Thrush, also known as ciguatera and candidiasis, is a disease of the oral mucosa caused by Candida albicans infection. Thrush is mostly seen in infants and children who are weak or malnourished, especially those with poor digestion. Thrush can occur anywhere in the mouth, mostly in newborns from the birth canal, but also from unclean nipples or the fingers of feeders, and the mother’s nipples or rubber nipples are sources of infection. The main manifestation is mucosal congestion on the upper and lower lips, cheek mucosa, back of the tongue or soft palate, with scattered soft, snow-like spots that soon fuse with each other to form white, velvety patches. The patches are not very tightly attached and can be wiped off with a little pressure. There are usually no accompanying symptoms, but some children may become irritable, cry, have difficulty nursing, and sometimes have a mild fever. After the child is diagnosed with thrush, the mother and father can use a sterile cotton pad dipped in 2% baking soda to scrub the mouth, and the scrubbing should be done gently. Usually the disease disappears after a few days of medication, but thrush is particularly prone to recurrence, so parents should continue to use medication for a few days after the disease disappears to consolidate the effect and avoid recurrence, and try to cure it at once. Prevention and treatment methods: 1. Pay attention to your child’s oral hygiene and help him or her clean his or her mouth after feeding him or her, if the child is young, you can use warm wet gauze to clean the mouth, if the child is older, you can let the child rinse his or her mouth with water. If the child is breastfed, the mother should wash her hands with water and clean the nipples with a warm, wet towel before breastfeeding; if the child is fed with a bottle, then the bottle and nipple should be sterilized by boiling beforehand. 3. Do not use antibiotics indiscriminately. This is because when using broad-spectrum antibiotics for children, the antibiotics may kill the bacteria that inhibit Candida albicans, leading to a proliferation of Candida albicans, which causes thrush, a medical condition called dysbiosis. When treating your child for thrush, you should stop using antibiotics, or if you have a major medical condition that necessitates antibiotics, you should use them under the guidance of your doctor.
