What is Cercarial dermatitis?

What is Cercarial dermatitis?

  • Cercarial dermatitis: A short-lived rash that occurs as an allergic reaction to larval (cercariae) infection of the skin. These particular parasites use birds and animals as their first hosts. Larval eggs are excreted in the faeces and when they land in water, they hatch into larvae which then infect certain aquatic snails. The infected snails release another form of the larvae called cercariae which then search for a bird, mammal host. When they enter the skin of a human they die as humans are unsuitable hosts but the skin can produce an allergic reaction.
  • Cercarial dermatitis: a sensitization reaction to repeated invasion of the skin by cercariae of schistosomes.

Who gets Cercarial dermatitis?

Profile for Cercarial dermatitis: Anyone who swims or wades in infested water may be at risk. Larvae are more likely to be swimming along shallow water by the shoreline. Children are most often affected because they swim, wade, and play in the shallow water more than adults. Also, they do not towel dry themselves when leaving the water.
