Crypto-linked four cases prompt SD County pool investigation at Gaylord Pacific

San Diego County public health officials are investigating four cases of cryptosporidiosis tied to the Gaylord Pacific Resort pools, with exposures reported between July 24 and Aug. 15. Crypto can survive in well-maintained pool water and is resistant to chlorine, spreading via oocysts; symptoms include watery diarrhea 2–10 days after exposure, and people can shed the parasite even after symptoms resolve. Health officials advise thorough handwashing with soap and water and careful, hydrogen-peroxide-based disinfection, noting the illness is typically mild for healthy individuals but more serious for immunocompromised swimmers.
