Cryptosporidiosis associated with a swimming pool complex.

ABSTRACT

Twelve children and one adult in Gloucestershire fell ill with cryptosporidiosis in March 1992. Ten cases lived in or near a particular Cotswold town. Eight of these had visited a swimming pool within 24 hours of a suspected faecal accident, and two may have been secondary cases. Of the three cases who lived elsewhere, one was probably unrelated to the outbreak, one had visited the pool, and one was a contact of a boy who may have been the source of the outbreak.
