Scabion disease, more commonly and accurately known as scabies, is an intensely itchy skin condition caused by a tiny burrowing mite called Sarcoptes scabiei. This microscopic mite burrows into the outer layers of the skin, leading to a characteristic rash and severe itching.
Understanding Scabies: The Root Cause
The core of scabies lies with the nearly invisible eight-legged mite, Sarcoptes scabiei. These mites are responsible for the infection as they create tunnels or burrows just beneath the skin's surface. Inside these burrows, the female mites lay their eggs, which then hatch, and the larvae mature, perpetuating the infestation.
Recognizing the Symptoms
The most prominent symptom of scabies is intense itching, which often worsens at night or after a hot bath. This persistent itching is an allergic reaction to the mites, their eggs, and their waste products. Along with the itching, a characteristic skin rash typically appears, which can manifest as tiny red bumps, blisters, or visible wavy lines (burrows).
Common areas where the mites tend to burrow and symptoms appear include:
- Between the fingers and toes
- Around the wrists and elbows
- In the armpits
- Around the waistline
- On the inner thighs
- Around the nipples, genitals, and buttocks
How Scabies Spreads
Scabies is primarily transmitted through prolonged, direct skin-to-skin contact with an infected person. This can occur during close personal contact, such as during sexual activity, or within families and care facilities. Less commonly, it can spread through shared clothing, bedding, or towels if the infected person has crusted scabies (a severe form of the disease). Pets do not spread human scabies.
Diagnosis and Treatment Overview
Diagnosing scabies typically involves a healthcare professional examining the skin for signs of burrows and rashes. Sometimes, a skin scraping may be taken to identify mites, eggs, or fecal matter under a microscope.
Treatment for scabies involves prescription creams or lotions applied to the entire body, often from the neck down, and left on for a specific period before being washed off. Oral medications may also be prescribed in certain cases. It's crucial for infected individuals and their close contacts (even if asymptomatic) to be treated simultaneously to prevent re-infestation. Additionally, washing clothing, bedding, and towels in hot water and drying them on a hot cycle is recommended to eliminate any mites present.
