Crypto Illness Linked to Gaylord Resort; All Pools Reopened After Thorough Disinfection

The County has concluded an investigation into cryptosporidiosis exposure at swimming pools, spas, and the water park at the Gaylord Pacific Resort in Chula Vista.  The gastrointestinal illness, known as “Crypto,” is caused by a microscopic, chlorine-tolerant parasite that can trigger gastrointestinal symptoms, including watery diarrhea.

Resort guests reported illnesses after visiting the resort’s pools between July 24 and Aug. 15. Three cases were confirmed through laboratory testing, and a fourth was reported by a family member. Symptoms usually start two to 10 days after exposure and last one to two weeks.

The resort is private and not publicly accessible, so hotel staff directly notified all guests and day pass visitors who used the pools during the exposure window.

On Aug. 25, after being alerted by County staff, Gaylord Pacific voluntarily closed all pools and began a CDC-recommended hyperchlorination treatment to eliminate the parasite. The treatment included boosting chlorine levels, inspecting and cleaning pool filters, and maintaining elevated chemical levels until the water met safety standards.

County inspectors visited the resort on Aug. 26, 27 and 28 and verified that proper procedures were completed.  All pools, spas and water park features were cleared to reopen on Aug. 28.

If you have any questions about the status of the pool, please call the County Pool Program line at (858) 505-6900 or e-mail or call the Gaylord Pacific Resort.
