Some illnesses, such as head lice, MRSA, and pinworm, are unlikely to be spread in recreational water. However, there is a potential risk for spreading them at recreational water facilities through contact with other people or contaminated objects and surfaces.
Animals can be great companions, but if allowed in or near your pool, they can sometimes contaminate the water and spread germs that cause disease. Learn about keeping your pool clean and taking precautions when animals have been in or near the pool.
