Norwegian Scabies: Infection Risks and Prevention

Norwegian scabies

Hello, I would like to ask, there is a wheelchair-bound patient, an elderly woman with Norwegian scabies, who happened to be at the entrance where our nursing staff frequently pass.
I was just about to take out the trash and was very careful not to touch the door, but I am unsure if I accidentally touched it.
I would like to know if this poses a risk of transmission.

Norwegian scabies, also known as crusted scabies, is a severe form of scabies caused by the mite Sarcoptes scabiei. Unlike typical scabies, which may present with a few itchy lesions, Norwegian scabies is characterized by a high burden of mites and crusted lesions that can cover large areas of the body. This condition is particularly contagious due to the sheer number of mites present, making it a significant concern in healthcare settings, especially in close quarters like nursing homes or hospitals.

In your situation, where you encountered a patient with Norwegian scabies while managing waste, the risk of transmission largely depends on several factors. Scabies is primarily transmitted through direct skin-to-skin contact. The mites can also survive for a short period on surfaces or clothing, but they do not live long without a human host. The likelihood of transmission from touching a door handle or similar surfaces is relatively low, especially if you did not have direct contact with the patient or their lesions.

However, it is essential to maintain strict hygiene and preventive measures in such environments. Here are some key points to consider:
1. Personal Protective Equipment (PPE): Always wear appropriate PPE, including gloves and gowns, when caring for patients with Norwegian scabies. This helps prevent direct contact with the mites.

2. Hand Hygiene: After any potential exposure, such as touching surfaces in the vicinity of an infected patient, thorough handwashing with soap and water or using an alcohol-based hand sanitizer is crucial. This practice significantly reduces the risk of transferring any potential mites to your skin.

3. Environmental Cleaning: Regular cleaning and disinfection of surfaces and shared equipment in healthcare settings are vital. Mites can survive on surfaces for a limited time, so frequent cleaning helps minimize the risk of indirect transmission.

4. Isolation Protocols: Patients with Norwegian scabies should ideally be placed in isolation to prevent the spread of the infestation. This includes using single rooms whenever possible and limiting their movement within the facility.

5. Early Treatment: If you suspect that you may have been exposed, it is advisable to consult with a healthcare professional. They may recommend preventive treatment or monitoring for symptoms, which can include intense itching and the development of new lesions.

6. Awareness of Symptoms: Be vigilant for any signs of scabies in the following weeks. If you develop symptoms, seek medical advice promptly. Early intervention can prevent further spread.

In summary, while the risk of transmission from a brief encounter with a patient with Norwegian scabies is low, it is essential to adhere to strict infection control measures. By practicing good hygiene, using PPE, and being aware of the signs and symptoms, you can significantly reduce your risk of contracting scabies. If you have any concerns or experience symptoms, do not hesitate to reach out to a healthcare provider for guidance.
