Abstract
Scabies, the human skin disease caused by infestation by the mite Sarcoptes scabiei var. hominis, causes considerable morbidity and mortality through direct effects and as a result of secondary bacterial infection. Scabies is a truly neglected disease, largely absent from the global health agenda, and its huge burden of disease is largely underappreciated. We contend that coordinated, global efforts to control this ubiquitous pathogenic mite are both important and achievable.
Highlights
Scabies affects people of all countries, the most vulnerable sectors of society
The highest incidence is in tropical climates, with rates of up to 25% overall and up to 50% in some communities in the South Pacific and northern Australia [2,3]
Infestation is frequently complicated by bacterial skin infection, including impetigo, cellulitis, and abscess due to Streptococcus pyogenes and Staphylococcus aureus (Figure 2)
Summary
Scabies affects people of all countries, the most vulnerable sectors of society. Infestation is frequently complicated by bacterial skin infection, including impetigo, cellulitis, and abscess due to Streptococcus pyogenes and Staphylococcus aureus (Figure 2). Such bacterial skin infections predispose to serious suppurative and nonsuppurative sequelae. Skin infection with S. pyogenes can lead to the nonsuppurative complications of acute post-streptococcal glomerulonephritis (APSGN) and possibly acute rheumatic fever. Outbreaks of APSGN coincide with those of scabies [11], and asymptomatic renal disease is common [12] These insults to the kidney in childhood contribute to the development of chronic kidney disease and subsequent renal failure in adulthood [13]. Further information is needed to quantify the indirect costs, including complications in later life
