Miliaria crystallina and miliaria rubra can occur in persons of any age, but the diseases are most common in infants. In a Japanese survey of more than 5,000 infants, miliaria crystallina was present in 4.5% of the neonates, with a mean age of 1 week. Miliaria rubra was present in 4% of the neonates, with a mean age of 11-14 days.

Three cases of congenital miliaria crystallina are reported. [22, 23, 24]

Miliaria profunda is more common in adults than in infants and children.
