Answer

An alternative approach to prophylaxis is to treat all household contacts in the setting of acute PSGN in an effort to eradicate household transmission of nephritogenic strains. For invasive GAS infections (eg, necrotizing fasciitis, TSS), no data are available on which to base assessment of risk to household contacts. However, because of the devastating nature of these infections and the observation that invasive disease may be due to clonal outbreaks of more virulent strains, empiric antibiotic therapy of household contacts seems warranted.
