14 People Infected with Parasite After Swimming in Hotel Pool

**Cryptosporidiosis Outbreak Linked to Bothell Hotel Pool Investigated**

Public health authorities have concluded an investigation into a cryptosporidiosis outbreak connected to a hotel swimming pool in Bothell, Washington, a suburb located approximately 20 miles north of Seattle. The outbreak, which occurred at McMenamins Anderson School, a former junior high school transformed into a hotel, resulted in 14 reported illnesses at the end of August.

The King County Public Health Department identified the dates of exposure as August 29 and 30. Those affected reported a range of symptoms, including diarrhoea, fever, and nausea, after using the hotel’s pool facilities. The department strongly suspects that the causative agent, the highly contagious parasite Cryptosporidium, was introduced to the pool by an infected individual.

To ascertain the source of the outbreak, officials conducted interviews with six of the ill individuals to gather detailed information about their symptoms and pool usage. A subsequent inspection of the swimming area took place on September 21. Health inspectors found no violations during this examination, confirming that the facility operator had not recorded any incidents involving faecal matter either on the specific days of the reported illnesses or in the preceding ten days.

Despite the well-maintained condition of the pool, health officials warned that Cryptosporidium can survive for several days in chlorinated water. This resilience poses a significant challenge for pool safety, as the parasite is known to withstand chlorine levels typically used in such facilities. The department noted that adherence to health and safety regulations was present at the Anderson School pool.

In light of the outbreak, public health officials have urged swimmers to take precautions to prevent future infections. Their primary recommendation is to refrain from using swimming pools for at least two weeks following any episodes of diarrhoea or vomiting. The department also emphasised the importance of showering with soap before entering a pool to help mitigate the spread of illness.

Fortunately, the health department has indicated that the outbreak has now concluded. Their thorough investigation has allowed them to communicate that the risk of further transmission within the swimming pool is currently low. However, they continue to advocate for public awareness regarding hygiene practices when using communal swimming facilities.

As of now, McMenamins Anderson School has not publicly commented on the issue following the conclusion of the investigation. The hotel, known for its historical significance and unique accommodation offerings, will likely seek to reassure guests and visitors about its commitment to health and safety standards.

As this situation highlights, cryptosporidiosis is a reminder of the importance of maintaining hygiene in public swimming environments, prompting health officials to reinforce their messages surrounding safe swimming practices. With this outbreak now declared over, authorities hope that guests can once again enjoy the facilities without concern.

Public health officials continue to monitor waterborne illnesses closely, and they emphasise the importance of prompt reporting and response to instances of infectious outbreaks such as this one. The community is reminded to stay vigilant and to follow health guidelines aimed at ensuring a safe swimming experience for all.
