R0: susceptible to all, R1: resistance to one, R2: resistance to two, R3: resistance to three, and ≥ R4: resistance to four and more antibiotics. MDR= multidrug resistance. is computed from the total number of S. aureus; is computed from a total number of isolates, based on which MDR definition is applied.
