Getting to Know Scabies: An In-Depth Guide to Causes, Symptoms, Treatment, and Prevention
Scabies is a skin condition caused by a specific type of mite that burrows beneath the skin, leading to intense itching, particularly during evenings and nights. In this comprehensive guide, we will explore the causes, symptoms, treatment options, and preventive measures related to scabies.
Understanding the Cause of Scabies
Scabies is triggered by an infestation of tiny mites, measuring approximately 0.3 to 0.4 millimeters. While healthy individuals may host up to ten mites, those who are elderly or have compromised immune systems can harbor hundreds. Although scabies mites from animals like dogs and cats cannot multiply on human skin, they can still cause bothersome itching.
Recognizing Symptoms: Unveiling the Itch
The hallmark symptom of scabies is intense itching, which tends to worsen in the evening and night. This itching can occur anywhere on the body, except the head. Interestingly, the itching arises due to hypersensitivity to the mites’ feces. It typically emerges 4 to 6 weeks after infection, during which time an individual can unknowingly transmit the infestation to others. If re-infected, itching may occur within days.
Visible signs of scabies can include:
- Zigzag-shaped, thread-thin patterns under the skin, resembling centimeter-long trails. These patterns, known as scabies burrows, are most visible on hands and feet.
- Small blisters and red lumps in the affected areas.
- Tear marks, small wounds from scratching, and skin changes resembling eczema.
- In elderly or immunocompromised individuals, the presence of numerous mites may lead to crusts forming on the skin, a condition referred to as “crustous scabies.”
Taking Control: Self-Care and Preventive Measures
Dealing with persistent itching post-treatment is common due to residual mites or their feces triggering allergic reactions. This itching subsides as the body naturally sheds its outermost skin layer, eliminating the irritants.
To manage itching and reduce the risk of transmission, consider:
- Using over-the-counter hydrocortisone cream or antihistamine tablets to alleviate post-treatment itching.
- Informing school or preschool staff to prevent potential transmission to others.
- Avoiding contact with the elderly, as scabies can be particularly problematic for this group.
- Thoroughly cleaning your home to eradicate any remaining mites.
To ensure comprehensive home cleaning:
- Wash hands thoroughly with liquid soap and water, drying them with disposable paper towels.
- Launder bedding, clothing, towels, and textiles at a minimum of 60 degrees Celsius to eliminate mites.
- Clean children’s stuffed animals as well.
- Meticulously vacuum, including beds and furniture.
- Items like shoes and textiles that cannot be washed at high temperatures should be aired for several days.
Scabies Treatment Strategies
For accurate diagnosis, healthcare professionals may need to examine mites under a microscope. If diagnosed with scabies, follow these steps:
- Use Tenutex, an over-the-counter liquid medication applied to the body. The treatment is repeated twice at one-week intervals.
- Ensure all household members receive treatment simultaneously to prevent re-infection.
- In certain cases, prescription medications might be necessary, such as when using Tenutex isn’t feasible.
It’s crucial to clean your home diligently to avoid re-infection.
When to Seek Medical Care
Contact healthcare if:
- You suspect scabies, and scabies burrows are visible on your skin.
- You experience severe itching.
- Itching persists four weeks after treatment or recurs after temporarily subsiding.
- If you’ve had close contact with someone diagnosed with scabies, it’s important to undergo treatment, even if symptoms haven’t manifested yet.
By understanding the causes, recognizing symptoms, and following appropriate treatment and preventive measures, individuals can effectively manage and prevent the spread of scabies. If in doubt, seeking timely medical attention is key to successful management.
