Outbreak of cryptosporidiosis associated with a swimming pool in Andover.
An outbreak of eight cases of cryptosporidiosis in Hampshire over a period of eight weeks in the summer of 1996 was linked to use of one swimming pool. Cryptosporidial oocysts were not isolated from samples of backwash, but the presence of enterobius ova indicated faecal contamination and a case control study including the first four primary cases suggested an association with immersion in the pool. Even in small outbreaks case control studies can provide useful supportive evidence as to the possible source of infection.
