Secondary infection with bacteria can occur and have the appearance of impetigo or school sores, with weeping and crusting.
Scaly patches which look like eczema may also develop.
The scabies mite may cause such a rash and this may not be easily diagnosed. As scabies was rarely seen for many years, many doctors had never seen a case. Now it has become so common, other itchy rashes may be mistakingly thought to be scabies and treated as such.
Finding and identifying a burrow confirms the diagnosis. Removing the mite and examining it under the microscope provides positive proof.
Some sufferers may have the rash and the itch for several years.
Once a correct diagnosis is made, the correct treatment can be applied. The various preparations available are all cosmetically acceptable and most people are prepared to carry out the treatment.
Benzyl benzoate lotion and gamma benzene hex-achloride are the most effective chemicals, just as they are for pediculosis or louse infestation.
