What is Scabies?
Understanding the Scabies Mite
Scabies is caused by the Sarcoptes scabiei mite, a tiny creature barely visible to the naked eye. These mites burrow into the outer layer of human skin, where they lay eggs and feed. This burrowing activity is the primary source of the intense itching associated with scabies.
The female mite is the main culprit, digging tunnels and depositing eggs. The eggs hatch into larvae, which then mature into adult mites, continuing the cycle of infestation. The life cycle of the scabies mite, from egg to adult, takes about two to three weeks.
It’s important to note that scabies mites cannot jump or fly. They spread through direct skin-to-skin contact, such as holding hands or sexual activity. Sharing clothing, bedding, or towels can also transmit the mites.
Recognizing the Symptoms of Scabies
The hallmark symptom of scabies is intense itching, often worse at night. This is due to the mites’ increased activity during these hours. The itching can be so severe that it disrupts sleep and leads to skin sores from scratching.
A pimple-like rash often accompanies the itching. These pimple-like bumps can appear anywhere on the body, but common locations include the hands, wrists, elbows, armpits, genitals, and buttocks.
In infants and young children, scabies can affect the scalp, face, neck, palms, and soles of the feet. Tiny burrows created by the mites may also be visible as thin, wavy lines on the skin.
Diagnosis and Treatment of Scabies
A doctor can usually diagnose scabies by examining the rash and looking for burrows. Sometimes, a skin scraping may be taken to confirm the presence of mites, eggs, or fecal matter under a microscope. This helps to solidify the diagnosis.
Treatment for scabies typically involves a prescription scabicide cream or lotion, which kills the mites and their eggs. The medication is applied to the entire body from the neck down and left on for the prescribed amount of time, usually 8-14 hours. This ensures complete coverage and effectiveness.
All household members and close contacts should be treated simultaneously, even if they don’t have symptoms. This helps prevent reinfestation. It’s also essential to wash all bedding, clothing, and towels in hot water and dry them on high heat.
Scabies Transmission and Prevention
How Scabies Spreads
Scabies spreads primarily through direct, prolonged skin-to-skin contact. This is why it’s often seen in families, childcare facilities, and nursing homes. Close physical contact, such as holding hands, hugging, or sexual intimacy, provides the mites with an opportunity to transfer from one person to another.
While less common, scabies can also be transmitted through shared clothing, bedding, or towels. The mites can survive for a short period, about 24-36 hours, off a human host. Therefore, it’s essential to take precautions to prevent the spread of the infestation.
Scabies is not typically spread by casual contact, like shaking hands or hugging briefly. Prolonged contact is usually necessary for the mites to transfer.
Preventing Scabies Infestation
Preventing scabies involves avoiding direct skin-to-skin contact with infested individuals. If someone in your household has scabies, everyone should be treated simultaneously to prevent reinfestation. This proactive approach is crucial for effective eradication.
Regularly washing bedding, clothing, and towels in hot water and drying them on high heat can kill any mites that may be present. Vacuuming furniture and carpets can also help remove mites from the environment. These hygiene practices are essential in preventing the spread of scabies.
Avoid sharing personal items like clothing, towels, and bedding with others. This simple precaution can significantly reduce the risk of transmission.
Scabies Myths and Facts
Debunking Common Misconceptions
Myth: Scabies is a sign of poor hygiene. Fact: Scabies can affect anyone, regardless of their hygiene practices. The mites are attracted to human skin, not dirt or filth. Maintaining good hygiene is important, but it won’t prevent scabies infestation.
Myth: Pets can transmit scabies to humans. Fact: While animals can get mange, caused by a different type of mite, they cannot transmit human scabies. Human scabies mites can only survive on human skin.
Myth: Scabies only affects certain populations. Fact: Scabies can affect people of all ages, races, and socioeconomic backgrounds. Anyone can contract scabies through close contact with an infested individual.
Understanding the Realities of Scabies
Fact: Scabies is highly contagious. Direct skin-to-skin contact is the primary mode of transmission. Taking precautions to avoid contact with infested individuals is crucial for prevention.
Fact: Scabies can be effectively treated. Prescription medications can kill the mites and their eggs, eliminating the infestation. It’s important to follow treatment instructions carefully and treat all household members and close contacts simultaneously.
Fact: Itching can persist for several weeks after treatment. This is due to the body’s allergic reaction to the dead mites and their waste products. Antihistamines and topical corticosteroids can help relieve the itching.
Scabies Complications
Potential Complications of Untreated Scabies
Untreated scabies can lead to secondary bacterial infections. Scratching the itchy rash can break the skin, creating an entry point for bacteria. This can result in impetigo, cellulitis, or even sepsis in severe cases.
Crusted scabies, also known as Norwegian scabies, is a more severe form of the infestation. Individuals with crusted scabies have a significantly higher number of mites on their skin, leading to thick, crusted lesions. This form of scabies is highly contagious.
In rare cases, untreated scabies can lead to kidney problems. This is typically seen in individuals with crusted scabies and is thought to be caused by the body’s inflammatory response to the massive mite infestation.
Managing and Preventing Complications
Prompt diagnosis and treatment are essential for preventing complications. If you suspect you have scabies, see a doctor immediately. Early treatment can prevent the infestation from spreading and reduce the risk of secondary infections.
Avoid scratching the rash, as this can increase the risk of infection. Keeping your fingernails short and clean can also help prevent bacterial contamination. Using cool compresses and antihistamines can help relieve itching and reduce the urge to scratch.
If you develop signs of a secondary bacterial infection, such as increased redness, swelling, pain, or pus, contact your doctor immediately. Antibiotics may be necessary to treat the infection.

FAQ about Scabies
How long does scabies last?
With proper treatment, scabies mites are usually killed within a few hours. However, the itching may continue for several weeks after treatment. This is a normal reaction to the dead mites and their waste products. The rash will eventually clear up as the skin heals.
Is scabies a sexually transmitted infection (STI)?
While scabies can be transmitted through sexual contact, it is not classified as an STI. Scabies can be spread through any form of prolonged skin-to-skin contact, not just sexual activity.
Can I get scabies from my pet?
No, human scabies cannot be transmitted from pets. Animals can get mange, which is caused by a different type of mite, but this cannot infect humans.
