Hot tubs are home to a lot of bacteria, but the big concern is that the heat and bubbles from the hot tub combine to make the bacteria more dangerous. Bacteria can become part of the mist that forms over the hot water, making it easy to inhale the infectious agents. If you have low white blood cells, you can easily succumb to an infection from hot tub bacteria. Crowds are an invitation for germs.
