If a client calls to report an absence because their child has Adenovirus, ask them when they were last at the swim school. If the infected child was in the swim school within 2-3 days of infection:

  1. Notify the front desk of that location to let them know there has been a possible exposure. 
  2. Site supervisors and booking center should work together to keep an eye/ ear out for any further cases reported. 
  3. If more than one case is reported within the same week, notify General Manager. 

If a client calls and claims that their child contracted Adenovirus from our swim school, we can reply with the following response as appropriate:

“Thank you for alerting us. We are aware that Adenovirus is a common childhood illness and can be found in places where there is a high volume of children such as child care centers, grocery stores, schools, museums, playgrounds and possibly Hubbard. While we do perform daily cleaning to our facilities, we will ALERT our staff to take EXTRA care to clean common surfaces, play areas, and changing areas throughout the day. Please keep us updated with any concerns and please contact your pediatrician with any further questions. We hope your child feels better soon!”

In regards to a possible water transmission, the CDC states that while some forms of the Adenovirus can be spread through water, such as swimming pools, it is not as common. In regards to our pool water at HFSS, we are proud to say that we exceed the requirements for Maricopa County Environmental Health Code. For example, in our small pool, we have a minimum water turnover rate every 110 minutes whereas the Maricopa County Health Code only requires it to be within 8 hours. We also exceed recommendations on standard chemical maintenance by using high tech measures and UV light to neutralize microorganisms quickly and keep our water clean and safe for our clients and employees. 

Further questions regarding the care of our water, direct to a certified HFSS pool operator.
