Thrush, also known as ciguatera and leucoderma, is an infection by a fungus and is a common disease of the oral cavity in children. It forms a white patchy film on the surface of the oral mucosa and is mostly seen in infants and young children. The disease is caused by Candida albicans infection. This fungus can sometimes be found in the oral cavity and can develop when infants are malnourished or debilitated. First, there must be a source of infection, such as a caregiver with ringworm, tinea pedis or vaginitis, or unclean bottles stored or nipples, and it is important to find the cause to get to the root of the problem. Baby thrush is caused by bacterial infection, and recurrent attacks can occur when the baby is weak. In addition to strengthening resistance, pay more attention to oral hygiene, every time after eating, give the baby a few mouthfuls of plain water to drink to clear oral residues and avoid breeding bacteria. You can use a disinfectant cotton pad dipped in 2% baking soda water to scrub the mouth, scrubbing when the action should be light, you can also take a mycophenolate grinded into powder, add 5 ml of glycerin mix, apply to the affected area. Usually the disease disappears after a few days of medication, but thrush is particularly prone to recurrence, so parents should continue to use the medication for a few days after the disease disappears to consolidate the effect and avoid recurrence. If thrush recurs, it is recommended to use Dafuccan capsules dissolved and applied to the mouth to reduce recurrence.
