According to the Centers for Disease Control and Prevention (CDC), chlorine can kill methicillin-resistant Staphylococcus aureus (MRSA).

If the chlorine and pH levels are correct, MRSA cannot survive in chlorinated water for very long. There are no reported cases of MRSA spreading through contact with chlorinated water.

However, people can get MRSA if they have an open cut or wound that comes into contact with the bacteria elsewhere, such as in locker rooms or showers.

Improper management of pools and jacuzzis can also allow bacteria such as MRSA to grow.

To be safe in recreational pools, people can follow these precautions:

  • only using pools and jacuzzis that maintain good disinfectant and pH levels in the water
  • showering for at least 1 minute before getting in the water
  • avoiding sharing towels and other personal items with others
  • washing towels and bathing suits after every use
  • keeping open cuts or wounds covered with a watertight bandage or waiting to go swimming until they heal

People should not use pools or jacuzzis if they have piercings or surgical wounds that are still healing.

Those with compromised immune systems should speak with a doctor before they use recreational swimming facilities.

People with current skin infections should avoid getting in the water until they have healed. Potential signs of a MRSA infection include an area of skin that:

  • is swollen and inflamed
  • leaks pus or fluid
  • feels warm to touch

The National Health Service (NHS) in the United Kingdom notes that people should get an urgent doctor’s appointment if they have these symptoms. Skin infections can spread within the body quickly and may become serious if they do.
