Infants typically develop oral thrush around the age of______________?
Show answer Hide answer
Answer: B. 2-6 weeks
Explanation
Oral thrush in infants most commonly manifests between 2 to 6 weeks of age. Immature mucosal immunity and developing oral microflora make neonates susceptible to candidal overgrowth during this window. Candida albicans proliferates on the moist oral mucosa, producing characteristic white pseudomembranous plaques. Oral candidiasis is a fungal infection caused predominantly by Candida albicans yeast organisms. Infants frequently acquire the organism during passage through the birth canal or from environmental exposure. Risk factors include immature immune systems, recent antibiotic use, and poor hygiene of feeding bottles.
Pediatricians and dentists easily diagnose thrush by noting that the white plaques wipe away to reveal erythematous mucosa. Topical antifungal medications such as nystatin oral suspension are prescribed to clear the infection safely. Sterilizing pacifiers and nursing bottles is essential to prevent recurrent candidal infections in infants. 6 days is too early for typical thrush development, as colonization and fungal proliferation require a longer incubation. 10-12 weeks exceeds the peak age range when neonatal oral candidiasis typically presents clinically. 18 months is far beyond the typical neonatal thrush window, representing toddler age where it is less common.
