Disinfecting Items of Scabies-Infected Individuals: Key Considerations

Disinfection of items used by individuals infected with scabies?

Hello, I would like to ask if a child's backpack or jacket (which is washed daily with bleach) could potentially have scabies mites? Is it possible for previously infected areas (which no longer have red spots) to still have raised bumps and continue to harbor the mites? Thank you for your response.

Yes, but the chances are low.
Skin and dandruff, with more close-fitting clothing.
It may cause itching and rashes that can persist for several weeks.

More Info

When it comes to scabies, it's important to understand how the mites that cause this condition can survive outside the human body and the implications for personal items like backpacks and clothing. Scabies is caused by the Sarcoptes scabiei mite, which burrows into the skin, leading to intense itching and a rash. The mites can survive for a short period outside the host, typically around 2 to 3 days, depending on environmental conditions.

Regarding your question about whether a child's backpack or coat could harbor scabies mites, it is indeed possible, especially if these items have been in close contact with an infected individual. However, regular cleaning practices can significantly reduce this risk. You mentioned that the items are soaked in bleach water daily, which is an effective method for disinfecting surfaces and fabrics. Bleach is known to kill scabies mites on contact, so this practice should help ensure that any potential mites are eliminated.

It's also worth noting that scabies mites do not live long without a human host, so the risk of transmission from items that have been cleaned is relatively low. If the items are washed and dried thoroughly, especially at high temperatures, this further reduces the likelihood of any mites surviving.

As for the infected areas on the skin, even after the visible signs of scabies (like red spots) have disappeared, it is possible for the skin to still show some residual effects. This can include small bumps or spots that may appear raised. These are often a result of the body's immune response to the mites and can take some time to resolve completely. However, if there are no active symptoms such as itching or new rashes, it is likely that the infestation has been cleared.

If you are concerned about the possibility of reinfestation or if the child continues to experience symptoms, it is advisable to consult a healthcare professional. They can provide guidance on further treatment options and confirm whether the scabies infestation has been effectively treated.

In summary, while it is possible for scabies mites to be present on items like backpacks and coats, regular cleaning with bleach and proper laundering should mitigate this risk. Additionally, residual skin changes after treatment can occur, but they do not necessarily indicate an active infestation. If symptoms persist or if there are any concerns, seeking medical advice is the best course of action.
