Scabies, does that ring a bell? This contagious skin disease is caused by a tiny mite named Sarcoptes scabiei. Contrary to popular belief, scabies does not only affect people with poor hygiene: it can affect anyone, regardless of social background or cleanliness level. In Switzerland, it remains a reality, especially in environments where contact is frequent, such as schools or nursing homes. In this article, we will explore together the symptoms of scabies, its causes, and how it is transmitted, to help you better understand this condition and know how to protect yourself.
Symptoms of scabies: How to recognize them?
The first symptoms of scabies usually appear between 2 to 6 weeks after contact with the mite, but if you have had scabies before, they can occur in just a few days. Here are the main signs to look out for:
- Intense itching: Often worse at night, it is caused by an allergic reaction to the mite, its eggs, and its droppings.
- Small red rashes: You might also notice bumps, small red blisters, or wavy lines that look like mini-tunnels on your skin. These marks mainly appear between the fingers, on the wrists, elbows, around the navel, buttocks, or on the genitals.
- Scratch wounds and crusts: The itching may cause you to scratch, leading to wounds and crusts on the skin. Sometimes, this also leads to secondary infections like impetigo.
Note, however, that these symptoms can be more subtle in the elderly or immunocompromised, so do not hesitate to consult a doctor if you have any doubts.
What are the causes of scabies and the risk factors?
The mite responsible for scabies burrows under your skin and digs tunnels to lay its eggs. This makes scabies particularly contagious since its transmission mainly occurs through prolonged direct skin-to-skin contact, such as hugs, prolonged handshakes, or sexual contact. Risk factors for scabies include:
- Close and prolonged contacts: Scabies is easily transmitted during hugs, long handshakes, or sexual contact. Such contact is particularly common with your partner, in family, school, or institutional settings.
- Sharing clothes or bedding: Although less common, the mite can survive on fabrics (clothes, sheets) for several days and infect someone else. Transmission through infested objects is therefore possible. It is even more important to clean infested objects to prevent the spread of scabies.
- Collective living conditions: Crowded conditions in boarding schools, nursing homes, or daycares facilitate transmission.
As you can see, scabies does not come from a lack of hygiene. Anyone can be affected, even in a clean environment.
Transmission of scabies: How does it happen?
Scabies is mainly transmitted through direct, prolonged, and frequent contact with an infested person. Contrary to what one might think, pets are not involved in the transmission of human scabies. Dogs and cats can have their own form of scabies, but it does not survive on humans. It is also possible to get infected by sharing items such as clothes or bedding, but this is rare because the mite only survives a few days outside the human body.
Scabies is a contagious disease that can affect anyone, regardless of your age or lifestyle. By knowing its symptoms, causes, and modes of transmission, you can act quickly to treat scabies and avoid passing it on to those around you. If you think you have scabies, do not hesitate to book an appointment with your doctor for a diagnosis and appropriate treatment. Do not let this disease ruin your daily life: quick treatment is key to regaining healthy skin.
