Scabies is endemic in certain populations but may be seen episodically or in epidemics in other populations. The prevalence of scabies is estimated to be more than 200 million cases worldwide.[3] However, this varies geographically and in some communities, particularly those that are sub-tropical and developing, prevalence may approach 70%.[3] The highest rates of endemic scabies are seen among people in the West Pacific, including Fijian children and Aboriginal Australians.[4] Overcrowded living conditions and poverty are associated with a higher prevalence of scabies. Scabies tends to peak in colder seasons, probably due to increased crowding and prolonged survival of mites away from the host in cooler temperatures. Young children and older adults are most frequently affected. There is no sex or ethnic predominance. Norwegian or crusted scabies is primarily seen in immunosuppressed patients.[5]
