Skin infections are common health problems, with a higher frequency amongst children. In the NT, scabies and skin sores are amongst the commonest presentations in Aboriginal children to community health centres. 1 The bacteria on the skin do not usually cause infection, but the risk increases with humidity, hot weather, poor hygiene and especially if there is a break in skin integrity. Scabies is an extremely common factor in the NT, which underlies secondary impetigo or skin sores. 2 Less commonly, skin infections can lead to septicemia. Impetigo/skin sores The commonest causes of skin infections are Staphylococcus aureus, cultured in 86.7% of impetigo cases, and group A streptococcus (GAS), cultured in 29.2% of cases. 3 Other bacteria such as staph epidermis, E. Coli, group B streptococcus and gram-negatives cause skin infection in less than 5% of cases. There are very low rates of treatment failure due to these organisms. 3 Local studies have also confirmed the predominance of S. aureus in impetigo. 4 However, it is the GAS that is of greater concern, due to its potential to cause serious post streptococcal disease. Acute post streptococcal glomerulonephritis (APSGN) is strongly associated with skin infection, and NT communities regularly experience epidemics affecting large numbers of children. 5 Recent NT research has ...
