Anyone can be at risk of getting impetigo, but there are things that can increase a person’s risk: - Age is the most important factor. Impetigo generally affects children between 2 and 5 years old. - Close contact with someone who is infected is a risk. Impetigo will spread easily through a family or places where people come together and create situations of close contact, like schools, daycare centers, or during activities like sports where skin-on-skin contact occurs. - Warm, humid weather gives impetigo more opportunities to spread. - Broken skin makes it easier for the bacteria to enter. It can enter through an insect bite or even a rash. - Health conditions can increase the risk of getting impetigo. Children with existing skin conditions are more vulnerable. Older people and people with diabetes or a weakened immune system are also more vulnerable.
