Hello: For a detailed introduction to scabies, you can refer to the article on the Dermatology Expert Health Network at http://www.drskincare.com.tw/Qa/Index.aspx?CID=15.
The risk of infection is low unless there is prolonged direct contact with an infected person.
However, if there are unusual skin manifestations, it is advisable to consult a nearby dermatologist for diagnosis and treatment at http://www.derma.org.tw/user_finddoctor.php.
Thank you!

More Info


Scabies, caused by the Sarcoptes scabiei mite, is a highly contagious skin condition that can spread through direct skin-to-skin contact or by sharing items that have been in contact with an infected person. The mites can survive off the human body for a short period, typically 2 to 3 days, on clothing, bedding, or other personal items. Therefore, touching items used by someone with scabies does pose a risk of infection, especially if those items have not been washed or treated.

In your case, since you mentioned that you touched items belonging to a person with scabies, it is important to consider a few factors regarding the likelihood of infection:
1. Immediate Handwashing: You indicated that you washed your hands after the contact. This is a crucial step in reducing the risk of transmission. Washing your hands thoroughly with soap and water can help remove any potential mites that may have been transferred to your hands.

2. Type of Contact: The risk of infection is higher if you had direct skin contact with the infected person or their skin flakes. If your contact was limited to touching inanimate objects, the risk is lower, especially if you took precautions afterward.

3. Duration of Exposure: The longer the mites are in contact with the skin, the higher the chance of transmission. If your contact with the items was brief and you washed your hands immediately afterward, the risk of developing scabies is significantly reduced.

4. Symptoms: Scabies typically presents with intense itching, especially at night, and a rash that may appear as small red bumps or blisters. If you start to notice these symptoms within a few weeks after your exposure, it would be advisable to consult a healthcare provider for evaluation and possible treatment.

5. Preventive Measures: To further minimize the risk of infection, ensure that any clothing or bedding that may have come into contact with the infected person is washed in hot water and dried on a hot cycle. Items that cannot be washed should be sealed in a plastic bag for at least 72 hours to ensure any mites die off.

In summary, while there is a risk of scabies infection after touching items used by an infected person, your immediate handwashing significantly reduces that risk. If you remain vigilant for symptoms and take preventive measures with potentially contaminated items, you can further protect yourself from infection. If you have any concerns or develop symptoms, it is best to seek medical advice for appropriate diagnosis and treatment.

Dr. Wu Yuxin reply Dermatology
No, please rest assured. Scabies mites or their eggs can transfer from the patient's skin flakes to the health insurance card, and then attach to your skin. It takes time for them to invade. As long as you wash your hands during this period, you can wash them away.
