Everything to Know about Scabies

Scabies is more than just a troublesome itch; it is a highly contagious skin condition caused by tiny mites called Sarcoptes scabiei. These minuscule creatures burrow into the skin, resulting in severe itching and an uncomfortable rash. Understanding scabies is not only crucial for effective treatment but also essential for preventing its spread in communities.
In this post, we will cover the causes, symptoms, diagnosis, treatment options, and prevention strategies linked to scabies. The intention is to provide clear and comprehensive information that anyone can understand, whether you are experiencing symptoms or just seeking to educate yourself.

What Causes Scabies?
Scabies is triggered by an infestation of scabies mites, which are so small that they cannot be seen with the naked eye. These mites love warm and moist areas on the body. When they burrow beneath the skin, they cause intense itching, as most people with scabies will attest.
The primary way that scabies spreads is through skin-to-skin contact with someone who is infested. For example, sharing a bed or hugging an infected individual can put you at risk. This is especially common in crowded places like shelters, nursing homes, or classrooms.
In addition to direct contact, scabies can also spread through contaminated items. The mite can survive on clothing, towels, and furniture for up to 72 hours. Studies show that around 20% of individuals in crowded living conditions may become infested, highlighting the importance of proper hygiene and awareness in these environments.
The symptoms of scabies usually take 2 to 6 weeks to show up after the initial infestation, which can complicate identifying where the infection began.
Symptoms of Scabies
The signs of scabies typically include intense itching, particularly at night, and a rash that looks like tiny blisters or sores from scratching. The most common places for the rash to appear include:
Interdigital spaces (in between the fingers)
Wrists and elbows
Underarms
Genital area
According to the American Academy of Dermatology, about 60% of people with scabies experience a secondary bacterial infection due to scratching the itchy areas. This can prolong the discomfort and complicate treatment.
With awareness of these symptoms, you can act quickly to seek appropriate care and stop the spread of the infestation.
Diagnosing Scabies
A healthcare provider can often diagnose scabies by observing the symptoms and examining the affected skin. They will look for characteristic signs, such as tiny burrows, which appear as short, wavy lines on the skin.
In some cases, a skin scraping may be performed, where a doctor removes a small sample of skin to check for the presence of mites or their eggs under a microscope. Accurate diagnosis is essential because self-diagnosis can lead to delays in treatment and increased transmission.
Treatment Options for Scabies
The standard treatment for scabies involves prescription topical medications, known as scabicides. These medications are designed to kill the mites and relieve itching.
Commonly prescribed treatments include:
Permethrin cream: Often regarded as the first-line treatment, it is applied to all areas of the body from the neck down. Research indicates it has a cure rate of over 95%.
Lindane lotion: This option is effective but is typically reserved for individuals who cannot use other treatments.
Ivermectin: This oral medication is sometimes prescribed for severe infestations or when topical treatments are ineffective. It has been shown to help in about 80% of cases when levelled with topical treatments.
Following the healthcare provider’s instructions is critical for achieving effective treatment and minimizing the risk of reinfestation. Even after successful treatment, some individuals may still experience itching for several weeks due to the body's reaction to the mites.
Preventing Scabies
Preventing scabies primarily involves avoiding close contact with infested individuals and practicing good hygiene. Key strategies include:
Limit close skin contact: Avoid intimate situations with people known to have scabies until they have been treated.
Wash personal items: Regularly wash linens, towels, and clothing in hot water to destroy any mites.
Treat everyone in close contact: Ensure that family members or people living in close quarters with an infested person are treated simultaneously.
Increase awareness: Educating yourself and others about scabies can greatly aid in preventing its spread.
By implementing these strategies, individuals can significantly lower their chances of contracting scabies.
