an allergic
reaction in some people and that is where the itching comes in. The way to prevent it is to towel dry the skin completely
after getting out of the water instead of letting the water evaporate from the skin. The initial symptoms are a tingling
at the site of penetration followed by an itchy rash which may be red and slightly raised or blistered and occurs within hours
of exposure. The rash is usually spared in the areas covered by clothing. Not all who are exposed (about
30%) will develop the rash as it is based on an allergic reaction. Treatment is not needed in mild cases, in those who
manifest a significant allergy cortisone cream can be tried initially. If this is not effective or a secondary
skin infection results from scratching, prescription medication may be necessary.
So enjoy your open water
swimming but be sure to dry your skin well with a towel after. You may want to consider bringing two towels, one specifically
for drying off after the swim portion. Repeated exposure to the parasie increases the likelihodd of sensitization and
resultant rash.
