Recurrent mumps in children can be caused by immunocompromise, respiratory infections, and local anatomical abnormalities.
1. Immunocompromise: The immune system of children is not yet mature and is easily affected by external infections, which leads to the recurrence of mumps.
2. Respiratory infections: Some children develop parotitis associated with upper respiratory tract infections, in which germs enter the parotid duct system retrogradely through the parotid ducts from the oral cavity and end up in the peripheral ducts or parotid gland parenchyma, leading to inflammation.
3. Local anatomical abnormalities of the parotid gland: cystic dilatation and delayed emptying of the terminal parotid ducts reduces the defense capacity of the ductal system, leading to recurrent attacks of parotitis.
There may be other reasons for children to get mumps repeatedly. It is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
