Scabies is a skin infection that is caused by a tiny mite called Sarcoptes scabiei. These mites burrow into the skin, causing intense itching and a pimple-like skin rash. Scabies spreads quickly through close physical contact and is most commonly contracted through sexual contact. It can also spread among people living in close quarters.
The primary symptoms of scabies include severe itching (especially at night) and a skin rash that can involve lines or burrows where the mites have dug into the skin. The rash is usually present on areas such as between the fingers, on the wrists, in armpits, around the waist etc.
The standard treatment for scabies usually involves medications that kill the scabies mites and eggs. It’s important to consult with a healthcare provider for treatment if scabies is suspected.
Please note that even though mites can only survive away from human skin for about 48 to 72 hours, it’s still recommended to wash all bedding, clothes and towels that a person with scabies used in the 3 days before treatment. This prevents re-infestation.
Causes of Scabies
Scabies is an infectious skin condition caused by a tiny, burrowing mite known as Sarcoptes scabiei. Here are the primary causes of scabies:
1. Direct Skin-to-Skin Contact: This is the most common way scabies is transmitted. The mite can easily transmit between people if there is close, prolonged contact, such as among family members or sexual partners.
2. Infected Items: The scabies mite may also survive for a short time off the human body. Therefore, people may get scabies from infected items like clothing, towels, bedding, or furniture that have been used recently by a person with scabies.
3. Overcrowded Living Conditions: Scabies is often seen in crowded areas where there is a lot of close contact, like nursing homes, hospitals, child care facilities, and prisons.
4. Immune System: People with weakened immune systems or certain conditions that affect the skin (such as HIV, leukemia, etc.) may be more susceptible to scabies infestation.
It’s important to note that scabies has nothing to do with personal hygiene; even the cleanest people can get a scabies infestation. The condition is highly contagious and can affect individuals of all ages and social classes.
Risk Factors of Scabies
Scabies is a skin infection caused by the infestation of a microscopic mite known as Sarcoptes scabiei. The following are the risk factors associated with scabies:
1. Close Proximity: Scabies can easily be spread through direct, prolonged, skin-to-skin contact with a person who is already infested. This occurs commonly among family members or sexual partners.
2. Crowded conditions: Scabies is often found in ill-kept care facilities, nursing homes, or among people living in close, crowded conditions. The mites can transfer from person to person quickly in these environments.
3. Poor hygiene: Scabies can easily infest warm, humid places including beddings and clothes. If these items are not regularly cleaned, they can host mites and lead to infestation.
4. Weakened immune system: Individuals with a weakened immune system due to conditions like HIV/AIDs or a recent organ transplant are at higher risk of getting scabies.
5. Age: Young children and the elderly are particularly susceptible because their immune system is weaker. Scabies can quickly spread in places where these groups are found in close proximity, such as kindergartens and nursing homes.
6. Travel and regional lifestyles: There’s a higher risk of scabies in regions and circumstances where people live in close quarters.
Remember, scabies is not related to one’s cleanliness level or socioeconomic status. Even those who are extremely clean and developing these in developed countries can still acquire this skin condition.
Signs and Symptoms of Scabies
Scabies is a skin infestation caused by a mite known as Sarcoptes scabiei. It causes intense itching, and typically a rash, due to an allergic reaction to the mites. Here are several signs and symptoms of scabies:
1. Intense itching: This is often worse at night and may lead to sleep disturbances.
2. Rash: The infestation often causes a rash that can appear anywhere on the body, but is often on the hands, between the fingers, wrists, and elbows. In infants and young children, it may also be found on the head, face, neck, palms, and soles of the feet.
3. Sores: These can occur from scratching the itchy skin. Repeated scratching can lead to skin infections such as impetigo.
4. Thin, irregular burrow tracks: These are made up of tiny blisters or bumps on your skin. Each burrow typically ranges from 2 to 10 millimeters in length but can be longer. They are usually seen in the webbing between the fingers, the inner side of the wrist and elbow and the buttocks.
5. Scaliness or roughness of the skin: With crusted or “Norwegian” scabies, a severe form of the disease, the skin may appear crusted or scaly.
It’s important to remember that symptoms usually appear 2 to 6 weeks after exposure if the person has never had scabies before. In those who have had scabies, symptoms usually appear 1 to 4 days after exposure. If you or someone else has these symptoms, it is recommended to visit a healthcare provider for an examination. Treatment is usually with medications that kill the mites and their eggs.
Diagnosis Scabies
Scabies is a skin condition caused by the infestation of a microscopic mite called Sarcoptes scabiei. These mites burrow into the upper layer of the skin where they live and lay their eggs, causing intense itching and a pimple-like rash.
The primary symptom of scabies is extreme itchiness, which is often worse at night. The rash can appear anywhere, but often shows up on the hands, in between the fingers, on the wrists, elbows, armpits, the waist, and even on the soles of the feet.
Scabies spreads quickly through close physical contact, making it common in crowded places where close body contact is frequent.
Diagnosis typically involves examining a skin scraping under a microscope to look for the mites, their eggs, or their fecal matter.
This condition is treatable with medications that kill the mites, often requiring a prescription from a doctor. All members of a household or close contacts should be treated at the same time to prevent re-infestation. It’s also important to clean all clothes, bedding and towels used by the affected person to prevent further spreading.
Treatment of Scabies
Scabies is a skin condition caused by the Sarcoptes scabiei mite. These mites burrow into the skin and cause itching and a rash. Scabies is very contagious and can spread quickly through close physical contact in a family, childcare group, school class, nursing home or prison.
Treatment of scabies generally involves medications that kill scabies mites and their eggs. Here are the common treatments:
1. Permethrin cream (Elimite): This is the most commonly used treatment for scabies. It’s considered safe for adults, pregnant women, and children as young as 2 months old.
2. Lindane lotion: This medication is used if Permethrin cannot be used but is generally not recommended for pregnant women, people with a history of seizures, or for those who weight less than 110 pounds.
3. Crotamiton (Eurax, Crotan): This medication is available as both a cream and a lotion, and is applied once a day for two days.
4. Sulfur (in petrolatum): This is a safer option for infants and pregnant women, applied nightly for three consecutive nights.
5. Oral medications: For cases that present as crusted scabies, more resistant, or in outbreaks in community settings, oral Ivermectin can be used.
In addition to these treatments, itching can also be helped with antihistamines, soothing lotions like calamine, or for severe cases, corticosteroid pills can be used. It’s important that all family members and close contacts of individuals with scabies are also treated, because the mites can live away from human skin for 48-72 hours, and can potentially infest others or cause a re-infestation.
Finally, it is recommended that along with a patient, all of their close contacts such as family members, sexual partners, and other close physical contacts should also be simultaneously treated in order to prevent reinfection.
Thoroughly washing all clothing, bed linens, and towels that a person with scabies has used is also necessary.
Keep in mind that you will continue to itch for a couple of weeks after successful treatment because of an allergic reaction to the mites. But, if you still have new burrows or rashes a month after treatment, it means the scabies are not completely eradicated and you may need repeat or alternative treatment.
You should contact and visit a healthcare provider for a full evaluation and treatment options if you believe you may have scabies.
Medications commonly used for Scabies
Scabies is a condition caused by tiny mites that burrow into the skin. It’s often treated with medications that kill scabies mites and their eggs. Here are the most commonly-used ones:
1. Permethrin cream: This is the most used treatment for scabies. It’s a topical cream that’s applied all over the body, from the neck down and washed off after 8 to 14 hours. It’s considered safe for adults, pregnant women, and children aged 2 months and older.
2. Lindane lotion: This is an alternative treatment for scabies, generally used in those who can’t tolerate other treatments. It can, however, have severe side effects like seizures and therefore isn’t the first line of treatment.
3. Crotamiton cream or lotion: This medication is not as effective as other treatments and is generally not the first choice. It gets applied daily for 5-7 days.
4. Ivermectin: This oral medication is only used in cases where the infestation is severe, or the patient has an immune system disorder. It might be used in people with a large number of mites, those who cannot apply creams, when the disease has failed to respond to other medications, or for other reasons.
5. Sulfur ointment: This may be used for infants and young children, and in those with a sensitivity or intolerance to first-line medications. It’s usually applied for several nights.
It’s important to note that these medications might kill the mites and eggs quickly but itchiness can continue for a few weeks. Additional treatment such as antihistamines, steroid creams, or antibiotics might be needed to manage allergic reactions or secondary skin infections. Scabies is highly contagious, and any suspected cases should be treated promptly to prevent further spread.
Always consult a doctor before starting any medication regimen. They will recommend the appropriate treatment based on your medical history, the severity of the infestation, and any other factors that may be unique to your circumstances.
Prevention of Scabies
Scabies is a contagious skin disease caused by a tiny mite. Here are several steps you can take to prevent an infestation:
1. Avoid close physical contact with individuals diagnosed with scabies until they’ve completed their treatment regimen. The mites can quickly spread via skin-to-skin contact.
2. Do not share personal items with an infected person. This includes clothing, bed linens, towels, or other objects that may have mites on them.
3. Wash all clothing, bedding, and towels that an infected person has used in the two days before treatment. Use hot water and dry in a hot dryer, or dry-clean items. If something can’t be cleaned this way, place it in a sealed plastic bag for one week.
4. Maintain personal hygiene: Although scabies is not a result of poor hygiene, regular bathing can be associated with a lower likelihood of getting scabies due to less frequent skin-to-skin contact.
5. Treat all close contacts: Often, anyone living in the same household, caregivers, and sexual partners should be treated at the same time, even if they are not showing symptoms.
6. Prevent reinfestation: Follow-up care is important. It can take 2 to 4 weeks for symptoms to appear after you’re infected. It’s possible to spread scabies even if you don’t have symptoms, therefore follow your healthcare provider’s instructions closely to prevent reinfestation.
Remember, if you think you may have been exposed to scabies, it is vital to seek medical attention immediately. Treatment typically involves medications that kill scabies mites and their eggs, and they’re usually applied from neck downward, left on for eight hours, and then washed off.

Complications of Scabies
Scabies is a contagious skin condition caused by a tiny mite called Sarcoptes scabiei. While treatable, it can present several complications if it is not addressed promptly. Here are a few potential complications of scabies:
1. Secondary Infection: The most common complication of scabies is a bacterial skin infection. The incessant itching caused by scabies can lead to scratching, which then causes sores. These open sores can become infected by bacteria.
2. Impetigo: A common secondary infection resulting from scabies is impetigo, a superficial infection of the skin that typically leads to sores and blisters.
3. Kidney Problems: In rare and severe cases, these secondary skin infections can progress and lead to other issues such as post-streptococcal glomerulonephritis, a kidney disease.
4. Crusted scabies: Also known as Norwegian scabies, is a severe form of scabies that occurs in people with compromised immune systems. Instead of hosting a dozen or so mites on their skin, a person with crusted scabies may host millions. Consequently, crusted scabies is highly contagious and can be tougher to treat.
5. Infestation in a large community: Scabies can also create public health challenges if an infestation occurs in a large community like a nursing home, hospital, or prison, where it can spread rapidly in the crowded conditions.
6. Psychological distress: The persistent itch and knowledge of infestation can cause significant anxiety and stress, leading to sleep disturbances and a decrease in the quality of life.
It’s very important to get medical help if you suspect you or a family member has scabies. Early intervention can help prevent or manage the complications.
Home remedies of Scabies
