Symptoms and Causes of Fungal Nappy Rash

A baby’s skin is very delicate and easily irritated. Most babies will get nappy rash at some point before their first birthday and the rash can become fungally infected.

Nappy rash is a skin irritation that affects the skin around your baby's nappy area. It can become fungally infected which is really uncomfortable for your baby. You may find that they are unsettled and not sleeping well. If you find that the rash looks especially irritated and does not improve after a few days, then it may have become fungally infected.

When baby’s skin is exposed to irritants such as urine or faeces from wet or dirty nappies, germs on your baby's skin can change harmless chemicals in the urine into chemicals like ammonia. Naturally occurring candida yeast can then find its way into the rash resulting in a fungal infection. However, having a nappy on for too long isn't the only cause. Many babies get nappy rash no matter how clean and dry their bottom is.

Common symptoms of fungal nappy rash:

  • A rash that is bright red, raised with well-defined edges
  • The rash is surrounded by satellite spots or pustules

Possible causes of fungal nappy rash:

  • Nappy rubbing against sensitive skin
  • Using perfumed wipes, or powders and soaps which may irritate the skin
  • Urine or faeces from wet or dirty nappies
