Bothell pool linked to cryptosporidiosis outbreak
An outbreak of cryptosporidiosis has been linked to the indoor pool at McMenamins Anderson School in Bothell. Public Health Seattle-King County announced on September 30 that an investigation into the facility suggests the illness may have spread to 14 cases.
The suspected exposure occurred between August 29 and August 30, 2026. Investigators determined that while the pool is well-maintained and adheres to King County health and safety requirements, the Cryptosporidium parasite is highly resistant to chlorine, allowing it to survive in the water for several days after an infected individual uses the pool.
Cryptosporidium is a diarrhea-causing disease spread through germs found in the feces of infected people or animals. According to the CDC, the parasite is commonly contracted when swallowed. Symptoms typically appear within two to ten days of infection and can last for one to two weeks.
