What is scabies and why is it so contagious?
Scabies, better known as mange, is a skin infection caused by a tiny mite that burrows into the skin. Although the mite is microscopic, it can cause severe itching and visible skin changes. The infection is primarily spread through close skin contact between people. Therefore, mange is often seen in environments where many people are in close contact for long periods of time.
Scabies mites are typically transmitted through direct physical contact. This can occur, for example, between children who play closely together or students who live together or share beds. In some cases, infection can also occur via bedding, clothing, or towels. However, this usually requires that the material has been used shortly after an infected person.
This means that the infection can easily spread in households, dormitories, and institutions. If one person in the home contracts scabies, there is therefore a high risk that others will become infected. This is precisely why prompt treatment is important.
Why does scabies often affect children and students?
Children and students often have many close social contacts. In daycare centers, schools, and dormitories, it is completely normal to be physically close to other people. This creates ideal conditions for scabies mites to spread from person to person.
In children, infection often occurs through play, hugging, or sharing naps in institutions. Young children are rarely aware of the symptoms at first. Therefore, the infection can spread before it is detected.
Students are also a group in which scabies is frequently seen. Many live close together, share sofas, or stay overnight at each other's homes. At the same time, the symptoms can initially be confused with dry skin or allergies, which sometimes delays treatment.
When many people are gathered in one place, scabies can therefore quickly develop into a minor outbreak.
The most common symptoms of scabies
The most common symptom of scabies is intense itching. The itching often gets worse in the evening and at night. This is because the mites are most active when the body is warm under the covers.
Many people also experience small red bumps or rashes on the skin. These may resemble insect bites or eczema. They can occur in several places on the body, but are often seen in specific areas.
Typical locations with symptoms are:
- Between the fingers
- On the wrists
- Around the navel
- On buttocks or genitals
- Under the arms
In children, the rash can also appear on the face, scalp, and feet. If you experience persistent itching without a clear explanation, it may be a good idea to get checked out.
How the dermatologist makes the diagnosis
If you suspect scabies, you should contact a dermatologist. The diagnosis is often based on the symptoms and an examination of the skin. The dermatologist will typically look for the characteristic burrows in the skin made by the mites.
In some cases, the doctor may gently scrape the skin to examine the material under a microscope. Here you can see the mite itself, eggs, or feces from the mite. However, this is not always necessary to make a diagnosis.
The most important thing is to clarify whether the symptoms are caused by scabies or another skin condition. Several skin diseases can look similar. Therefore, it is advantageous to get a professional assessment.
Once the diagnosis has been made, treatment can begin quickly.
Treatment of scabies – how to get rid of the mites
Scabies is typically treated with a prescription cream or lotion. The medication is applied to the entire body from the neck down—and in children, often also to the face and scalp. It is important that the treatment is carried out thoroughly to ensure that all mites are removed.
The treatment should usually remain on the skin for 8-12 hours. It is then washed off again. In some cases, the treatment must be repeated after a week to ensure that any new mites are also killed.
Remember to treat everyone in the household
Even if only one person has symptoms, it is often recommended that everyone in the household be treated at the same time. This is because infection may have occurred before symptoms appear.
If not everyone is treated at the same time, the infection can quickly return. Therefore, coordination at home is an important part of the treatment.
The itching may continue for several weeks after treatment. This does not necessarily mean that the treatment is not working.
How to avoid infecting others
Once you have been diagnosed with scabies, it is important to limit the spread of infection to others. Until treatment is complete, you should avoid close physical contact with people outside your household.
It is also recommended to wash clothes, bedding, and towels at a minimum temperature of 60 degrees Celsius. Items that cannot be washed can be placed in a sealed bag for at least three days. This will kill the mites, as they cannot survive without human skin.
You should also vacuum mattresses, sofas, and other places where you have spent a lot of time. Although the risk of infection via furniture is lower, it can be a good extra precaution.
Once the treatment has been completed correctly, you will usually no longer be contagious.
When should you see a dermatologist?
You should contact a dermatologist if you experience severe and persistent itching without any obvious cause. This is especially true if several people in your household or social circle have similar symptoms.
Early diagnosis can make a big difference. The sooner scabies is detected, the lower the risk of the infection spreading. This can save both you and your loved ones a lot of discomfort.
You should also consult a dermatologist if symptoms persist after treatment. In some cases, a new treatment or a different type of medication may be necessary.
If the skin also becomes red, warm, or painful, there may be a bacterial infection on top of it. This also requires medical evaluation.
