Scabies is a highly contagious skin condition caused by infestation with the Sarcoptes scabiei mite. These microscopic parasites burrow into the skin, leading to intense itching and irritation. While common, it’s a condition that requires prompt attention and treatment to prevent spreading and long-term discomfort.
What Is Scabies?
Scabies occurs when the female mite burrows under the skin to lay eggs. The presence of the mites, their eggs, and waste products triggers an allergic reaction, resulting in itching and a rash. Scabies is not a reflection of poor hygiene—it can affect anyone, regardless of cleanliness or lifestyle.
What Causes Scabies?
The Sarcoptes scabiei mite is the direct cause. Its ability to live and reproduce within the skin leads to infestation. Transmission typically occurs through:
- Prolonged skin-to-skin contact: This is the primary route of infection.
- Sharing items: Less commonly, infested bedding, clothing, or towels can spread scabies.
What Are the Symptoms?
Common symptoms include:
- Intense itching: Especially at night.
- Rash: Small red bumps or blisters, often arranged in lines.
- Burrow marks: Thin, grayish lines on the skin.
- Commonly affected areas: Between the fingers, wrists, elbows, armpits, waist, buttocks, and genitals.
How Do People Get Scabies?
The infection spreads through close contact, often between family members, sexual partners, or those living in close quarters. Though it is less likely, it can also spread by sharing contaminated items such as clothes or bedding.
Do I Need to Isolate If I Have Scabies?
Yes. Isolation is essential to prevent the spread:
- Avoid physical contact with others until treatment is complete.
- Wash clothing, bedding, and towels in hot water and dry them on high heat. Items that can’t be washed should be sealed in plastic bags for at least 72 hours to kill the mites.
What Is the Best Way to Get Rid of Scabies?
Treatment includes:
- Topical scabicides: Prescription creams like permethrin are applied to the entire body from the neck down.
- Oral medication: In some cases, ivermectin may be prescribed.
- Symptom relief: Antihistamines or soothing creams can help reduce itching, which might persist even after mites are eliminated.
Close contacts should also be treated simultaneously, even if they show no symptoms, to avoid reinfestation.
How Long Is Scabies Contagious?
Scabies remains contagious until treatment effectively eliminates the mites and eggs. After starting treatment, you are typically no longer contagious within 24-48 hours, though itching may continue as a reaction to dead mites.
