HI, thanks for using healthcare magic

It is possible that the lesions may be either fungal infection or impetigo which is a bacterial infection that can spread.
Some persons may have a combination.

Impetigo needs to be treated with oral antibiotics and fungal infections require treatment with topical agents for 2 to 3 weeks.

Because they can be spread, contact with other persons may need to be limited.

It would be best to see a doctor for assessment and treatment.

I hope this helps
