Scabies in infants :
Scabies is a common itchy rash seen in children and infants that is highly contagious. It is caused by a small bug known as a mite. (The scientific name of the mite is Sarcoptes scabiei.) The female mite typically enters the skin through skin folds, such as the space between the fingers, and burrows or invades the skin, forming a red “tract.” She then proceeds to lay eggs in the skin, which will later hatch into larvae. The first sign of a scabies infection (actually it is an infestation, but the two words tend to be used interchangeably for scabies) is usually several small (1–2 mm) red, crusty bumps on the hands and feet. The skin of infants is often more exposed and more sensitive, and, therefore, these lesions can develop into large blistering lesions or pus-filled bumps. Scabies is extremely itchy because the human immune system forms an allergic reaction to the mite and the eggs that hatch.
The Pediatrician may prescribe lotion or cream with Permethrin to kill the mites, to apply nightly and rinse off in the morning, for 2 or 3 consecutively days, and also prescribe antihistamine oral medication.

Itching may take up to 3 weeks to go away, as your child’s immune system continues to react to dead mites. However, new burrows and rashes should stop appearing 48 hours after effective treatment.
Your Pediatrician should remind you to launder towels, bed linens, and clothes used by your child in the previous 72 hours and to vacuum carpets, rugs, and upholstered furniture.
Most kids can return to school the day after the treatment is complete.
