Scabies rash can be identified only if it is accompanied by other symptoms of scabies. If you have a severe, persistent rash that doesn’t seem to ease up it might be caused by infestation with scabies mites. Scabies rash is characterized through itching and soreness and it tends to intensify at night. Scabies rash may also become very irritated after taking a hot shower or bath. If the skin appears to be blistery and scratched and the presence of small burrows is revealed on the surface of the skin, it is a possible sign of scabies rash and appropriate dermatological treatment is required.
An overwhelming number of 300 million people worldwide are diagnosed with scabies each year. Scabies can be very easily acquired by simply touching a contaminated person. Although scabies is very contagious, scabies rash can’t be transmitted from a person to another. Scabies rash usually occurs when the body develops allergic reactions to scabies mites and their feces. The only contagious aspect of scabies involves the mite infestation. If the mites responsible for causing scabies are transmitted to a person, they will quickly infest the skin and the symptoms of scabies will occur within a few days. Scabies mites can be acquired through direct contact with an infested person or by touching or wearing contaminated clothes or personal items. Scabies mites can live without their human hosts for about 3 days and therefore they can easily contaminate bed sheets, clothes, towels, etc.
The main cause of scabies in people is contamination with a particular type of mite, called Sarcoptes scabiei var. hominis. This microscopic mite lives only on the bodies of human hosts and an infected person can spread it to hundreds of other persons.
It is important to note that scabies rash, just like other scabies symptoms, doesn’t occur due to improper hygiene. Although in the past, when the true nature of scabies wasn’t completely understood, people considered scabies rash to be the consequence of poor hygiene, today the cause of scabies rash is clear to most people. It is true that scabies occurs mostly to people from the lower classes of society, but this has nothing to do with hygiene. The factors that facilitate the transmission of scabies are overcrowding and situations that involve a lot of physical contact (factory workers). Hygiene can neither facilitate the occurrence of scabies, nor prevent it.
The most common symptoms of scabies are inflammation, discomfort, pain, swelling of the skin, pustules, burrows, nodules. However, the most intense of all seems to be the scabies rash. This symptom of scabies occurs as a result of allergic reactions to the mites’ feces, secretions, eggs and larvae.
Scabies rash is among the first symptoms that occur and it is usually the last one to disappear. Even if the condition is appropriately treated with topical medications, scabies rash may persist for another few weeks! This is due to the fact that even after they die, the mites remain under the skin and continue to produce allergies that cause scabies rash. The mites’ secretions contain substances that are toxic to the human body. However, there are ways of easing the itch, soreness and pain characteristic to scabies rash. Dermatologists usually prescribe hydrocortisone and antihistamine along with the treatment for scabies. These topical medications are usually in the form of creams, gels and ointments and they ameliorate scabies rash. However, if the scabies rash persists and even intensifies after a few weeks, it is a sign that the mite infestation hasn’t been eradicated and the treatment needs to be repeated.
