What is the most important thing you can do to prevent infections? at what times should you do this?

1: The most important thing you can do is wash your hands with soap and water, it doesn't need to be hot.
2: Make sure your health care providers are wearing and using clean instruments.
3: Cover your mouth and nose, many diseases are spread through sneezing and coughing.
4: Get vaccined whenever your healthcare provider reccomends it.

This depends on your medical history and how you react to certain treatments.

If it's a smaller child or infant, place one on the middle of the chest and on the child's back. (if it is a bigger child with enough room for two, place one on the upper right/your left of the chest, and one on the lower left/your right) the pads should never touch each other.
