The Zika Virus and Swimming Pools

The Zika virus is spread to people through the bite of an infected Aedes species mosquito. *

Eliminating mosquitos and limiting your exposure to mosquitos will help reduce your risk to contracting Zika.


  • A properly disinfected, balanced and circulating pool is not a mosquito breeding risk
  • We don’t advocate spraying and contaminating swimming pools; however, spraying pesticides will become more common. The typical pesticide dosing is very small per acre. As a result, swimming pool contamination would be small
  • A pool cover, while not necessary, can be an extra layer of protection.  After pesticides have been sprayed, it is recommended to hose off the cover outside the pool area before returning it to the pool
  • Continue to maintain the proper pH, disinfectant levels, and circulation times per the recommendations in your local code or the NSPF Pool & Spa Operator Handbook™

Operators and service professionals who work outdoors are at greater risk and should:

  • Wear long sleeves and long pants
  • Use insect repellent with higher percentages of active ingredients
  • Be observant for potential standing water and either dispose of the water yourself or notify the owner (planters, buckets, birdbaths, etc.)
  • See your doctor if you suspect you could have contracted the virus and have cold or flu symptoms like; fever, rash, joint pain, conjunctivitis, or muscle pain and headaches

*According to the CDC, Zika can be passed from a pregnant woman to her fetus during pregnancy and through sexual contact from one person to another.  The virus can be passed sexually before symptoms start, while symptoms are occurring, and after symptoms end.  Using condoms can reduce the risk of transmitting the disease to your loved ones.
