Swine Flu (H1N1) - Is Swimming Still Safe?

Can the H1N1 flu virus be spread through water in swimming pools or spas?

Flu viruses infect the human upper respiratory tract. According to the Center for Disease Control, there has NEVER been a documented case of influenza virus infection associated with water exposure. Swimming pool water that has been treated at recommended chlorine levels does not likely pose a risk for transmission of flu viruses. No research has been completed on the specific susceptibility of 2009 H1N1 flu virus to chlorine and other disinfectants used in swimming pools or spas. However, recent studies have demonstrated that free chlorine levels that are at least1–3 parts per million for pools and 2–5 ppm for spas are adequate to disinfect the avian influenza A (H5N1) virus. It is likely that other influenza viruses such as 2009 H1N1 virus would also be similarly disinfected by chlorine.

In other words, you can rest assured that it is safe to swim!
