Infant scabies
Hello, Dr.
Wu.
My child has been undergoing treatment for scabies for about three weeks now.
Since our whole family is being treated, my child is using permethrin cream while I am taking medication and applying a topical treatment.
During our follow-up appointment last week, both my child and I had some skin peeling, and the doctor mentioned that there were no visible mites on our bodies.
I occasionally still feel itching in the areas where I was originally bitten, and my child's flat red spots tend to become raised.
However, this week, my child has been developing more and more blisters on their hands and feet.
Could this be due to new bites? I'm quite distressed.
I have been washing our bedding and clothes in hot water every day, and I also clean the floors with bleach, including areas where we have been in contact.
What should I do about my child's condition? It seems like their hands and feet are not improving, and the red spots keep becoming raised.
What can we do to achieve better treatment?

If there are new lesions, caution is advised, and further confirmation may be necessary.
Old lesions may take weeks or even months to resolve.

More Info
Scabies, also known as sarcoptic mange, is a highly contagious skin condition caused by tiny mites that burrow into the skin, leading to intense itching and a rash. In infants, scabies can be particularly distressing, both for the child and the parents. It’s important to understand the treatment options and care tips to help alleviate the symptoms and prevent further outbreaks.
Treatment Overview
1. Topical Treatments: The most common treatment for scabies in infants is the application of topical scabicides, such as permethrin cream (often referred to as Elimite) or benzyl benzoate. These medications are applied to the entire body, from the neck down, and left on for a specified period, usually overnight, before being washed off. It’s crucial to follow the instructions provided by your healthcare provider regarding the application and duration.
2. Oral Medications: In some cases, especially if the infestation is severe or widespread, oral medications like ivermectin may be prescribed. However, this is typically reserved for older children and adults, as the safety and efficacy in infants are still being studied.
3. Symptomatic Relief: To manage itching, antihistamines may be recommended. These can help reduce the urge to scratch, which can lead to secondary infections. Topical corticosteroids may also be prescribed to reduce inflammation and itching.
Home Care and Hygiene
1. Cleaning and Disinfecting: It’s excellent that you are already washing bedding and clothing in hot water and using bleach to clean surfaces. Continue this practice, as scabies mites can survive for a short time off the body. Wash all clothing, bedding, and towels used by the infected individuals in hot water and dry them on a hot cycle. Items that cannot be washed should be sealed in a plastic bag for at least 72 hours to kill any remaining mites.
2. Avoiding Reinfestation: Since scabies is highly contagious, it’s essential to treat all household members simultaneously, even if they do not show symptoms. This helps prevent reinfestation and further spread of the mites.
3. Monitoring Symptoms: Keep an eye on your child’s symptoms. If the red spots or blisters continue to appear or worsen, it may indicate a secondary infection or that the treatment is not fully effective. In such cases, it’s crucial to consult your pediatrician for further evaluation and possible adjustment of the treatment plan.
Understanding the Symptoms
The presence of new blisters or bumps can be concerning. It’s possible that these could be due to several factors:
- Allergic Reaction: Sometimes, the skin can react to the mites or the treatment itself, leading to new rashes or irritation.
- Secondary Infection: Scratching can lead to bacterial infections, which may present as red, swollen areas or pus-filled blisters.
- Persistent Infestation: If the treatment was not fully effective, it could lead to ongoing symptoms.
When to Seek Further Medical Attention
If your child continues to experience symptoms despite treatment, or if you notice signs of infection (such as increased redness, warmth, swelling, or pus), it’s essential to return to your healthcare provider. They may need to reassess the situation, possibly performing a skin scraping to confirm the presence of mites or to rule out other skin conditions.
Conclusion
Managing scabies in infants requires a comprehensive approach that includes effective treatment, diligent hygiene practices, and close monitoring of symptoms. By following your healthcare provider's recommendations and maintaining a clean environment, you can help ensure a quicker resolution to your child’s condition. If you have any concerns or if symptoms persist, do not hesitate to reach out to your pediatrician for further guidance.
