Noma neonatorum is a big, scary word that means a really bad infection that can happen to babies who are brand new to the world.
Sometimes when a baby is born, they can get germs in their mouth that are really bad and can make them very sick. When these germs grow really fast, they can cause a big sore or hole in the baby's mouth. This sore can get bigger and bigger and can hurt the baby a lot.
Noma neonatorum mostly happens in parts of the world where it's hard to get good healthcare, like in Africa. But sometimes it can happen in other places too.
If a baby gets noma neonatorum, they need to get help from a doctor right away. This is because it's a very serious infection and can make the baby very sick. The doctor will give the baby medicine and may need to do surgery to fix the sore.
To prevent noma neonatorum, it's important to keep babies clean and make sure they don't get any germs in their mouth. This means washing your hands before you touch or feed a baby, and making sure their surroundings are clean too.
